Re: [ccp4bb] Microscope camera

2024-04-25 Thread Darren Hart
Have you considered a Raspberry Pi with camera, or camera mount with 
your existing lens:


https://www.raspberrypi.com/products/#cameras-and-displays

Photos and livestream will be easy to set up. You could try motioneye to 
give you a livestream and take pictures on demand, or at defined time 
intervals.

Greetings, hive mind,

We have an old (but still useful) Nikon SMZ stereomicroscope that we use for 
mounting crystals. I’d like to attach a digital camera to the phototube, both 
to capture crystal images for archival purposes, and also to live-stream as a 
teaching tool.

I’d be grateful for any suggestions for an inexpensive option here.

When this camera was new we used it with an SLR that captured images on *film* 
(this is where the students gasp). We’ve since gone through one digital camera 
that probably still works, but the interface and software have become 
obsolescent. Meanwhile, the microscope keeps on truckin’; interesting to 
reflect on the relative lifetimes of analog vs. digital tools…

Thanks in advance for any suggestions,

Pat

Re: [ccp4bb] OFFTOPIC question "Two plasmids in one host cell"

2021-01-03 Thread Darren Hart
The pACYC vectors (probably your p15ori plasmid) is said to have a copy 
number of ~10 copies per cell while your other plasmid is likely in the 
hundreds - see:


https://blog.addgene.org/plasmid-101-origin-of-replication

The protein expression level from the lower copy number plasmid is 
usually a bit lower, but not always.


For sequencing, we use primers that are specific to the pACYC vector so 
it does not matter if there is a second higher copy plasmid present in 
the miniprep.


To increase the amount of pACYC vector for sequencing, you can always 
amplify the copy number by adding spectinomycin to a growing culture - 
this inhibits protein synthesis, but the low copy plasmids continue to 
replicate to hundreds of copies per cell.

Hi All,

I have two constructs having different ori, p15ori and M13 ori, 
different promoters araBAD promoter and LacI, and different antibiotic 
resistance chloramphenicol and Ampicillin respectively.
I am managed to get the transformants and getting the expected result 
after blunt digestion with the EcoRV enzyme. Since both the plasmids 
have the site for EcoRV. But the p15 ori has a low copy number that's 
why I am seeing the very faint band as compared to other plasmid in 
the sample.


So I would like to know is there any way that I can quantify the low 
copy number plasmid.
Because I am not able to sequence it with the specific primers it 
could be due to its low concentration.


Please advise.

Thank you.

Thank you Patrick,

RNA structure is still structural biology, so I think relevant
here.  It seems to me that RNA as a thermometer would be an easy
hypothesis to test? Has anyone measured virulence vs temperature
in cell culture?

The 3D structure of the genome is no doublt important.  I wouldn't
want to try crystallizing the whole thing, but I wonder if this
might be an excellent target for cryoEM?  A challenge for that "we
can classify our way out of anything" philosophy?  And the result
would most certainly be interesting.

out suggesting that wild-type influenza has multiple "RNA

of influenza.  Similar mechanisms may exist in other
respiratory viruses, including Covid.

Re: [ccp4bb] Off-topic: (micro)array image analysis software

Hello,

You could run Image Quant TL in a VM (parallels, vmware or virtual box).

For this appliation (arrays), we use an old program called VisualGrid

(in linux).

Hello,

clearly off-topic but maybe someone here is experienced in the 
analysis of array scans and can offer some advice? That would be 
beautiful. Here’s the problem: I want to test an ELISA-based HT array 
for phosphorylation profiling of a whole pathway, with almost 200 
antibodies at once. The array company offers free scanning of the 
arrays, i.e. we do the experiment, sent the slides back, and receive 
the scans as raw images in tiff format. Can anyone suggest a suitable 
program to analyse such images of array scans on a Mac? There are six 
replicates per antibody per slide so in theory a good basis for at 
least semi-quantitative analysis - but finding a program to analyse 
these data is a real pain. The scans are obtained with a GenePix 
scanner I am being told but the instrument’s software does not run on 
a Mac. I tried ImageJ, which is open source and runs but needs some 
plugin for arrays that does not work for me (I suspect it worked for a 
previous version of ImageJ). I also tried TIGR Spotfinder, which in 
theory seems the perfect program (plenty of documentation), is also 
open source and Mac compatible - but when I try to compile it several 
files seem missing from the sourceforge package (and I cannot find 
another source).


