Description
Snap-8 is an eight-amino-acid peptide, known in the literature as acetyl octapeptide-3 or acetyl glutamyl heptapeptide-3, supplied here as a research reagent for laboratory use. It is one of the more frequently requested research peptides in Canada among groups working on SNARE-complex biology, dermal and cellular ageing models, and topical formulation research. Each vial contains 10 mg of lyophilized material, intended for reconstitution in a suitable solvent by qualified personnel. It is not a drug, supplement or cosmetic and is not for human or veterinary use.
Overview
Snap-8 is structurally related to the N-terminal end of SNAP-25, a component of the SNARE protein complex, which is why it appears so often in in-vitro work on vesicle docking and fusion and in the cellular ageing literature. It arrives as a dry lyophilized powder in a sealed vial — the standard format for peptide reagents, because dry material is far more stable in transit and storage than anything pre-dissolved, and it lets the researcher set concentration to suit the protocol rather than working around a fixed one. Choose a single 10 mg vial for method development and pilot runs, or a box of ten where a study needs consistent material across repeats. Every batch is independently analysed by Janoshik, an external analytical laboratory, for purity by HPLC and identity by mass spectrometry, and the certificate of analysis supplied matches the batch in your hands rather than a generic reference document.
What it is known for
Buyers know Snap-8 as the octapeptide alternative to shorter SNAP-25-derived fragments in cosmetic and cellular research, and they choose this supply on the strength of the paperwork behind it. Third-party testing by an independent lab — not in-house numbers — plus a batch-matched COA is the difference between a reagent you can cite in a method section and one you have to qualify yourself. Domestic dispatch from Canada also removes customs delays and the temperature exposure that comes with them.
Key features
- Lyophilized powder format — Dry peptide is markedly more stable than solution, so material holds its integrity through shipping and storage until you are ready to reconstitute at your chosen concentration.
- Independent HPLC purity analysis (Janoshik) — Purity is verified by a lab with no stake in the sale, so impurity content is a measured value in your records rather than a manufacturer’s assurance.
- Mass spectrometry identity confirmation — Confirms the material in the vial is the peptide named on the label, which matters when octapeptides and closely related fragments are easy to confuse by name alone.
- Batch-matched certificate of analysis — The COA corresponds to the specific lot you receive, so results can be tied to documented material — a requirement for reproducible work and for most institutional QA processes.
- 10 mg vial, single or box of ten — Run a pilot without committing to bulk, or secure ten vials of consistent supply so a multi-arm or repeated study is not split across lots.
- Sealed single-use vial — Reduces the contamination and moisture-uptake risk that comes with repeatedly opening a shared container of hygroscopic peptide powder.
- Cold storage and tracked Canadian dispatch — Material is held cold before it leaves and moves domestically with tracking, keeping transit short and the chain of custody visible.
- Discreet packaging — Deliveries to shared labs, campus mailrooms or home offices arrive without disclosing contents.
Benefits
- Documented purity and identity you can file with your data rather than take on trust
- Reconstitute to whatever concentration your protocol calls for instead of adapting to a fixed one
- Consistent material across a study when ordered as a box of ten
- Short domestic transit, tracked end to end, with no international customs hold
- Clear, honest labelling as a research reagent — no wellness claims to unpick

Typical applications
- In-vitro investigation of SNARE complex assembly and vesicle fusion mechanisms
- Cellular ageing and dermal-model research programs
- Topical formulation and stability research at the bench
- Comparative studies against other peptides in the anti-ageing and cellular category
- Analytical method development, reference runs and instrument calibration work
Important information
- Research use only. Not a drug, supplement, food or cosmetic. Not for human or veterinary use, ingestion or administration.
- Keep the vial sealed and cold until use; allow it to reach room temperature before opening to limit condensation on hygroscopic powder.
- Reconstitute in a solvent appropriate to your protocol, adding it slowly against the vial wall rather than directly onto the powder, and avoid vigorous shaking.
- Once in solution, peptide stability is reduced — store reconstituted material cold, keep it protected from light, and plan aliquots to avoid repeated freeze-thaw cycles.
- Request or download the certificate of analysis for your lot and record the batch number alongside your results.
- Confirm the size you need before ordering: single vial for pilot work, box of ten where lot consistency across a study matters.
Common questions
What exactly is Snap-8?
An eight-amino-acid peptide, also written as acetyl octapeptide-3 or acetyl glutamyl heptapeptide-3, structurally related to a segment of the SNAP-25 protein. It is supplied here purely as a laboratory reagent.
Does it come with a certificate of analysis?
Yes. The COA is matched to the batch you receive and covers HPLC purity and mass spectrometry identity, both performed by Janoshik, an independent analytical laboratory.
How is it supplied?
As a lyophilized powder in a sealed vial containing 10 mg, available as a single vial or a box of ten. Nothing arrives pre-dissolved.
What solvent should I use?
That is determined by your protocol and downstream assay, so no solvent is supplied or specified. Reconstitution should be carried out by qualified personnel using a solvent suitable for the intended research application.
How should it be stored?
Keep the sealed vial cold until use. After reconstitution, store cold, protect from light, and aliquot where practical so the solution is not repeatedly frozen and thawed.
Can I buy this if I am not a laboratory?
The product is intended for qualified research buyers — laboratories, universities, biotech companies and researchers. It is not sold for personal use and is not for human or veterinary administration in any form.
Where does it ship from?
From within Canada, cold-stored before dispatch, packaged discreetly and tracked nationwide, so shipments stay domestic and avoid customs delays.
In summary
Snap-8 supplied the way a reagent should be: 10 mg of lyophilized peptide in a sealed vial, purity and identity verified by an outside lab, and a certificate of analysis tied to your specific batch. Order a single vial to validate it in your own hands, or a box of ten when a study needs one consistent lot from start to finish.
