In the specialized field of biochemical research, the exploration of synthetic sequences has opened doors to unders Laminin Pentapeptide YIGSR-NH2is a synthetic peptide consisting of the sequence: Tyr-Ile-Gly-Ser-Arg-NH2. The molecular weight of this peptide is 593.68 g/mol Read more tanding cellular behavior and extracellular matrix interactions. Among these, the CGYIGSR peptide—often discussed alongside its parent sequence, the laminin pentapeptide—represents a fascinating area of study for those interested in cell-adhesion motifs. As someone who follows the latest developments in peptide research, I have found the nuances of this specific sequence to be particularly compelling.
Understanding the Laminin Connection
The core of this research revolves around the laminin β1 chain. The YIGSR (Tyr–Ile–Gly–Ser–Arg) sequence is a well-documented functional motif that serves as the major receptor-binding site within the laminin protein. When researchers refer to YIGSR (Laminin Fragment 929-933), they are looking at the specific segment responsible for mediating the attachment, migration, and organization of various cell types.
The inclusion of the "C" (Cysteine) in CGYIGSR is often a strategic design choice, allowing for the covalent immobilization of the peptide onto surfaces or its conjugation to other molecules. This modification enhances the YIGSR-mediated attachment and spreading of a wide variety of cell types, making it a staple in 3D cell culture systems, such as VitroGel YIGSR High Concentration.
Key Research Observations
My interest in this peptide stems from its versatile biological profile. Based on the available scientific literature, several key functions have been observed:
* Collagen Synthesis: Studies have shown that this YIGSR peptide increases collagen type 1 synthesis in fibroblasts, which is a primary reason it is frequently investigated in dermal and epidermal research.
* Inflammatory Modulation: An emerging area of interest is how YIGSR can be used as a tool to modulate macrophage inflammatory state. Depending on the concentration, it acts as a YIGSR as a macrophage manipulating peptide, influencing how these cells respond within different phenotypes.
* Structural Mimicry: Scientists have developed conformationally constrained mimetics of the laminin cell-adhesion site, YIGSR, to better understand how these structures interact with integrin-associated receptors.
* Tissue Development: Because it is a functional motif of laminin that binds to the laminin receptor, it plays a critical role in how cells communicate with their environment during development.

When reviewing the data, it is important to note that YIGSR-NH2 seems to inhibit the invasiveness of melanoma cells in vitro and has an inhibitory effect on tumour growth and metastasis in specific models. Furthermore, its role in angiogenesis inhibition makes it a critical subject in vascular research.
Interestingly, I have seen reports where YIGSR treatment protected lymphedema impairment in epidermis and dermis, highlighting its potential in studies regarding lymphatic and tissue integrity. While many look for Cell-Adhesive Activity and Receptor-Binding Specificity of the a Laminin Pentapeptide YIGSR-NH2 for its purity—often reaching ≥98%—it is the specific biological interaction that remains the focus of the scientific community.
Considerations for Research Use
For those sourcing these materials, whether you are looking for a Laminin Pentapeptide or a specific YIGSR-NH2 variant, it is essential to prioritize high-purity sources. This ensures the consistency o Laminin Pentapeptide - 5 mg f results when observing how the YIGSR sequence may regulate tumor growth or facilitate cell adhesion.
