SNAP-8 — compound background
Acetylated octapeptide (Acetyl Octapeptide-3), SNAP-25 N-terminal mimetic
SNAP-8 (Acetyl Octapeptide-3) is an eight-residue, N-acetylated topical cosmetic research peptide — an elongation of the well-known hexapeptide Argireline. It mimics the N-terminal end of SNAP-25 and is studied for competing within the SNARE complex that governs signalling at the neuromuscular junction.
Solubility & reconstitution
Water-soluble and dissolves readily. The N-terminal acetyl cap adds stability. Typically studied in aqueous topical preparations.
Freely soluble at cosmetic working concentrations.
Storage
Sealed powder stable at -20 °C. Refrigerate at 2-8 °C.
Commonly worked with for several weeks at 2-8 °C — the acetyl cap and lack of oxidation-prone residues help.
Stability
The N-acetylation blocks aminopeptidase attack at the N-terminus, one reason acetyl peptides are favoured in cosmetic formulation research.
Reading the Certificate of Analysis
Confirm the mass near 1075.3 Da and that the N-acetyl group is present (an unacetylated impurity would sit 42 Da lighter).
