Fas Ligand Antibody (Clone I-6060) Host:Mouse Antibody Type:Monoclonal Species Reactivity:Human Application:Western blot, Immunoprecipitation, Immunohistochemistry Western blotting (1-4 μg/ml), immunoprecipitation, and Immunohistochemistry. However, the optimal conditions should be determined individually. HeLa cell lysate can be used as a positive control and an approximately 40 kDa band should be detected by Western blotting.
