BCR ligation promotes binding of Bim to Bcl-2. (A) Coimmunoprecipitation of Bim with Bcl-2. After lysis proteins were immunoprecipitated with Bcl-2 antibody, the immunoprecipitated proteins were fractionated by SDS-PAGE, blotted onto membranes, and probed with antibodies to BimL and BimEL (top) or Bcl-2 (bottom). (B) Western blot analysis of extracts from B cells that had been stimulated in culture with cross-linking F(ab′)2 anti-IgM antibodies or left untreated, using antibodies to Bim and Bcl-2.
