Dear Dr. Miyagishima,

You do not perform pretreatment such as antigen retrieval or enzyme
digestion on frozen tissue.  Pretreatment is generally used to unmask tissue
due to the affects of the fixative such as formalin.  Frozen tissue would be
destroyed by heating.

I was suggested to do HEAT ANTIGEN RETRIEVAL for frozen tissue sample.

Does it work for frozen tissue, too?  Do I have to do some modification
on protocol?  I am planning to cover slides with 10 mM sodium citrate
buffer, pH 6.0 and put into micorwave for 10 min.
