FADD Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat, monkey Application:Western blot, Immunoprecipitation Western blot analysis (0.5-4 μg/ml)and can also be used in immunoprecipitation. However, the optimal conditions should be determined individually. The antibody detects an ~28 kDa band, corresponding to the expected molecular mass of FADD on immunoblots.
