LEESGGGLVQPGGSMK acetate（Cat No.:I044227）is a synthetic peptide with the amino acid sequence Leu-Glu-Glu-Ser-Gly-Gly-Gly-Leu-Val-Gln-Pro-Gly-Gly-Ser-Met-Lys, typically provided as an acetate salt for enhanced stability and solubility. It is used as a model substrate or standard in biochemical assays, including protease activity studies, structural analysis, and peptide interaction mapping. The sequence’s glycine-rich central region offers flexibility, while charged and hydrophobic residues contribute to diverse binding properties. Its defined composition makes it a valuable tool in analytical, enzymatic, and structural biology applications, particularly for method development and calibration in peptide research.
