Snap-8 Peptide

What is Snap-8?

Snap-8 is a synthetic peptide of 8 amino acids, known by its ingredient name acetyl octapeptide-3. Its sequence mimics the N terminal end of SNAP-25, a protein involved in releasing signals between nerve cells. It is used in cosmetic ingredient research. It is supplied as a lyophilized powder for in vitro laboratory research only.

How Snap-8 is tested

A good Snap-8 listing comes with a lab report for the exact lot in the vial. These are the results to look for:

• Purity (HPLC)

  How much of the sample is the compound

• Identity (MS or LCMS)

  Confirms it is the right molecule

• Net content

  The real mg in the vial versus the label

• Endotoxin (LAL)

  Bacterial residue, reported in EU

• Sterility

  Confirms nothing is growing in the vial

• Heavy metals (ICP-MS)

  Arsenic, cadmium, lead and mercury

Storage and handling

Lyophilized Snap-8 is stable at room temperature while it ships. For long term storage keep vials at minus 20 °C. Once reconstituted for laboratory use, store at 2 to 8 °C and use within 30 days.
