Michelle,
	Since you are in Anchorage, contact Dr. Probst at the State Medical

you need.

Subject: Aqueous mounting medium


Dear Histonetters
Has anybody a good suggestion (brand name, catalogue number) for an aqueous
mounting medium that  i) dries completely and reasonably fast (-> slides to
be
archived);  ii) doesn't start with lots of tiny air bubbles that have no
other
purpose than to grow larger with time;  iii) is easily applied, i.e. no
first
layer, let dry oN, second layer etc. (our pathologists don't like to wait
...);  iv) doesn't cost a fortune? We've been using Aquatex from Merck and
Aquamount Gurr from BDH with our immunohistochemistry slides (alkaline
phosphatase - new fuchsin -> better contrast with aqueous mounting medium
than
after clearing and resin-based mounting medium) for quite a while but never
were really happy with these products, in particular because of their
inherent
tendency to form bubbles. Any suggestions to make our lab life bubble-free
are
welcome! If you have experience with aqueous mounting media on automated
coverslippers, don't hesitate to let me know. Thanks a lot.

Give Biomeda's Crystalmount or Shandon's Aquaperm a try. They work pretty
well. Just apply over the sections and let it dry without coverslip. After
it has dried, you can coverslip the sections with an organic solvent based
resin for permanent storage. In my hands, these are the only aqueous
mounting media that come close to organic resins in terms of refractive
index and thus section transparency. I must however say that they are too
pricey in my opinion.
As to the use of automated coverslippers with these media, I have no
experience.

Subject: staining old tissue

Hi.  I've got some mouse spinal cord tissue that has been sitting on slides
in a freezer for two years.  I need to stain it for oligodendricytes with a
cc-1 antibody.  The procedure that was prepared workes beautifully on
tissue that has been UNCUT in a freezer for a long time, and was cut only
recently to practice for this stain.  However, when the precut old tissue
(the important stuff) is used with the same procedure, the background
staining is terribly high.  Oh yeah, it's developed with DAB.  The
oligodendricytes are too light to be seen clearly against the background
stain, making them uncountable.  Our head histotech thinks its due to
freezer burn, or something similar to it. Does anyone have any ideas as to
how I can salvage the rest of this tissue?

Thanks,

Sharon,

The quick answer to that question is Leica 800-248-0123.  The long
answer may explain why I feel that it is doubtfull if they will have AO
(American Optical) parts available.  They have gone through several name
changes (AO Reichert, Reichert-Jung, Cambridge Inst., and Leica) and one
major location change, from Buffalo, NY to Chicago, IL.  I left the
company shortly after Cambridge Inst.'s took over and at that time there
were still some parts available in Buffalo for the AO Spencer microtomes
but not a lot.  That has been some years ago so there is no telling
what, if any, of the older parts are still available.

Jo Ann:

The registry exam is different for each person.   Since the exam is computer

administered, it can easily determine each person's ability.  The first
question given will be of moderate difficulty.  If you get it right, the
next
question will be more difficult, but if you get it wrong the next question
will be easier.  Thus each question is determined by your response on the
previous question.  There is a preset pass/fail point, and you must end up
above this point to pass the exam.  That is a very simplistic answer to your

question, but hopefully will explain why each person gets a different exam,
unless two people respond to all questions in exactly the same manner.

    I have had great success with antibodies to TH and DBH from Eugene Tech.
on
formalin-fixed frozen or cryostat sections of rat or mouse tissues. I use
the
Vector or Vector Elite kits for detection.
    My impression is that there are several (or more) companies supplying
good
antibodies to these enzymes.

	Dear Rebecca,

	One of the great problems with precutting & storing tissue is that
you
expose the tissue to oxidation (sp) & reduction reactions with the
surrounding environment.  This is also true of blocks.  However, by the
time you have trimmed the surface of a block you are into the unaffected
tissue.  While there are many people who can report that they have stored
unstained slides forever without detrimental effect, it depends on the
staining.  H&E no problem, many histochemical & some immuno staining - no
problem.  BUT, for the really important stuff - big problems.  In some
cases the chemical reactions that have taken place can be reversed, ie
antgen retrieval (if your lucky).  I was taught to always store blocks, &
only store unstained slides for short periods (weeks to months depending on
what they were for).  Refrigeration slows chemical reactions it doesn't
prevent them.  If you must store unstained slides & must get good results
from them I can only suggest placing them immediately in a container filled
with nitrogen gas, temperature of storage - probably cold.
	Long term storage of tissue in fixative creates similar problems.

Does anybody know of a CGRP antibody directed to the N-terminus?

Thanks

Subject: RE: HT Practical

michelle,
using an automated coverslipper is ok as long as it uses GLASS coverslips.
the instructions specifically state that coverglasses must be used....the
tape-type are not acceptable.  i know a couple of students who had their
slides rejected outright because of just this misunderstanding.
good luck,
carrie kyle-byrne

Hi,
    In regards to the idea of using an automatic coverslipper for your HT
practical exam. My question is WHY would you want to trust an automatic
coverslipper with your slides. Try for perfection not quantity.

Subject: AO-820, repairs?

My last inquiry about an AO 820 repair ended up with IMEB used equipment
dealer, who had these instruments (a bunch, if I recall) sitting in a back
room.  I don't think parts are made anymore, a repair can be done,
not cheap!and a considerable down payment on a new microtome!) and I think
parts may be scavenged off the older machines in some cases.  I don't think
Leica even bothers with them anymore.      This was about
to happen with my one good 820 and an old 820 no longer usable on my shelf,
I opted for a new microtome.  Was difficult to give up the old workhorse,
but I had to put it out to pasture for a new thoroughbred!

Subject: Re: AO-820 & Spencer 880s

	Dear Gayle,

	I used AO's at the Uni of Tasmania & occassionally still find them
hard at
work in small/old labs.  The Anatomy Dept at the Uni of Sydney still wheels
them out (& Spencers too) for students.

	But in a lab where I worked about 2 years ago they had a beautiful
black
Spencer-880.  The Spencer cut rings around the (newer) AO-820 that sat
beside it on the bench.  As I re-equipped the lab both of the microtomes
were replaced with (2nd hand) Leica 1512s.  The Spencer now has a home in
my shed as part of a collection of early microtomes, microscopes & other
histological sundries (they take up less room than vintage Buicks).

	Of course the old microtomes had plenty of crosses against them.
They are
heavy to shift & often stiff (in comparison to modern machines) to operate.
 Modern safety devices were missing too (& motors!).  I don't always like
the modern microtomes with their light weight (ir)replacable innards, but
my arm does not ache as much when I have to do some sectioning.

	 Regards

	Rob W.
