RE: brain question
I think the problem is in the initial freezing of the brains. Ice crystals
will grow if the tissue is not frozen fast enough i.e. snap frozen in liquid

Subject: brain question
A research tech is having a problem.....she is doing stains on fresh frozen
brain that she recieves from a brain bank. The problem is ice-artifact on
her sections/stains. She told me that she recieves the brain at -70 and then
cuts them on a cryostat at -20. Any suggestions....I only work with fixed
brain in parrafin.
