Hello!
What is the best way to fix intestinal samples in order to preserve the
mucus (and the embedded bacteria)?
I was recommended Carnoy's, but are there any alternatives... perhaps
without chloroform?
With best regards,

Hi all
Is anyone of you using a an alternative for the DAKO-ARK kit. In my opinion it
is good, but rather expensive.

Hallo,
are there any experiences in embedding of insects in historesin (GMA
or Glycolmethacrylat (Technovit 7100))? I have tried Technovit after
fixing in Formaldehyd with poor results. The specimen tends to fail
out of the block. There is no connection between the cuticula

Oh, sorry, I forgot one additional question regarding Carnoy's: in the
protocols I found, Carnoy's is prepared using DRY methanol. Sorry for my
ignorance, but does this mean that methanol has to be specifically
treated to remove any hygroscopic etc water? Note that this is
specifically
First of all, this sounds like a Damien Laudier question. Damien, I hope you
can help this guy.
Secondly, do you have to use plastic embedding? I was successful with paraffin
embedding. I was able to section various small insects and also bees. It takes
some patience and soaking in mollifex or
I already contacted them about this, but I thought that all of you might
be faster:
Would anyone happen to know if these dyes, if used to mark mouse
bone/tissue around said bone at necropsy, would survive decalcification?
We're trying to facilitate orientation of OA mouse knees during embedding
Hallo, Andi G.
Thanks for your reply. Normally I use paraffine for embedding insects
after dehydration and using N Butylalkohol with sucess. In my opinion
it is absolutly necessary to avoid any rests of water and to cut cool.
But this technique is limited to sections of 3-4

Hey there, does anyone have a good method to de-stain Fast green? The slides
need to be re-stained with HE.
Thanks.

To all you math whiz out there, please help with this math dilution.
If my Ab conc is 1.56 mg/mL and they want to optimize to 0.8 ug/mL, what
dilution should I use?

Here is how I would approach the problem. We would use the basic mathematical
equation of the following (in order for this to work you need to keep the
units the same)
V1 x C1 = V2 x C2
V1 - volume of stock solution needed - this is what you are solving for
C1 - concentration of

The waste alcohol is disposed of with the rest of our waste chemicals in a 55
gallon drum that picked is up by a licensed waste hauler. The paraffin is also
picked up.

I will add another bit of information. That final antibody protein
concentration is very low. Most of our antibodies (around 60 to 70%) will be
in the range of 1 to 10 ug/ml. We do have some antibodies that can have some
very low protein concentration though such as neurofilament.
Hi Liz,
Wouldn't you dilute in 999.5ul of diluent, not .5. 1ml=1000ul
Otherwise I got the same answer...

When I solve your equation V1 X 1560 ug/ml = 10ml X 0.8 ug/ml I get .005 ml.
Therefore the dilution would be closer to 1:2000. I would usually divide the
1560 ug/ml by 0.8 ug/ml and get 1950 therefore 1:1950 would be more accurate .

We are currently using Numeric for the specimen (or part) and Alpha for the
block. I don't like it; we frequently have 1Z blocks for large CA
resections! I would like to change this going forward.

We do Alpha numeric so A1,A2 but our samples also get barcodes so we have a
barcode ID that picks up whatever you designate it to and it is AAA001234
(designating a block) the slides then become AAA001234 0001, AAA001234 0002
etc. ties it back to the block and uniquely identified (called

We use a numeric for the case number starting with the year 14-SR- and an
alpha and number for blocs with the case. A1, A2, A3 so it looks like

designations as needed. Last week we had one surgical case with A through

Hello Histonetters,
how will we verify the thickness of a paraffin section in a slide. Do

but one of our reveiwers does not believed that we are cutting
Here's how I approach this problem.
Convert all concentrations into the same units. I prefer to use whichever the
final concentration unit is, so it looks like this:
1.56 mg/ml = 1560 ug/ml
You have 1560 ug/ml and you need 0.8 ug/ml
Divide 1560 by 0.8 = 1950. So your final dilution is 1:1950.
