This antibody reacts with human SKP1 by western blot and immunoprecipitation. The antibody immunoprecipitates in vitro translated protein and protein from cell lysates (using HeLa, NIH-3T3, and others). Coimmunoprecipitation of cyclin A and Cuol1 may occur. An 18.5 kDa band corresponding to human SKP1 is detected. Most cell lines expressing SKP1 can be used as a positive control. Researchers should determine optimal titers for other applications.
