A. Bcl-2 was immunoprecipitated from ALL-19 cells and subjected to
immunoblotting for Bcl-2 and the indicated pro-apoptotic Bcl-2 family members.
WCE, whole cell extract; Sup, supernatant; IP, immunoprecipitate; eluant,
detergent eluant of immunoprecipitate. Samples were obtained from
immunoprecipitations performed in the absence (−) or presence (+) of
Bcl-2 antibody. Asterisks indicate non-specific bands. B, C, and D.
Bax (panel B), Bim (panel C) or Bik (panel
D) were immunoprecipitated from ALL-19 cells, and subjected to
immunoblotting for the proteins indicated.
