H-Cys-Asp-Pro-Gly-Tyr-Ile-Gly-Ser-Arg-OH trifluoroacetate (CDPGYIGSR) is a synthetic peptide sequence derived from the B1 chain of laminin, an extracellular matrix protein. It is used in cell biology research to investigate integrin-mediated cell adhesion, migration, and spreading, particularly via α1β1 and other integrins. Commonly applied in studies of angiogenesis, tumor cell metastasis, wound healing, and tissue regeneration. This peptide serves as a bioactive motif for coating surfaces in cell culture to promote selective attachment of epithelial, endothelial, and neuronal cells. Also employed in biomaterial development for scaffolds in tissue engineering and as a tool in assays for extracellular matrix interactions. Stable in neutral aqueous buffers at 4°C, ideal for in vitro experiments.
