About Snap-8

Residues: 8
Molecular weight: 1075.2 g/mol
CAS number: 868844-74-0

SNAP-8 (acetyl octapeptide-3) is a synthetic octapeptide that is N-terminally acetylated and C-terminally amidated, an elongation of the acetyl-hexapeptide (Argireline) class. It has been described mechanistically as a peptide mimic of the N-terminal domain of SNAP-25 that can compete with SNAP-25 for incorporation into the SNARE complex, a tool approach for studying SNARE-mediated vesicle fusion.
