Peptide 74（Cat No.:M117722）is a synthetic bioactive fragment derived from the laminin-1 α1 chain, known for its role in modulating cell behavior through interaction with cell surface receptors such as integrins. It promotes cell adhesion, migration, and signaling, particularly in epithelial and endothelial cells. Peptide 74 is frequently used in studies of tissue development, regeneration, and cancer progression, where extracellular matrix (ECM) interactions are critical. Its specific activity in mimicking laminin-mediated functions makes it a valuable tool in designing biomimetic materials and investigating mechanisms of cell-ECM communication in both health and disease contexts.