Does anyone use either ImageJ with the array plugin or the Spotfinder 
and can assure me that these options are still being developed or 
maybe knows for sure they are dead and not worth investing any more 
time? Or, even better, could point me to a program that runs on a Mac 
and is suitable for array analysis (it does not actually have to be 
free as long as it works for users who do not write code). I do have a 
GAL file for the images.


Many thanks for your help and sorry for the spam!

Dear colleagues

We have been working on a protein that is produced as a pro-peptide, 
cleaved internally and reassembled into a complex. The interacting 
regions are the new C and N-termini at the cleavage site, so no 
rearrangement or loss of part of the protein is involved. The 
resulting interacting region is quite intricate, with a helix bundle 
and beta-sheet composed of members of each partner protein.


I wonder if there are other examples of such processing required for 
folding/assembly of a functional complex? I'm not talking of 
processing involving removal of termini or internal regions like 
signal removal in transported proteins or maturation of preproinsulin, 
for example. I'm interested in examples where a propeptide is cleaved, 
then the two proteins reassemble in a complex via interactions of the 
similarly oriented new termini.


Any suggestions most appreciated.

Thanks a lot!

Re: [ccp4bb] off-topic: bug busting

2014-02-04 Thread Darren Hart
Adapted from periplasmic fractionation protocol, but for cytoplasmic 
proteins:


1. Incubate resuspended cells with lysozyme in normal buffer but with
   20% sucrose.
2. Spin down sphaeroplasts (unbroken cells with no cell wall - ultra
   fragile). This also removes periplasmic proteases.
3. Resuspend white pellet in buffer of choice and freeze-thaw. Or
   dilute buffer for osmotic shock. Or sonicate *very* lightly -
   perhaps using an aging sonicator!
4. Gives complete lysis from 2 ml to 2 litre culture volumes very
   reproducibly, and avoids proprietary bug-buster type detergent mixes.


See this paper - it also greatly increases purification (10-fold) of low 
abundance his tag proteins that are otherwise outcompeted by periplasmic 
components (siderophores?)

Re: [ccp4bb] Expressed protein hinders cell lysis?

2012-06-22 Thread Darren Hart
As a suggestion:


   1. Perform your lysozyme treatment in buffer with 20% sucrose.
   2. Then pellet your still intact cells and remove supernatant (cells
   pellet is white and cell lack walls - sphaeroplasts). Periplasmic
   proteases,  metallophores, etc are all washed away.
   3. Then resuspend in your lysis buffer and sonicate - cells are very
   fragile and burst easily.

 Greetings, everyone. We need to ask your advice on an issue with one of
 our proteins expressed in E. coli Rosetta cells. This yeast-derived
 protein has a very low yield compared to others we work with, and we think
 it is because the cells are hard to lyse: even after 3 cycles in a cell
 cracker the solution barely changes colour.

 We have no problems lysing Rosetta cells expressing other yeast-derived
 soluble proteins, and we usually obtain enough for our crystallisation
 screens. For the aforementioned protein we have already tried using STAR
 cells, varying the contents of the lysis buffer, sonicating, or adding
 FeSO4 to the solution (we think the protein binds Fe or Mn because it is
 yellow), but to no avail.

 Searching the ccp4bb archive and other resources did not help, so we would
 like to ask 2 questions to the community in order to focus our efforts
 better:
 1. How can a recombinant protein make a cell harder to lyse?
 2. Do you have any suggestions to avoid this effect?

 We appreciate any input, and will be sure to post a summary for future
 reference once this issue is solved.

Re: [ccp4bb] Expression of Viral proteins for crystallography

2012-01-24 Thread Darren Hart
I think the explanation is this:
The source is natural viral RNA which is a mixture of naturally mutated
sequences (e.g. flu forms such a quasispecies)
See:
http://www.virology.ws/2009/05/11/the-quasispecies-concept/

The pooled RNA has an average sequence that you see when you sequence the
pooled cDNA (individual mutations are hidden by the averaging effect of
having many sequences present).

