TCR alpha Antibody Host:Rabbit Antibody Type:Polyclonal Species Reactivity:Human, mouse, rat Application:Western blot, Immunoprecipitation, Immunohistochemistry Western blotting (0.5-4 μg/ml). Based on researcher’s feedback, it can also be used in immunoprecipitation (10-20 μg/ml); and Immunohistochemistry (15-25 μg/ml). However, the optimal concentrations should be determined individually. The antibody recognizes TCR α in human sample, and to a lesser extent to mouse and rat samples. Jurkat cell lysate can be used as a positive control.
