ROCK1 Antibody (Clone 12M03) Host:Mouse Antibody Type:Monoclonal Species Reactivity:Human Application:Western blot Western blotting (1-4 μg/ml). However, the optimal conditions should be determined individually. Jurkat cell lysate treated with camptothecin (2 μM for 6-8 hours) can be used as a positive control. The antibody has been selected for its ability to recognize the cleaved ROCK-1 in Western blotting. It does not recognize the full length protein.
