One person's opinion
It depends on the application for me, but generally, if morphology is important, then I fix them right away.

postfixation or air dry

Hi Histonet

I have seen two basic camps regarding the treatment of frozen sections
once the section hits the slide - One camp fixes immediately and one
camp leaves the section to air dry, sometimes overnight.  I realize that
there is likely not a "right" answer, but are there advantages to one
process method over another? I'm in the midst of trying out both
processes and evaluating myself, but in the meantime I'd like to hear
feedback from the community.
