MAPKAPK-2 Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat, dog, bovine Application:Western blot, Immunoprecipitation Western blot analysis (0.5-4 μg/ml) and immunoprecipitation. However, the optimal conditions should be determined individually. The affinity purified antibody detects both 43 and 60 kDa isoforms, corresponding to the apparent molecular mass of MAPKAPK-2 on SDS-PAGE immunoblots. These 43 kDa and 60 kDa bands can be specifically inhibited by the relevant peptide.
