Micellar electrokinetic chromatography (MEKC) with laser-induced fluorescence (LIF) detection has been developed for a protein kinase assay. This protein kinase assay could readily determine the phosphorylation activity of substrate peptide kemptide using cAMP-dependent protein kinase (PKA) as a model enzyme.
