Product Description

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist with 94% structural homology to native human GLP-1. It features a key modification — an acylated fatty acid chain — that extends its biological half-life and enhances albumin binding. This peptide has become a cornerstone of metabolic research worldwide.

Laboratory Product Information

📦 Includes

One (1) vial of Semaglutide lyophilized powder (5mg per vial), Certificate of Analysis (COA).

🔬 Purpose

Semaglutide is a long-acting GLP-1 receptor agonist with 94% structural homology to native GLP-1, incorporating modifications for enhanced stability and extended receptor engagement. It is utilized in in-vitro GLP-1R binding assays, cAMP dose–response studies, and beta-cell glucose-stimulated insulin secretion models.

🧬 Ingredients
