Assay Method Information

Assay Name:  Ki Determination
Description:  A coupled spectrophotometric assay was used in which ADP generated by kinase was converted to ATP with the concomitant production of pyruvate from PEP. LDH reduces pyruvate to lactate with the oxidation of NADH. NADH depletion was monitored at 340 nm using a microplate reader. The IC50 was evaluated from the data as a function of inhibitor concentration. The Ki value was calculated according to the Cheng-Prusoff approximation.
