The TST 44 by Medite has a large number reagent stations giving it the ability to stain large numbers of slides from different staining protocols in a short period of time. 

There are 44 stations in the Medite TST 44, 6 of these are water stations, along with 4 load stations, 4 unload stations and 30 staining stations. This number of stations allows for the staining of slides with H&E and PAP simultaneously.

Depending upon your protocols, you will have reagent stations left over for other staining protocols.

Eg.
A standard H&E staining program may only require up to 13 stations. These would include two de-waxing, three re-hydrating, Haematoxylin, Eosin, blueing solution, three dehydrating and two clearing. 

A cytology PAP stain may only require up to 16 solutions. This allows for two initial dehydrating solutions, three stains, Haematoxylin, OG6 and EA50, a blueing solution, two 95% alcohol washes before the OG6 and two 95% alcohol washes between the OG6 and EA50 followed by four dehydrating alcohols and two clearing solutions.

We have a number of users in your exact situation, please fell free to contact me to discuss this further.

Hello David,

The procedure you are remembering is the generation of gold colloids for
the purpose of performing immunostaining on plastic sections for electron
microscopy.  And you are correct, the color of the scattered light is
indicative of the particle size.  Not absolute, since individual eyes
vary in color perception so much.  Actual size generated depends on the
conditions employed in manufacturing the good particles, which are  then
cleaned by ultracentrifugation prior to use.  The colloid itself is
generated by the protein coating (which can contain the primary
antibodies) which is applied to the particles.

Patsy was describing the technique for using the paraffin tape transfer
system on MMA blocks.  One needs to remove the tape with an aliphatic or

I just received tissue in agarose and I tried cutting a couple of them with
very little luck.  I have never worked with this before.  Is there a trick
to sectioning it?  Should it have been processed differently?  I didn't know
what was in the block until I embedded it.

Proper nomenclature of formaldehyde and paraformaldehyde fixatives for
histochemistry. Histochem J. 2002 Jun-Jul;34(6-7):365-7.

This paper is nice-reading and its helpfull to avoid discrepancy in

Dear Zarana,
     Some years ago I purchased a polyclonal goat anti-human Factor VIII (von Willebrand)
which cross-reacted with rabbit, from Incstar Corporation.  The staining with FFPE
sections was very satisfactory.  However, I have been unable to purchase more from
this company, and I would love to find a new supplier.

 Hello all, 

I'd like to use rack the brains of all you histonetters. Can anyone
recommend antibodies to CD31 and/or CD34 that can be used in rabbit models?
Or, can anyone recommend other antibodies for blood vessels that can be used
in rabbit models?  I'm having a hard time finding these.

I am currently considering purchasing a Sakura Automatic slide stainer- DRS 6000 (i think).  I would like to set this instrument up to stain both Histology and Cytology slides.  I understand the unit has only 27 resevoirs for reagents, but can any of the resevoirs be commonly used by both procedures?  Or, to get to the point- does anyone do this with their stainer and would they be willing to share the procedure?

What is the hardest paraffin on the market?  I've found Gold Standard
Peel-A-Way with a melting point of 62-64 degrees C.  Does anyone have
any comments about the Gold Standard paraffins?  Years ago, a lab used
some sort of additive to their paraffin for bone that made the block
yellow in color.  Does anyone know what that could have been.  I believe
it was something like picrotin?  Ring any bells?  Thanks, Sarah

Tissue Prep 2 is hard but its melting point is not that high, and check 
with Richard Allan - I think they have one also.

I think you were thinking of piccolyte, a resin that dissolves in the 
melted paraffin.  We add this to paraffin milleniums ago, before paraffin 
technology and additives improved.  It made the paraffin  supersticky plus 
it was a total pain to deal with, a huge mess.  I recall the company that 
made it was called Hercules Corp, I am not sure you can even get it 
anymore.  It come in huge bags and big chunks in the bag.

There is a publication on this resin in J of Histotechnology back a few 
years.  Personally, you should try to find one ready to go to save 
time.  Surgipath has a blue ribbon paraffin, check with them also.

The publication, Microscopy Today frequently has lpublications on this

How about not allowing frozen sections on lung for the diagnosis of
infectious diseases? TB, Pneumocystis, etc.

Do a touch prep for the fresh tissue, and stain the slide that way. Make
several slides, so can do H&E, Giemsa, GMS, Kinyoun, PASH, whatever is
needed. Fix and process the tissue used for the touch prep, for diagnosis on
a permanent section the next day.

Most of the time, the touch prep will reveal the micro-organisms. Once in a
great while, there is a false negative, which is picked up the next day on
the fixed processed block.

If it is explained to the surgeons that doing frozen sections on infectious
lung tissue puts the cryostat out of commission for the rest of the day, and
that no other surgeries, including all tumor cases, will have any FS done
for the rest of that day, they are usually willing to accept the results of
the touch preps.

Occasionally, an infectious lung will still slip through, but usually
because they thought the x-ray showed a tumor not an infection, or there is
infection with the tumor.

But there is no need to do a FS on an infectious case. Like you said, it
decommissions the cryostat, to say nothing of the potential biohazardous
risk the person doing the sectioning is in, if they accidentally cut
themselves.

You will need the support/backing of the pathologists. But they should
support you, knowing that the cryostat won't be available for the rest of
the day. (Even if they aren't worried about the risk to the sectioner.)

Lately we have done several frozen sections on lung cases that have turned

defrost them and decontaminate them Does anyone know of any decontamination
procedures that does  not require the total defrosting of the cryostat.

Thanks for your reply Gayle.  From the info you gave, I found piccolyte
on the Hercules web site.  Still looking for the J of H article. 
Wouldn't paraffin hardness be a factor of melting point, with the higher
melting point being the harder paraffin?   Thanks, Sarah

Yes we use GAL 3 for Thyroid tumours too, along with Cytokeratin 19.
Papillary Ca's are positive with CK19 and mostly negative with Gal 3

I have cut lots of agar blocks and used the normal tissue processing
schedules of whichever lab I worked in. I usually post fixed the agar block
in Neutral Buffered Formalin for a few hours to a day after embedding
depending upon how well fixed the sample was prior to embedding in the agar
and processing. I do think your client ought to have told you what was
embedded in the agarose else how do you know how much to trim or what the
orientation is? I have used this procedure to orientate isolated hair
follicles and flat intestine samples so that I could get sections of precise
areas, so it was essential to have all the available information about the
sample.

In difficult cases, I hand processed the agar blocks to paraffin, but this
should not be necessary if you have a process that is suited to the tissue
sample itself. I always used 2% w/v aqueous agar (Difco) and maintained it
at 55 to 60C in a waterbath to keep it molten. I made a mould suited to the
sample, e.g. a cut off syringe, pipetted a layer of agar into it and allowed
it to start gelling, I then layered on my sample so as to orientate it
correctly, then pipetted a few more drops of agar on top, taking care to
allow it to cool sufficiently to avoid "cooking" my sample. To achieve the
latter, I drew up some agar into a pastette and held it at room temperature
for a few seconds to allow it to cool, trial and error taught me how long to
do this. 

I have to say that I have used agar for both paraffin and frozen sectioning
successfully. My hand process went through 70% ethanol, 3 changes of
absolute ethanol and 1 of histoclear each step being 1 hour, then overnight
in histoclear, followed by a further histoclear of 1 hour, 2 changes of wax
in the wax oven for 1 hour then embed. This worked well for me. 

I hope this helps.
