Description
SNAP-8 is a synthetic octapeptide research compound with the sequence Ac–Glu–Glu–Met–Gln–Arg–Arg–Ala–Asp–NH₂, structurally derived from SNAP-25, a core component of the SNARE protein complex involved in vesicle exocytosis. In laboratory research settings, SNAP-8 is studied for its ability to modulate vesicle fusion and neurotransmitter release mechanisms through competitive interaction with SNARE complex assembly.
Experimental studies utilize SNAP-8 as a molecular tool to investigate how interference with SNAP-25–dependent protein–protein interactions influences regulated exocytosis. By competing with endogenous SNAP-25 for SNARE complex formation, SNAP-8 provides a controlled model for examining catecholamine release regulation, vesicular trafficking, and cell–membrane interaction dynamics in non-clinical systems.
SNAP-8 is supplied exclusively for scientific and laboratory research use. It is not intended for human or veterinary consumption, clinical investigation, diagnostic use, or therapeutic application.

Storage & Handling
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
- On arrival: Store vials in a cool, dry place away from heat and direct sunlight.
- Long-term (powder): For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
- After reconstitution: Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Note: Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
