MCM2 Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse Application:Western blot, Immunoprecipitation Western blotting (1:500 – 1:2500) and Immunoprecipitation. HeLa cell extract can be used as a positive control. However, the optimal concentrations should be determined individually. The antibody recognizes the MCM2 of human origin. Reactivity to mouse is expected due to sequence homology. Reactivity to other species has not been tested.
