SNAP-8 (Acetyl Octapeptide-3): Research Reference

SNAP-8 is a short synthetic peptide first described in cosmetic-science research as an extension of acetyl hexapeptide-3. Both ends of the molecule are capped: an acetyl group on the N-terminus and an amide on the C-terminus. Capping removes the free charged ends, which generally makes a short peptide more resistant to exopeptidases. It belongs to the group of acetylated short peptides studied in that field.

NuRev lots are tested by independent third-party laboratories. A useful Certificate of Analysis for a research peptide shows:

• Identity by mass spectrometry, matched to the expected molecular weight (about 1075 Da)
• Purity by HPLC, with the chromatogram
• A lot number identical to the one printed on the vial
• The name of the testing laboratory and the test date

Each NuRev vial label carries a QR code that opens the matching lot’s documents. All published reports are in the certificate of analysis library; see how to read a peptide COA for what each section means.

SNAP-8 contains a methionine residue, which can oxidize. General practice for lyophilized peptides applies:

• Store the sealed vial at −20 °C, protected from light and moisture. Short-term storage at 2–8 °C is acceptable.
• Let the vial reach room temperature before opening, to avoid condensation.
• After reconstitution, aliquot the solution and avoid repeated freezing and thawing.

More detail is in our peptide storage guide. NuRev supplies SNAP-8 10 mg for laboratory research use only.
