This antibody reacts with human CDC20 (fizzy) by western blot and immunoprecipitation. The antibody immunoprecipitates in vitro translated protein and protein from overexpressing cell lysates (using HeLa and NIH-3T3, and others). Coimmunoprecipitation of related proteins has not been determined. A 54.7 kDa band corresponding to human CDC20 (fizzy) is detected. Most cell lines or tissues expressing CDC20 can be used as a positive control. Researchers should determine optimal titers for other applications.
