Description：Peptide to [Trp4]-KemptideForm：Lyophilized powder CAS Number：80224-16-4Molecular Formula：C40H66N14O9Molecular Weight：887.05Purity：> 95%Chemical Structure：Leu-Arg-Arg-Trp-Ser-Leu-GlyApplication：Chocktide ([Trp4]-Kemptide) is readily phosphorylated by cAMP-dependent protein kinase. The phosphorylated peptide, in turn, is an effective substrate for phosphoprotein phosphatase. The changes in the substrate fluorescence intensity as a function of its phosphorylation state provide a sensitive assay of both enzyme activities.Storage/Stability：Shipped at 4°C. Store at -20°C for one year.
