Product Overview

SNAP-8, also known as Acetyl Octapeptide-3, is a synthetic octapeptide derived from a region of the SNAP-25 protein involved in the SNARE complex.

It has been developed as a peptide research ingredient for investigating molecular mechanisms associated with neurotransmitter release, SNARE-complex activity, and facial muscle contraction. SNAP-8 is structurally related to Argireline (Acetyl Hexapeptide-8) but contains an extended peptide sequence.

SNAP-8 is particularly relevant to cosmetic peptide research involving the appearance of expression-related facial lines and mechanisms associated with localized muscle activity.

Mechanism of Action

Research has investigated SNAP-8 in relation to several molecular mechanisms, including:

SNARE Complex Research

SNAP-8 is derived from a region of SNAP-25 and has been studied for its potential interactions with components of the SNARE complex involved in vesicle fusion and neurotransmitter release.

Neurotransmitter Release Research

Experimental research has investigated SNAP-8 in relation to processes involved in neurotransmitter release at neuronal and neuromuscular junctions.

Muscle Contraction Research

Because the SNARE complex participates in neurotransmitter-mediated muscle activation, SNAP-8 has been investigated in experimental models related to localized muscle contraction.

Peptide-Protein Interaction Research

The peptide provides a research model for studying interactions between short synthetic peptides and proteins involved in vesicle fusion.

Cosmetic Peptide Research

SNAP-8 has been investigated as a cosmetic research ingredient in formulations designed to study the appearance of expression-related facial lines.
