Binding profile of Bcl-B and members of the Bcl-2 family. FLAG-tagged Bcl-B was coexpressed with hemaglutinin (HA)-tagged Bcl-2 proteins as indicated. Cell lysates were divided into three equivalent fractions and co-immunoprecipitated with anti-FLAG, anti-HA or control (anti-Glu-Glu) antibodies and immunoblotted for anti-FLAG and anti-HA antibodies
