VCP Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse Application:Western blot, Immunoprecipitation Western blotting (1:500 – 1:2000) and immunoprecipitation. However, the optimal concentrations should be determined individually. The antibody recognizes the 97 kDa VCP from samples of human and mouse origins. HeLa and NIH3T3 cell lysates can be used as positive controls. Reactivity to other species has not been tested.
