DKK2 Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat Application:Western blot Western blotting (0.5-4 μg/ml). However, the optimal conditions should be determined individually. The antibody recognizes 30-35 kDa Dkk2 in samples from human, mouse and rat origins. A ~25 kDa band can also be detected, presumably to be the cleavage fragment of Dkk2.
