Semaglutide is a long-acting glucagon-like peptide-1 receptor (GLP-1R) agonist. Medications based on semaglutide are currently widely used for the treatment of type 2 diabetes and obesity. Semaglutide physiologically mimics the function of endogenous GLP-1 hormone, promoting insulin secretion and suppressing glucagon secretion. It also slows gastric emptying, thereby helping patients control their food intake and body weight. This product is a recombinant E. coli-expressed semaglutide backbone. It is an intermediate peptide composed of 29 amino acids and serves as the starting peptide material for semaglutide synthesis. It is provided in lyophilized powder form. Features Animal-Origin Free: Produced using recombinant technology with no animal-derived materials, eliminating the risk of exogenous viral contamination. Stable Quality: Scalable batch production ensures high consistency and minimal lot-to-lot variation. High Production Capacity: Equipped with 5 L–1500 L fermentation systems, Yeasen Biotech supports diverse customer needs across research, pilot, and manufacturing scales.
