Phospho-Glycogen Synthase Peptide-2 (substrate) TFA（Cat No.:I045810）is the trifluoroacetate salt form of a synthetic phosphopeptide substrate derived from glycogen synthase, an essential enzyme in glycogen metabolism. This peptide, containing a phosphorylated serine residue, is commonly used in kinase assays—particularly with glycogen synthase kinase-3 (GSK-3)—to study phosphorylation dynamics, enzyme activity, and signal transduction pathways. Its defined sequence and phosphorylation site make it a reliable biochemical tool for investigating glycogen regulation, insulin signaling, and metabolic control. The TFA salt enhances peptide stability and handling for experimental and enzymological research applications.
