Overview
Researchers in SNARE-complex biology and neurotransmitter-release pharmacology can buy Snap-8 research peptide from Advanced Peptide Science at 99%+ HPLC-verified purity. Snap-8 (acetyl glutamyl heptapeptide-3, sequence Ac-EEMQRRA-NH2, MW 1075.2 Da) is a synthetic octapeptide analogue of SNAP-25.
Bacteriostatic Water (BAC Water) 30ml is required for reconstitution of this lyophilized compound. Available separately: Bacteriostatic Water 30ml.
Research Background
Snap-8 mimics the N-terminal region of SNAP-25 (synaptosomal-associated protein, 25 kDa), a component of the SNARE complex that mediates synaptic vesicle fusion. The peptide is investigated as a competitive disruptor of SNARE-complex assembly — a research approach distinct from neurotoxin-mediated SNARE disruption.
Mechanism of Action (Research Context)
Mechanism research investigates Snap-8 competition with native SNAP-25 for incorporation into the SNARE complex, reducing complex assembly efficiency and downstream vesicle fusion. Acetylcholine-release inhibition at the neuromuscular junction is the most-studied downstream endpoint in preclinical models.
Research Applications
- SNARE complex assembly pharmacology research
- Vesicle fusion pathway preclinical investigation
- Acetylcholine release inhibition mechanism studies at the neuromuscular junction
- Comparative neurotransmitter-release inhibitor research
- SNAP-25 analogue structure-activity relationship studies
