Immunocytochemical analysis of FasL expression in human melanoma cells. FasL expression in three representative melanoma lines (Me15392, 501mel, and Me30966, in A, B, and C, respectively), from a panel of 10 tested, is shown. Note (i) the striking localization of the FasL staining on well-defined cytoplasmic vesicles and (ii) the differential quantitative expression among the three cell lines. Immunophenotyping of fixed cells was performed using the PAP method. AEC was used as chromogen and Mayer's haematoxylin for the counterstaining. Original magnification: 2,500×.
