Quantitation of 4E-BP1 (b) or eIF4G (c) with endogenous eIF4E in SW620 and HeLa cell lysates, determined by the electro-chemiluminescent binding assay fol- lowing incubation for 30 min with DMSO vehicle (Cont), 100 µM compound 4 or 100 µM RIIY peptide. Complexes were immobilised by an eIF4E antibody and captured eIF4E, eIF4G and 4E-BP1 detected by their respective secondary anti- bodies.
