Generic peptide substrate for use in TR-FRET biochemical kinase assays. Refer to Selector Guide for validated kinases. ULight™-labeled synthetic peptide derived from residues 73-85 of rat Acetyl-CoA Carboxylase in which Ser77 is mutated to Ala (also known as SAMS). The ULight-Acetyl-CoA Carboxylase peptide can be phosphorylated at Ser 79 by the AMPKα1 kinase. Peptide sequence : CHMRSAMSGLHLVKRR. Please note this product replaces TRF0118-D or TRF0118-M, now being supplied lyophilized rather than in liquid (frozen) format.
