[Histonet] Under-Decal'd tissue

Trisha - I swear by RDO, manufactured by Apex Engineering Products Corporation, Aurora, IL. The active ingredient is hydrochloric acid. If a block still contains calcification after either preliminary decalcification or if discovered after processing/facing, I drop the block into a small beaker with RDO and leave it for from 15-30 minutes (depending upon bone density). I've routinely used RDO for years on normal bony blocks, trephines, bone bx's, etc. and it works amazingly well. It is NOT, however, for LONG-TERM decalcification (i.e., overnight) because it works so well that it may render the bone devoid of any detail if left too long. The RDO must be washed off the block with a good dose of water before cutting, as the acid will discolor your knife holder.
Their number is 800-451-6291 or you can contact them at www.rdo-apex.com.

Does anyone out there have a good way to stain 2"x3" glass slides (whole-mount prostates) using a Sakura stainer? I have a 2000 and 601 model and have tried adapting the rack so I can stain 4 slides at a time, but it's so inefficient. Any ideas?

Hello!
We want to implement a database for specimens we receive in our lab.
We would use this database starting with logging in specimens and ending
with archiving of specimens. It would be used to track when various
steps
(gross photos, processing, staining, etc) have occurred and by whom.
We do want a system that is user friendly.
Any suggestions or advice?
Thanks for the help.....

Years ago, I think the Shandon stainer had a rack to accomodate the larger
slides, maybe Sakura needs to do this too. Otherwise, and we still do it
now - hand staining, and can do either 20 or 30 at a time - kinda old
fashioned but very efficient.

Dear histonetters,
Thanks a lot for all your tips!
One further question. When doing a control immunohistochemical procedure
omitting the primary antibody I guess that if I have not blocked the
endogenous peroxidase activity properly I should get staining. Isnt'it? If
in case I do not get any stain may I understand that the endogenous
activity is not a real problem?
I am working with free floating sections, polyclonal antibody, ABC, DAB.
Thanks once and again

Hello,
Has anyone had a problem on their negative controls having heavy
brown staining that looks like real DAB staining on negative mouse and
Rabbit controls that were retirieved using heat but the negative
control that used only protease treatment was very clean. I did a lot
of IHCs on adrenal mass tissue and my Rabbit and Mouse negatives look
like they have positive staining. H2O2 treatment did not correct the
problem, I also used the Avidin Biotin block. Anymore suggestions?
Thank you.
Josie

Dear Histonetters:
I got an email from the marketing director for Visual Histology and he wanted to know if it was ok to put a message out on Histonet about it. I thought it looked like something interesting so here are his comments.....
I want to make you aware of a relatively new website that provides some valuable free resources for histology teachers and students. The website is
www.VisualHistology.com and anyone who registers with the site can download
the Visual Histology Atlas (a 285 page comprehensive histology textbook from
Moran and Rowley) and also get free access to a 30-minute video tutorial
called "The Cell." The site also sells access to the complete Visual
Histology video tutorial series (26 titles) through a premium membership.
To learn more, visit: www.VisualHistology.com
If you have questions please inquire at the website as I haven't had any personal experience with these products.
Thanks

I am having a problem getting my CD31 to work. The protocol was for an

work well for a while but once again, I'm having problems with it. Any

Something a "tad" new for me here. I've never sectioned 4%Para liver infiltrated with 30% sucrose. They sectioned well but the slide appear to be loaded with what appears to be folds throughout. Not what I routinely see on regular unfixed FS. Is this normal for fixed sucrose infiltrated sections. Are there any special techniques when dealing with this special tissue.

I'm wondering how anyone could embed in a black tar kind of paraffin. I'm
guessing that this researcher doesn't have much experience in histology.
How would this help them?

Orlando Florida allows it. A few of the large cities are equipped to
handle formalin in the system. You have to contact the municipal water
system people to see if they are set up to handle the formalin and receive
written confirmation for your records (and the inspectors) before you start
dumping ANY of it in the sink.
We just started recycling ours with a Creative Waste Solutions,Inc
Formalin recycler (rex <@t> cwsincorp.com) and have been very pleased with the
results. How and why it works I leave to him to explain, but it does.

sink?
Hi Histonetters,
Does anyone know of any regulations as to the amount of formalin one can
pour down the sink? I am in Texas.
Thank you.

At any given temperature, tissues infiltrated with sucrose tend to be softer
and less completely frozen than similar tissues without sucrose (and 30% is
a very high level of sucrose), and therefore they compress and wrinkle more.
Try cutting them at a colder temperature than you would normally use for
liver. That will probably help produce flatter sections with less
wrinkling.

Is there anything that can be done for under decalcified bone after it has
been processed?

OPTION 1: "redecal" Melt the paraffin block, put the tissue in a cassette
as you would a fresh piece of tissue to process. Drop it in xylene for 15
minutes x2, then 100% abs. alcohol x2, 95% abs. alcohol. Wash in water and
drop back into the decal. Process when soft.
OPTION 2: "surface decal" Pour some decal solution into a small container
or Petri dish and put the faced block face-down in the solution. Let soak
for 15 min (time depends on hardness of the tissue) put on ice and try to
section. Only the surface will be decaled so try to take a section off the
surface.

Sometimes you can get a decent section by pressing gauze soaked with decal
fluid on the face of the block for a couple of minutes (wear gloves), then
taking the first section off the face. Or you may get a few successive
sections by soaking the faced block in decal fluid for 15 to 30 minutes,
then chilling the block on the cold tray and cutting right off the face.
However, if you are going to be doing any substantial amount of work with
that block, probably the best approach is to reverse process it, decal it
properly, and reprocess it. Remove the paraffin by soaking in xylene or
whatever clearing agent you use, remove the xylene with absolute alcohol,
bring the specimen down to water, then decal it, wash it and process it as
usual. If you want you can place it in formalin overnight once it reaches
the water stage, to ensure the best possible fixation before decalcifying
it. Since most tissue processors won't run the stations in reverse order,
you'll probably have to do the reverse processing by hand, in a beaker or
flask. If the tissue was well fixed initially, it should withstand this
treatment with little if any noticeable harm.

Hi everyone!
I'm doing a project on different staining methods for H. pylori in gastric
biopsies, and just out of interest really wondered which special stains
different labs routinely use for this purpose. My lab uses the Modified Giemsa.
Thanks

We use the Wharton Stary method.... you can also use an Alcian Yellow
Stain... there's another called the Toluidine Method I believe...
Hope this helps...
