Liraglutide is a synthetic GLP-1 receptor agonist composed of the native GLP-1 sequence with a lysine-linked fatty-acid side chain that prolongs its activity through albumin binding. It is supplied as a high-purity white lyophilized powder, purity >=99% by HPLC, in sealed vials for laboratory research. Liraglutide is widely used in studies of glucose-dependent insulin release, appetite and satiety signaling, and body-weight regulation, and is commonly applied in cell-culture assays and preclinical metabolic models. The lyophilized format provides high stability and reproducible reconstitution, allowing consistent dosing in repeated experiments. Every batch is quality-controlled and batch-specific COA documents are available on request. Unopened product should be kept sealed at 2-8 degree C, protected from light and moisture, with -20 degree C recommended for long-term storage. We accept both small trial orders and bulk supply, and OEM and private-label packaging services are offered. This peptide is for laboratory research use only and is not intended for human or veterinary use.
