P2 receptors (P2X 1 , P2X 4 , P2X 7 , P2Y 1 , and P2Y 11 ) compared by Western blotting in B cells and LCLs. Proteins extracted from B cells and LCLs were probed with rabbit polyclonal antibodies directed against P2X1 (60-kDa), P2X4 (65-kDa), P2X7 (68-kDa), P2Y1 (66-kDa), and P2Y11 (50-kDa) (left). Membranes were re-probed by GAPDH (40-kDa) (right). Data are representatives of 4 independent experiments.
