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 studied for its actions on Y2 receptors and the resulting effects on food intake, so appetite and satiety studies often center on this peptide, and investigators measure feeding behavior and hormonal signals in animal models. Its defined sequence is reproducible in synthesis, and protocols commonly include dose-response designs. The powder reconstitutes cleanly, and our paperwork verifies purity and content. Trial and bulk supplies are available with secure packing. PYY 3-36 is released with purity documentation, and each vial is sealed to keep the peptide stable until reconstitution. Feeding studies often need a steady supply over several days, so we can provide bulk vials from one lot and coordinate delivery to match the dosing schedule without extra storage burden. Customer-focused service is our priority: transparent pricing, careful quality checks before release, safe packaging and dependable international shipping to the USA, Europe, Canada, Australia, the UK and beyond.
