[Histonet] GI biopsies

Not that I know, but beware: not because the GI biopsies are small it means that they can be fixed for less time. The fixation mechanism with formalin (penetration → binding → cross linking = fixation) is independent of the size of the sample. It is a time related event dependent on the chemistry of the reaction and the temperature, but independent of the amount of formalin or the size of the tissue.

Is any one timing fixation for GI biopsies like  breast cores for GISTs to do IHC on ? If so , how long? Thanks.
