Research Grade Snap-8 Peptide Acetyl Octapeptide-3 Lab-Grade Lyophilized Powder

   Product Detail   

Product Introduction

Snap‑8, also known as Acetyl Octapeptide‑3, is a synthetic acetyl‑modified octapeptide. It is a structural mimetic derived from the N‑terminal fragment of SNAP‑25 protein. This peptide is widely applied for pre‑clinical laboratory studies focusing on SNARE‑complex assembly, protein‑protein interaction and skin‑related biological pathways. Compared with acetyl hexapeptide‑8, it carries extra amino‑acid residues for enhanced molecular stability in experimental systems. Our product is supplied as high‑purity lyophilized off‑white powder, strictly for laboratory research applications only. Each batch is verified by HPLC and MS test, complete COA documents are available upon request.

Mechanism of Action

Snap‑8 functions as a competitive modulator targeting SNARE‑complex assembly process. It structurally imitates partial sequence of endogenous SNAP‑25 protein, and competes for binding sites within the SNARE molecular complex. Such competitive occupancy interferes with normal complex assembling progress, further mediates intracellular vesicle‑fusion related biochemical pathways in experimental cell models. It generates reversible molecular regulation instead of permanent protein cleavage. Researchers adopt this peptide as a laboratory tool to explore neuromuscular signal transmission and skin biological responses under non‑clinical conditions.
