Hi Susan,

Here's a procedure for frozens I've used that works pretty well.   Hope this
helps,  Nancy

After cutting fix in a sol'n of 3 parts methanol to 1 part 37% formaldehyde
with 6 drops of glacial acetic acid added just before using for 3 -4 mins.
Then:
1. Rinse the slides in running water.
2, Stain with Mayer's hematoxylin for 3.5 min.
3. Rinse in running water for 2 min or until blue.
4. Rinse in 80% ethanol.
5. Counterstain in eosin for 15 sec.
6. Differentiate through 2 changes of 95% ethanol, dehydrate with 100%
ethanol and clear.
