PYY 3-36 (Peptide YY, residues 3-36) is a 34-amino-acid gut hormone that acts as a satiety signal through Y2 receptor activation, widely studied in appetite and metabolic research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. PYY 3-36 is investigated in research on appetite suppression, energy intake regulation, gastrointestinal function and neuropeptide Y receptor signaling, and is commonly applied in cell-based assays and preclinical studies. As a research peptide with a defined sequence, it does not have a single unified CAS number. The freeze-dried form ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is maintained on every batch, and COA is available on request. Keep sealed at 2-8 degree C away from light; -20 degree C recommended for long-term storage. PYY 3-36 is the Y2-receptor ligand around which appetite studies are built, and the design usually measures feeding behavior and hormonal signals in animal models while testing dose-response relationships. The defined sequence keeps synthesis reproducible, and the lyophilized format supports the repeated preparation that feeding protocols require. Our records verify purity per lot, and we can supply matched vials for multi-arm designs with packing matched to the route. Each batch of PYY 3-36 ships with its purity record, and the peptide is packed to remain stable until reconstitution. Feeding studies that run over several days can order bulk vials from one lot, and we can align delivery with the dosing schedule. Storage notes cover both powder and prepared solution, and matched sets are available for multi-arm designs. With a stable supply chain and strict quality control, we serve research teams and distributors in many countries. Every parcel is professionally packed and tracked, and we provide timely communication from order to delivery, plus after-sales support.
