A pool of Len/VD3-induced Bik protein was free from Bcl-2 and Bcl-xL. (a) IP assay of Bik in JEKO-1 cells. The Bik IP assay was performed in lysate of cells (107 cells) cultured for 4 days with or without 1 μM Len and 100 nM VD3. The expression of Bik, Bcl-2, Bcl-xL and Mcl-1 was analyzed in pellet (IP) and supernatant (OUT). (b) Reciprocal Bcl-2 and Bcl-xL IP assays. IP assays were performed by the simultaneous addition of both anti-Bcl-2 and anti-Bcl-xL antibodies to the lysates. The protein expression was analyzed in the total lysate (IN), pellet (IP) and supernatant (OUT) fractions
