GLP-1 (Glucagon-Like Peptide-1, residues 7-37 amide) is a gut-derived incretin hormone that potently stimulates glucose-dependent insulin secretion and suppresses glucagon release, making it a fundamental tool in metabolic research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. GLP-1 is investigated in research on insulin secretion, glucose homeostasis, appetite regulation and pancreatic beta-cell function, and is widely applied in cell-based assays, receptor studies and preclinical metabolic experiments. The freeze-dried form ensures good stability and convenient reconstitution, supporting reproducible experimental dosing. Strict quality control is maintained on every batch, and COA is available for specific batches on request. For storage, keep sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage while avoiding repeated freeze-thaw cycles. Small and bulk orders are both welcome, with OEM and discreet neutral packing available. This bioactive form of glucagon-like peptide-1 represents the naturally processed circulating sequence, making it an authentic reference in incretin research. Studies often compare it with amidated variants and with synthetic analogs to map receptor pharmacology and degradation kinetics. The peptide is provided as a lyophilized powder with documented purity and recommended reconstitution guidance. The lyophilized format provides excellent stability and simplifies reconstitution for reproducible dosing.
