How to use

In Vitro:

Kemptide is a synthetic construct of a substrate for cAMP-dependent protein kinase (PK). Different types of intact cells catalyze the phosphorylation of Kemptide in the presence of extracellular ATP and cAMP with Km values of 3-4 uM for Kemptide. Kemptide is a synthetic peptide substrate derived from pyruvate kinase.
