This antibody reacts with human DDB2 by western blot and immunoprecipitation. The antibody immunoprecipitates in vitro translated protein and protein from cell lysates (using 293T, and others). Coimmunoprecipitation of related proteins has not been tested. A 47.8 kDa band corresponding to human DDB2 is detected. Most cell lines expressing DDB2 can be used as a positive control. Researchers should determine optimal titers for other applications.
