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. Native GLP-1 (7-37) serves as the reference ligand in incretin-receptor work, and the usual experiments measure receptor activation and insulinotropic responses while also tracking the peptide's degradation under physiological conditions. Because the native sequence is short-lived, designs often compare it against stabilized analogs to quantify the benefit of modification. Fresh stock is prepared for each readout, and the lyophilized format supports accurate reconstitution, with batch data included for methods sections. Each batch of native GLP-1 is released with its analysis record, and the lyophilized format supports the fresh preparation that short-lived peptides require. We can supply single-use trial vials or bulk aliquots for studies that need multiple preparations, and the packing is matched to the route so the powder stays stable. Storage notes are included with every shipment. We are a professional peptide supplier with in-house quality control, offering both small trial packs and bulk quantities at factory-direct prices. Every order is packed carefully and dispatched with tracking, and our team provides responsive after-sales support for research customers worldwide.