But when you clonally separate DNA molecules by transformation (1 plasmid
enters 1 cell to yield 1 colony), you see each individual molecule
represented 100% in the sequencing chromatogram from the plasmid DNA that
you have isolated from colonies.

This is effect is commonly observed when sequencing influenza virus
isolates from patients. It will have nothing to do with the E. coli strain.
You can avoid it completely by using gene synthesis.

Darren


2012/1/24 Rubén Sánchez Eugenia ruben...@hotmail.com

 Dear everyone,

 I am trying to clone a viral protein in the E. Coli BSJ strain and i am
 having some problems.

 I start from the viral RNA carrying out a reverse transcription and PCR
 (RT-PCR) to obtain the protein cDNA. When I sequence this cDNA to check for
 mutations, there are no mutations. So the RT-PCR works fine.

 Then, I digest the cDNA and I ligate it with a pET plasmid to transform
 the E. Coli BSJ strain. I get recombinant colonies (checked by colony-PCR)
 but when I sequence them I get various mutations (aprox. 2 miss-sense) on
 the inserted cDNA. Furthermore, these mutations are different among
 different transformations and even among colonies of the same plate (in the
 same transformation).

 Maybe these mutations are produced by the cell (because of the lack of
 mutations in the cDNA) but these E. Coli clonning strains are supposed to
 be optimized to prevent the insertion of mutations. So I have no idea
 about what may be the problem.

 I hope you could help me. Thank you.

 Best regards,

You could also try Christian Biertuempfel's suggestion of *pDRAW32*: if it

 vector/plasmid map editing, making/visualizing vector maps, and aligning
 (small to medium size) DNA sequencing data? Preferably, it should not be too
 expensive and be able to write text files, readable by other programs.

 I am familiar with VectorNTI, which is great for vector visualization and
 editing; but I find it somewhat expensive. Sequencher seems good to quickly
 align DNA sequences (such as from DNA sequencing) with templates, but is not
 free. I have been using ApE for while for alignments, but aligning many
 sequences is more cumbersome than in Sequencher; I have not tested if
 Sequencher is good at visualizing and editing plasmid maps.

 Ideally, I would like to have a single program for both purposes (vector
 editing and DNA sequence comparison). Does something like that exist? What
 are the alternatives to above programs?

 Thank you in advance.

[ccp4bb] Off Topic: Web or e-tools for booking instrument time

2011-02-16 Thread Darren Hart
Hello,
Since we are now part of the Facebook Generation (or at least 10% of the
planet is), it seems there must be a better way of distributing time on our
various Aktas to an institute of scientists than our current system which
involves a race for the paper booking sheet every Thursday morning.
Inevitably people book in a speculative manner and time slots are not always
used due to problems in preparative steps etc. Bits of paper in different
buildings make it difficult to see who booked what and when.

Has anyone successfully implemented an electronic system, perhaps shared
through the cloud, that allows real time booking in a manner that can be
revised easily and has worked well? An electronic calendar (Google..) would
partially address this, but it seems some sort of social networking
site/tool might be better for negotiating instrument time, swapping
timeslots, reallocating unused time if the sample prep fails.

Any suggestions would be greatly appreciated. If governments can be toppled
through Facebook, I'm sure we can book our Aktas in a better way!

[ccp4bb] OT: Crystallisation compatible detergents

2009-03-24 Thread Darren Hart
Hello,
We can make a nice 1:1 complex between two proteins that then gradually
precipitates during storage at 4 degC. With 0.005% Tween-20 the complex is
stable and does not preciptate noticeably. We have used this in buffers to
measure the kinetics of binding by Biacore so it is clearly compatible with
functionality.

Is Tween-20 at this concentration compatible with crystallisation? Is it
worth giving a go, or a waste of time? Should we try and remove it, or
reprepare the complex in an alternative detergent?

If we need to try an alternative, what would people recommend?

Thanks in advance for your suggestions,
Darren

[ccp4bb] OT: VectorNTI alternatives - SUMMARY

2009-02-05 Thread Darren Hart

You could also try Christian Biertuempfel's suggestion of *pDRAW32*: if it
works under Wine on Linux, it should work under Wine (or the commercial
equivalent Codeweavers Crossover) on OS X as well.

