This antibody reacts with human ROC2 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 does occur. A 12.6 kDa band corresponding to human ROC2 is detected. Most cell lines expressing ROC2 can be used as a positive control. Researchers should determine optimal titers for other applications.
