Dear Dorothy,
I am from France and this is the first time I can read that we can no longer
user alcoholc fixatives on breast tissue. Is it a regulatory rule ?
Thanks for your help
Kind regards

Christine,



My understanding is that other vendors do have something similar to the
cocktail, but they only contain 2 of the antibodies and the third has to be
added at another step, not completely sure on that.?



But I do use the BioCare PIN-4 cocktail and have been doing so for 3 years
now with no complaints; I?have done?a few thousands of these so far.? I use
their Mach 2 Double Stain detection system with the cocktail and it works
like a beaut.

Can anybody tell me if there is another company besides Biocare that offers
an antibody cocktail with P504S, HMW CK, and p63? Does anybody use the
Biocare antibody detection system? I'd appreciate some feedback.
Thanks.

"We are currently retrieving animal tissue in a pressure cooker with a

negative controls whereas if we did not retrieve them, there is none.  We
were staining for KI-67 which is a nuclear stain. I am using a tonsil for
the control. The negative control showed some sporatic cytoplasmic staining
on the Universal negative control from biocare as well as deionized water.
Since then we have taken the temperature down to 115 degrees and increased
the time to 25 minutes.  It seems to have decreased the cytoplasmic staining
but there is still some lingering.  Anyone out there have any ideas??? I'm
sure there is a better protocol for retrieving animal tissues. It has to be
a time and temperature thing!"

MaryAnn, you don't mention what type of animal you are staining, and what
your IHC protocol looks like.

I would never use a universal negative control  when doing immunostaining on
animals. Use only the Igs from the species the primary antibody was made in.
If you are using a monoclonal mouse KI-67, you would need to use non-immune
mouse IgGs of the same isotype of your primary antibody. If your antibody is
a rabbit polyclonal or monoclonal, you'd need to use non-immune rabbit IgG.
It's also important that you match the Ig concentration fo the non-immune
(negative) control to the Ig concentration of your primary antibody. If you
are using pre-diluted antibodies, you may be using different Ig
concentrations.

Try an additional run to see if your detection system is causing the
staining. Run a tonsil, and do the pressure cooker retrieval as usual,
however and omit the primary antibody, using only diluent or buffer in the
incubation. Then continue your IHC protocol as usual. If there is still some
background/non-specific staining, it's due to your detection system (kit?)
and not to the antibody or negative control reagent.

Additionally, I never use a universal reagent for detection. Making sure
your antibody reactions are appropriate are difficult enough without
throwing in additional animal species you don't need.

If you still have specific questions, don't hesitate to contact me off-list
and I'll be happy to take a look at your protocol and make some
recommendations.

Good luck!

Now that we can no longer use alcoholic fixatives on breast tissue, is there
anyone out there that is putting a slight temperature on the reagents on the
processor to enhance fixation and dehydration?  I have thought of using
stronger alcohol grades and an extra xylene, which would help in the
dehydration of the lipids.  This would be a dedeicated processor for fatty
tissue types only.  What is everyone's thoughts and thanks for all input!

Hi Christine,

We make up our own antibody cocktail of 34_E12 (DAKO dilution 1:150) and P63
(DAKO 1:400) and stain the section with this cocktail with a Polymer
peroxidise detection system (DAB).(Heat retrieval in a high pH retrieval
solution for 20 min at 100 C.

The stained slides are washed and darkened using a copper sulphate solution.
Placed in a buffer wash and then stained for the second time with P504S
(AMACR/Racemase) at a dilution of 1:150 with a Polymer Alkaline Phosphatase
detection system (Fast Red).
We do this all on the BondMax Immunostainer.
We have been doing this for over 6 months now and did it this way because we
already had all the concentrated antibodies.
Proper fixation is vital.

Hope this helps.

Hello everyone,
I have some questions regarding microtomy. 
We place our blocks face down on ice. The problem is that some tissues take
a very long time before they are ready to be cut(some more than 6 hours).
For some tissues like kidney samples (mouse tissue) we have been using
glycerol on the ice. This does seem to cut down on the time needed. My
question is which other tissues can I use this technique on? Do you have any
other suggestions for how to get the tissue hydrated for cutting?

Eva:
  This type of problem (requiring ice, glycerol, and others) to allow
sectioning usually stem from either a fixing or processing defficiency. I
suggest you to check your fixing times and processing protocols or you will
keep having this type of difficulties.
  Tissues (any type) properly infiltrated (after adequate
fixation/processing) do not need anything but a light cooling to allow
ribbons to be taken.

Eva,

It sounds as though you are processing your tissues too long, and too much 
water is being removed (over dehydration.)   In general, a properly 
processed mouse tissue after a short schedule will need a bit of a water 
soak, but not for 6 hours.  Another trick is try room temperature or even 
warm water for a few minutes, then go to ice water, and be careful to NOT 
cut away what you have soaked - be careful to reapproach the blade in order 
to cut the sections.  Some people have suggested floating blocks face down 
on a waterbath for a very short time.

if you post your processing schedule, Histonetters can help solve some of 
this problem.

We've been using a Giemsa stain for our H. pylori cases without a control
tissue.  It has come to my attention that this may not be good practice.  I
was under the impression that the Giemsa stain had an internal control.  Is
anyone else using a this stain for H. pylori?  Are you running a tissue
control with it?

Slight correction.  The Xpress microwave tissue processor does not require a
special type of cassette.  The AutoTEC does, and it can be used on the
Xpress or in a traditional processor.  But the Xpress can use the same type
of plastic cassette used in any traditional processor.

I use both machines.  You can use the AutoTEC cassette on any type of
processor (including the Xpress) and you do not have to use the AutoTEC and
the Xpress both.  They can be used independently.

Giemsa, as any other stain, is just that, a stain, and stains do not
(cannot) have "internal controls".
  As with any other HC procedure you have to use a positive control along
with your tissue.
  To completely demonstrate that your Giemsa procedure worked as expected,
you coul use a blood smear or an appendix section as controls. That will
depend on your pathologist's whims.

Sorry Rene, on this occasion I can't agree.
Giemsa is not on this occasion being used to bring out granules as it would
in it's normal use as a blood/marrow stain. It is just used as a simple
quick stain, which will pick up Helicobacter inter alia.
If the tissue is blue, it has worked, at least to the extent it needs to
have done for this purpose.

I was referring at the fact that IF some coloration took place (of any kind)
the procedure worked, and there was a staining. I was not referring to stain
specificity.

Rene,
Are you saying a histochemical stain for an organism (Helicobactor, AFB,
spirochetes, etc) must have a positive control with which I'd agree?  But
are you saying that for "any" HC stain like elastic, trichrome, PAS, alcian
blue, etc that internal controls don't (cannot) even exist?

No.
The tissue can still be blue even if the organism isn't there.

BTW, has anyone ever seen a Giemsa that doesn't stain? I can't really
