Beclin 1 Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse Application:Western blot Western blotting (0.5-2 μg/ml). However, the optimal concentrations should be determined individually. Other applications have not been tested. The antibody recognizes ~53 kDa beclin 1 in Jurkat cell lysate. A weak band of ~110 kDa (possibly dimer) can also be observed in Jurkat cells. In mouse intestine tissue lysate, the antibody recognizes a ~100 kDa band (possibly dimer). Reactivity to other species has not been tested.
