Hi all, I am using an monoclonal antibody to test a membrane protein (tested appilication include Flow cyt and western blot). It was succsessfuly used in Immunocytochemistry (cell culture) before. However when I applied it in Immunohistochemistry (Frozen sections, human tissue), there was no signal at all (The fixation is the same). Is there so big difference between ICC and IHC-Fr? Is it my problem or the antibody's? Many thanks! Celia Chinese University of Hong Kong Hong Kong
