A light positivity seen in exocrine cell cytoplasm: specific?
In intense positivity is seen in a small number of Islet cells.
I do not know if this is specific as the images I have seen from HPA/published papers are not consistent…or am I wrong?
Should be diluted further.
Excellent positivity for platelets and megakaryocytes.
Immunopositive platelets are seen in the red pulp.
Unfixed frozen section of mouse lung. Sections cut at 10 microns, mounted onto slides and dried overnight in a fumehood “on”.

Lower image: Acetone – fixed for 15 mins at RT.
Note the FIF in the upper image. I am surprised that there is FIF even with such a short fixation time.
Arrowheads indicate negative Purkinje cells.
