In vitro inhibitory enzyme kinetic assays are carried out in triplicate using the ATP/NADH coupled assay system in a 96-well format. The final reaction mixture contains 0.5mg/mL Bovine Serum Albumin (BSA), 2mM MnCl₂, 1mM phospho(enol) pyruvic acid, 1mM TCEP, 0.1M Hepes 7.4, 2.5mM poly-[Glu4Tyr1] peptide, 1/50 of the final reaction mixture volume of pyruvate kinase/lactic dehydrogenase enzymes from rabbit muscle, 0.5mM NADH, 0.5μM EGFR kinase, 100μM ATP and varied amount of inhibitors. Inhibitors and ATP are mixed and made separate stock from the mixture with all other ingredients and added last to the latter to start the reaction. Steady state initial velocity data are drawn from the slopes of the A340 curves^[1].
