Oxyntomodulin is a 37-amino-acid proglucagon-derived peptide that co-activates both GLP-1 and glucagon receptors, making it a unique dual-signaling tool in metabolic research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Oxyntomodulin is investigated in research on appetite suppression, energy expenditure, glucose metabolism and dual-receptor signaling, and is commonly applied in cell-based assays and preclinical metabolic studies. As a research peptide with a defined sequence, it does not have a single unified CAS number. The freeze-dried format ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is applied to every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage. Small and bulk orders are both welcome with OEM and discreet neutral packing offered. For laboratory research use only.
