Tau Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat, chicken, bovine Application:Western blot Western blotting (0.5-4 μg/ml). However, the optimal conditions should be determined individually. Other applications have not been determined. The antibody recognizes mainly the truncated Tau (~30 kDa) in sample from human, mouse and rat origins. Other isoforms of Tau at 35 kDa, 60 kDa and 80 kDa can also be recognized. Reactivity to other species has not been tested.
