In the expansive field of biochemical research, the Laminin Pentapeptide YIGSR-NH2 stands out as a critical tool for those investigating extracellular matrix (ECM) interactions. As someone who follows the latest developments in synthetic chemistry and cellular biology, I have closely examined the utility of this specific sequence—Tyr-Ile-Gly-Ser-Arg-NH2—and its profound impact on experimental models.
Defining the Entity: YIGSR-NH2
The YIGSR-NH2 molecule is a synthetic pentapeptide derived from the laminin beta 1 chain (specifically residues 929-933). Often referred to as a Laminin Peptide YIGSR-NH2, this sequence is a cornerstone for researchers studying cell-matrix adhesion. The addition of the amide group (NH2) is a structural modification that influences the stability and biological activity of the peptide.
From a technical perspective, the molecule (CAS 110590-65-3) possesses a molecular weight of approximately 593.68 g/mol. Its high-purity profile, often exceeding 98%, ensures that observations in the lab are consistent and reliable.
Key Observations and Research Applications
