GLP-1 (7-36) amide is the principal circulating form of glucagon-like peptide-1, a 30-amino-acid incretin hormone released after meals to amplify glucose-stimulated insulin secretion and suppress glucagon output. As the physiologically active sequence, it serves as a reference standard in receptor-binding assays, insulin-secretion studies and beta-cell biology research. It is supplied as a white lyophilized powder at >=99% HPLC purity in a sealed vial. Cold-chain logistics and batch documentation support reproducible results across independent laboratories. Samples for quality evaluation can be arranged for serious buyers, with sample cost credited against the first bulk order in most cases. Our pricing structure supports both small laboratory orders and large wholesale contracts, and payment options include major transfer and trade platforms.
