Glucagon is a 29-amino-acid peptide hormone secreted by pancreatic alpha cells that raises blood glucose by promoting hepatic glycogenolysis and gluconeogenesis, making it a central tool in metabolic research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Glucagon is investigated in research on glucose counter-regulation, hepatic metabolism, energy balance and glucagon receptor signaling, and is commonly applied in cell-based assays and preclinical metabolic studies. The lyophilized form provides excellent stability and reproducible reconstitution for consistent experimental dosing. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only, not for human or veterinary purposes. The pancreatic hormone is essential for glycogenolysis, gluconeogenesis and lipid-metabolism research, and it is widely used as a standard in metabolic hormone assays. Investigators also study its counter-regulatory role in glucose homeostasis and its interaction with incretin peptides. Each vial contains a lyophilized powder with HPLC-confirmed purity and batch-level traceability. International orders are handled by our export department, which coordinates documentation, customs clearance and courier selection for each country. Parcels are sent with full tracking and delivery confirmation, and transit times are communicated before shipment. We also accept mixed orders of multiple peptides to simplify procurement for research teams. Questions about product use, pricing or delivery are always welcome, and our team responds quickly through multiple channels.
