Application: 5-FAM CREBtide is a fluorescent synthetic peptide substrate derived from the phosphorylation site of cAMP response element-binding protein. It is selectively phosphorylated by protein kinase A, making it useful for quantifying PKA activity in fluorescence-based assay systems. The 5-FAM label enables direct and sensitive detection of phosphorylation-related assay outputs. 5-FAM CREBtide is widely used to study cAMP-dependent signaling pathways, transcriptional regulation, kinase activity, enzyme kinetics, and inhibitor screening. This peptide supports research into PKA-mediated cellular responses, phosphorylation-dependent signal transduction, and biochemical assay development for kinase pathway analysis.
