Frequently Asked Questions (RUO Compliance)

1. What is the chemical composition and sequence of SNAP-8?

SNAP-8, also called Acetyl Octapeptide-3, is a synthetic octapeptide with the sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2. Its molecular formula is C41H70N16O16S, with a molar mass of approximately 1075.15 g/mol (CAS 868844-74-0).

2. What research areas is SNAP-8 studied in?

In vitro and preclinical studies examine SNAP-8 in relation to SNAP-25-associated neurotransmission pathways, SNARE-complex formation and neuromuscular signaling in experimental models.

3. How is the purity of each SNAP-8 batch verified?

Each lot is analyzed by High-Performance Liquid Chromatography (HPLC) for chromatographic purity and by Mass Spectrometry (MS) to confirm molecular identity. Endotoxin (LAL) and sterility testing are also performed, and results are recorded on the batch Certificate of Analysis.

4. How should lyophilized SNAP-8 be stored upon arrival?

Store unopened lyophilized vials at -20°C to 4°C in a dry, dark location. Under these conditions the powder remains stable for 24 months or longer.

5. What diluent is used to reconstitute SNAP-8 for laboratory work?

Laboratories commonly reconstitute SNAP-8 with sterile bacteriostatic water (0.9% benzyl alcohol) or sterile 0.9% sodium chloride, selected according to the assay protocol and how many times the vial will be sampled.

6. What is the proper technique for adding diluent to the SNAP-8 vial?

Working under aseptic conditions, add the diluent slowly down the inside wall of the vial rather than directly onto the powder. Swirl gently until fully dissolved; do not shake or vortex.

7. How should reconstituted SNAP-8 be stored?

Keep reconstituted solution refrigerated at 2–8°C and protected from light, and use it within 30 days. Avoid repeated freeze-thaw cycles, direct sunlight and temperatures above 25°C, which can degrade the peptide.

8. Where can researchers find the Certificate of Analysis for SNAP-8?

The current batch COA, including HPLC and mass spectrometry results, can be downloaded from the Lab Reports tab on this page and from the Research Labs Lab Reports library.

9. What size and synonyms apply to SNAP-8?

SNAP-8 is supplied as a 10 mg lyophilized vial (Ref. SNA-0010VI). In the literature it may also appear as Acetyl Octapeptide-3.

10. What is the regulatory status of SNAP-8 sold by Research Labs?

This compound is supplied strictly for in vitro laboratory research by qualified personnel. It is not approved, intended or labeled for human, clinical, cosmetic or veterinary use.
