[Histonet] Optimal Fixative

[Geoff McAuliffe]

Hi Melissa:

    Tissue that thick must be sliced into 3-5 mm slices to get adequate 
fixation in the center. While an alcohol-based fixative such as 
formalin-alcohol-acetic acid will penetrate faster than buffered 
formalin, your tissue is too thick for adequate fixation in the center 
without slicing it into smaller pieces.
