[Histonet] Softening animal tissue

Mon Feb 12 05:57:20 CST 2007

Pam,

What is the dilution of glycerin (strength) that you use? I would be
interested in trying this out. Any other guidance such as how long do
you soak your blocks, etc would be helpful also. 

Thanks,
Diane

Hi all...
One of the things I've done for years is soak tissue with a dilute
glycerin. Not exactly sure why, but the cells do not blow up, nor is the
staining affected, neither routine nor immunos..Sections adhere to the
slides just fine. 
I'm at Evanston Northwestern Hospital in Evanston Illinois...we do some
work on animal tissue also and this has worked well for me. It also
works on decals, and very well on blood, such as bone marrow clots, as
well as lymph nodes. It also allows thinner sectioning. 
I haven't done any recent searches for the use of glycerin and some
people are hesitant, but I did see that it's suggested by Frieda Carson
and is a question in the ASCP Board of Registry practice exam text.

Pam,

What animal tissue are you using?  I recall learning from HistoNet a 
while back that rodent tissues should be processed for shorter periods 
(30 min. per solution and paraffin change compared to 60 min.) because 
of potential hardening issues. This is also noted in several mouse/rat 
or small animal processing schedules provided in the Animal Processing 
Manual published by the National Society for Histotechnology's 
Veterinary, Industry and Research Committee, edited by Gayle Callis and 
Diane Sterchi (along with many other helpful tips for non-human tissue 
handling!).  I think it (or an updated version) is still available from 
NSH (Gayle, Diane?).

Hi,
     If anyone has any replies to this please do it to the list (or
include
me as well) as I seem to be in a similar boat having recently accepted a
transfer (within the same company) to a research lab. I must admit to
some
trepidation about animal tissue not having much experience with it. My
experiences are primarily clinical. I've heard some stories of great
frustration about animal tx. I'm sure I can handle it but there is
always a
learning curve.

Thanks
Amos Brooks

I need to get some input on cutting animal tissue. I have always worked
in
 a
clinical setting and have recently moved into a research lab. I find
that
the
 tissue is very brittle and needs to be iced for an extremely amount of
time.
Can  any of you animal cutting histo techs please give me some advice on
what
type of  paraffin you are using and what processing schedule you are
using.
I
have  recently changed to Richard Allen type 9 paraffin and it seems to
have
helped  some. I would appreciate any advice you can give me.

Thanks,
Pam

   Spleen  makes  for  a sensitive iron control.  The amount of ir
sufficient, but not overwhelming.

Hello Histonet, 

I was wondering if anyone has experience with GPR58, G protein coupled
receptor (alias TAAR2, trace amine associated receptor 2) human antibody
from LifeSpan using Ventana. So far, I've had no luck on paraffin
sections. I will need to test the expression on human pancreas (paraffin
sections). I'm using human cerebelum as positive control, as it's
described in the literature to be expressed in this tissue. 

I've tested, CC1, CC2 and protease using DAB kit for the developing.
With CC2 I do lose mostly of my tissues, no sure if is a buffer batch
problem or if conditions are really strong for cerebellum tissue.

Any advice it will be really appreciate it. 
thanks a lot, 
Ana