Roger Dodd - *PlasmaDNA *which seems pretty good for the basics
http://research.med.helsinki.fi/plasmadna/ . It works under Mac OS X and
Windows... and probably Wine on Linux too.

Jann Sterxx - *Geneouis *also runs on OS X. From my experience (past two
years), the program works just fine. You can download the trial at
http://www.apple.com/downloads/macosx/math_science/index1.html (second
page).

Re: [ccp4bb] OT: VectorNTI alternatives

2009-01-30 Thread Darren Hart
Hello,
I spoke to Invitrogen (France) today and they said that, if asked, they
would provide a 2 month free license so that people could do exactly this
and recover their files.

The also said they would send me details on a simple procedure to extract
the data from a locked version which I will post on the bb.

They told me they have 100,000 users - so hardly a minor specialist
application! At €650-€4000 per license, that looks quite fruitful for them.

An earlier poster made the point that it is a good thing to pay for good
software. I agree and don't want to seem like a moaner, but I object to the
strategy employed here on this occasion. Hence my original post to find out
what the alternatives are.

 My license recently expired.  I had been running VectorNTI on my Mac
 through a Windows virtual machine.  When the license ran out, I was unable
 to export any of the sequences that I had created.  Now, if there was only a
 way to turn back time so that my computer thought it was still 2008 ... ehm
 ...  ;)

[ccp4bb] OT: VectorNTI alternatives

2009-01-28 Thread Darren Hart
Hello,
After several years of offering the molecular biology software VectorNTI
free to the academic community (their open access program) and building
up a huge user base, Invitrogen have suddenly announced that they will no
longer renew these free licences and the existing ones will be left to
expire within the year. There are heavy renewal fees for anyone wishing to
continue use of this software.

Can anyone recommend decent alternative PC compatible alternatives? Main
uses are construct and primer design, plus simple quick alignments,
sequence data analysis etc. The database structure for storing sequences
was pretty useful also.

Ideally free, otherwise reasonably priced. I've seen CLCbio and Geneious
have products, both free and paid. Any experience?

Thanks,
Darren

Re: [ccp4bb] OT: VectorNTI alternatives

2009-01-28 Thread Darren Hart
Hello,
Thanks for all the emails (only some of which reached the bb). It is clear
that I am not alone in feeling aggrieved by Invitrogen suddenly introducing
licence fees, having first persuaded us to put our files and time into their
free product over several years.

Once the thread goes quiet, I'll summarise the suggestions for everyone's
benefit. I've tried several packages today but it would be good if
suggestions were accompanied by brief strengths and weaknesses.

From a first view, there are a number of clunky programs that do the job.
And some that are really just viewers that are difficult to use for sequence
manipulation. As a lab with hundreds of constructs and primers in our
database, we also appreciate the file arrangement/storage as well as the
sequence analysis function.

Thanks
Darren

[ccp4bb] Workshop: Directed Evolution Approaches in Structural Biology

2007-12-12 Thread Darren Hart

Directed Evolution Approaches in Structural Biology
Wed 30th  Thu 31st January 2008 at EMBL Grenoble, France.
Funded by: SPINE2COMPLEXES  TEACH-SG (EU FP6)

Info  Register: www-db.embl.de/jss/EmblGroupsOrg/conf_91
See also: www.spine2.eu/SPINE2/meetings/index.jsp?m=28

A number of laboratories are now developing or using library-based 
strategies in combination with structural biology. This may be to 
overcome problems in the structure solution process (expression, 
crystallisation etc.) or to study/engineer proteins for structural and 
functional studies. We aim to strengthen links between these labs and 
provide training for scientists interested in this field.


Topics
1.  Library strategies for “difficult-to-express” proteins
2.  Scaffold proteins and binders as cocrystallisation chaperones
3.  Combinatorial approaches to protein complex definition and expression
4.  Structural studies of in vitro evolved proteins

·Colony filtration (CoFi).
·Combinatorial Domain Hunting (CDH).
·Efficient fragmentation, truncation  mutation approaches
·Robotics  truncation libraries.
·GFP solubility screening.
·Screening by FACS and fluorescent colony picking.
·DARPins  ribosome display.
·DNA shuffling/Oil-in-water emulsions.
·Use of display technologies
