Caspase-7 Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat Application:Western blot Western blot analysis (0.5-4 μg/ml). However, the optimal conditions should be determined individually. The antibody detects the full length (35-37 kDa) and the large fragment (20-25 kDa) of processed caspase-7 by Western blotting. Mouse small intestine tissue lysate can be used as a positive control.
