Description: Peptide to [Trp4]-Kemptide Form: 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.
