DNA-PK Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat, hamster Application:Western blot Western blot analysis (0.5-4 μg/ml). However, the optimal conditions should be determined individually. The immunoaffinity-purified antibody detects a >350,000 kDa and a 180,000 kDa protein (believed to be a processed form of the catalytic subunit), corresponding to the expected molecular weight of DNA-PKcs, in samples from human, mouse, rat and hamster origins.
