Laura,
For H&E's on GMA embedded tissue, you stain right thru the plastic, it is
water permeable and cannot be removed, there fore it will often take a more
concentrated and or longer incubation times to stain. I use Gill's III
hematoxylin for GMA sections for 10 min., you can use alcoholic eosin but
beware that alcohol with any water in it tends to lift the GMA section off
the slide. Here is what I do:
Gill's #3 10 min.
Tap wash for 1 min.
Dip in ammonia water to blue (10 dips)
Tap wash for 5 min.
I then airdry the sections before going to alcoholic eosin
Alcoholic eosin (right now I am using SurgiPath) 60 dips then quickly 5 dips
in 95% alcohol, then to 100% and xylene (once past the alcohol with water
the sections are fine. An alternative is to use aqueous eosin, rinse with
water, airdry and then dip one at a time in xylene and coverslip.
For all other stains that end in water rinses I airdry GMA sections and then
coverslip without going thru graded alcohols to dehydrate.
Hopes this helps,
Patsy

Subject: [Histonet] Staining coral tissues embedded in resin
Hi everyone,
I am new to the forum. I am working on coral tissues embedded in
Immunobed resin and paraffin. We would like to stain both with H&E
and Azure II /Basic Fuchsin. I have never tried staining plastic with
H&E. Any suggestions or comments would be great! Since corals have a
calcium carbonate skeleton, the tissues were decalcified in a EDTA
solution.

>> Hello,
>> Recently we bought a sakura slide writer that uses ink to print. The
>> only problem I have found with the ink is if you put labels over the
>> print and then try to remove the label to verify a number error, or
>> something like that, the ink will actually come off with the
>> label. If
>> you can read upside down you can still verify the number. I did run
>> this ink thru a battery of chemicals including straight formic acid
>> for

>> buying a Sakura slide write as it has a very unfriendly Access based
>> program and the writer does not work with charged slides. This has
>> been
>> verified by me and an independent engineer sent to look at this
>> issue.
>> I do use a TBS cassette writer and love that so if I can get my
>> sakura
>> sent back I will be looking at TBS's slide writer too.
