Snap-8
SNAP-25 mimetic octapeptide for topical cosmetic research.
Class
SNAP-25 mimetic octapeptide
Half-life
Topical — N/A systemic
Studied in
Topical expression-line cosmetic research models.
What it is
Snap-8 (acetyl octapeptide-3) is an extended analogue of Argireline that competes with SNAP-25 in the SNARE complex. Investigated as a topical cosmetic-research peptide for expression-line endpoints.
Mechanism studied
Competes with SNAP-25 in the SNARE complex to modulate vesicle docking.
Research notes
- Used in dermal in-vitro assays of vesicular release machinery.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
