[Histonet] Used microtome

2010-01-11 Thread Massimo
Hi all,

I am an amateur naturalist, and I'm looking for an used microtome, but working, 
even on old model, to be used for histological sections of samples included in 
paraffin.
Please can anyone give me useful directions where to find it?

Thank you all for you help,

Re: [Histonet] shipping slides, elementary question

2010-01-11 Thread Jan Shivers
I pack slides in 100-slide plastic boxes, with gauze sponges laid inside the 
boxes on top of slide edges to ensure that they don't jiggle around inside 
the box.  Boxes are taped shut, then packed inside a cardboard box with 
plenty of room for packing peanuts or bubble wrap.  Never have had a 
problem.

Subject: [Histonet] shipping slides, elementary question



Happy Friday everyone,

I have a very basic question about shipping slides (mouse tissue, 
non-biohaz). I am planning to ship a bunch to a collaborator, on the order 
of a few hundred. I have black hinged cardboard/wood 100-slide boxes, 
similar to



https://www.vwrsp.com/catalog/product/index.cgi?catalog_number=48452-001inE=1highlight=48452-001

will these be sufficient for shipping (provided I ensure they stay closed 
during transit) to avoid breakage? I have slide mailers, but they only 
hold a few slides. I will do that if I need to (it would be a whole lot of 
packaging and labeling though...), but don't want to just send a giant box 
and have them all broken on the other end. Maybe there's another 
alternative? I'm sure someone on histonet has done this before :)


Thanks in advance for the advice.

Sincerely,

Try looking for microtome on e-bay.  There is a company there that sells a

Re: [Histonet] Used microtome

2010-01-11 Thread Michael Folsom
Hi:

There are a couple of sources besides the makes and vendors but as
always it is buyer beware.

eBay - you can go to www.ebay.com and do a search for microtome, right
now they have several for sale.  The good thing about eBay is the
shipping is often reasonable and you can get a good deal.  The bad news
is that things can be way overpriced and the sellers usually don't know
what they are selling and expensive parts can be missing so you really
need to know what you are doing before you buy.

GoIndustry - DoveBid at http://www.go-dove.com/default.asp
This is a very different deal than eBay.  Here you are buying products
that are surplus when a company closes or gets rid of excess equipment.
Please note microtomes are used in ares outside of BioMedical.  For
example companies that fabricate plastic often use microtomes for
testing purposes so you can find them in unexpected places.  Problem
is that with DoveBid shipping is totally on you - unless you are near
the auction site you will need to pay a shipper to pick the item up,
pack it up and ship it to you.  This can easily cost $300 for a
microtome so you need to know what your are doing plus you  pay a
buyer's premium which can range for 16% to 18%.  I find equipment on
DoveBid is often newer and looks to be in better shape than eBay but it
costs lots more.  Right now DoveBid lists 5 different microtomes:

Shandon Finesse ME
Leica RM2135
Biocut 2035
Reicheit-Jung 2050
Leica RM2155
Leica RM2025

My advice is to take your time and know what you are doing -

Good luck in your search.

Does anyone have a good source to get rid of equipment that is still
good and maybe our lab can make a few bucks in the process?  The last
time I did this I was told the processor and stainer I gave away would
be going to some charity and of course it did not I found out later.
These items are off the books, maybe in need of a small repair.  We have
no room and the equipment is just been depreciated such that if we can
get a credit or something for our lab as a trade in.  Specifically we
have an RMS microtome in perfect condition used for 6 months and put
away.  The other is a Leica Embedder that does everyting but dispense
paraffin.  We were using a separate paraffin dispenser and it was fine,
but finally got another embedder.  Anyway, vendors welcome.

Hi, 



I have seen several answer suggesting eBay.  Before you go there you need to 
know what kind of kinives you be using so you get teh correct knife blade 
holder.  Are you using disposable knives?  If so are they high or low profile? 
Are you planning on sharpening solid knives?  What kind of block holder do you 
need?  Are you embedding in cassettes or with forms?  All of these questions 
need to be answered before you buy or you could end up with something you can 
not use or is unusable in your hands.  If you know all these answers eBay could 
be a good way to go.  I would try to talk to some of the used equipment people 
and be sure you are going in the correct direction.

[Histonet] Podoplanin D2-40

2010-01-11 Thread Carol Bryant
I am using Podoplanin, D2-40 on cytology cases.  We use a mesothelioma tissue 
for the control and the control performs appropriately, but our cell blocks are 
staining very faintly.  We stain on the Ventana Benchmark using the following 
protocol:  Depar, standard CC1, antibody for 32 min, amplify selected, 
counterstain, and post counterstain.   I am thinking the standard CC1 may be 
too harsh for the cell blocks and maybe cutting it back to mild treatment may 
help. Any other suggestions to boost the staining intensity of the podoplanin 
on the cell blocks?
Thank you in advance for your thoughts and input.

Cut very thin (about 2 µm) and let the sections expand well before taking them 
from the water bath.
After that shake them and put the slides vertical on their smaller side (1 
inch) for 15 minutes.
Take to the oven at 60ºC for 10 minutes and proceed as usual.
You could also buy a Kurabo S200 sectioning robot that has been found to be 
specially useful for the type of work you are describing (better than manual 
sectioning).

Re: [Histonet] Podoplanin D2-40

Are your fluids initially fixed in alcohol before the cell block is prepared?  
If so, that can reduce immunoreactivity for some proteins.  If you can, I would 
recommend trying to decrease the sensitivity of your antigen retrieval.  I am a 
strong proponent of Personalized antigen retrieval (adjusting the retrieval 
based on the type of specimen, fixation, and the length of fixation).  I do not 
have any experience with Ventana's instruments, but on our Bond Max and Bond 
III instruments, we can adjust the antigen retrieval very easily (low vs. high 
pH and the time).

I am using Podoplanin, D2-40 on cytology cases.  We use a mesothelioma tissue 
for the control and the control performs appropriately, but our cell blocks are 
staining very faintly.  We stain on the Ventana Benchmark using the following 
protocol:  Depar, standard CC1, antibody for 32 min, amplify selected, 
counterstain, and post counterstain.   I am thinking the standard CC1 may be 
too harsh for the cell blocks and maybe cutting it back to mild treatment may 
help. Any other suggestions to boost the staining intensity of the podoplanin 
on the cell blocks?
Thank you in advance for your thoughts and input.
