Snap8 Spray delivers Snap8, a synthetic eight-residue peptide, sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2, modeled on a short stretch of SNAP-25, a protein that forms part of the SNARE membrane-fusion complex. Its formula is C41H70N16O16S, molecular weight 1075.2 g/mol, CAS 868844-74-0, PubChem CID 76283482. The acetylated N-terminus and amidated C-terminus distinguish it from a plain SNAP-25 fragment of the same length. Available in 10 mg and 20 mg spray-dispensed sizes for laboratory research use only.

Snap8 Spray is Veracue’s spray-dispensed packaging of Snap8, a synthetic octapeptide built from eight amino acids and modeled on a short stretch of SNAP-25, a protein that forms part of the SNARE membrane-fusion complex. The underlying molecule is identical to the one documented on Veracue’s Snap8 vial listing; only the packaging and dispensing format differ between the two listings.
"Spray" is a packaging and dispensing descriptor, nothing more. It does not establish a route, a concentration, or a formulation, and none of those specifics should be inferred from the product name. Chemical form, concentration, fill volume and storage conditions are reported on each lot’s own documentation and can be requested through the contact page.

Veracue lists Snap8 in more than one packaging format because research groups source and track material differently depending on how it is packaged. Keeping the formats as separate listings keeps lot records, images and documentation specific to the packaging a researcher actually ordered, rather than mixing records across formats.
Snap8 Spray and Veracue’s Snap8 vial listing describe one molecule: a linear eight-residue chain, Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2, carrying an acetyl group at the N-terminus and an amide at the C-terminus in place of a free carboxylic acid. Packaging format has no bearing on sequence, formula or mass, so these values are identical across both listings.
No. The compound reported under this listing is the same Ac-EEMQRRAD-NH2 octapeptide reported under the vial listing. What differs between the two listings is how the material is packaged and dispensed, not its chemical identity.
In Veracue’s catalog, "Spray" is a packaging and dispensing term, comparable to "vial" or "powder" on other listings. It tells a researcher how the product is dispensed from its container. It does not specify a concentration, a carrier, a route, or a formulation, and it is not shorthand for any particular method of use. Those details, where applicable, live in lot-specific documentation rather than in the catalog name.
Treating a packaging word as a technical specification is a common source of error when comparing listings across suppliers. A researcher documenting materials in a methods section should cite the lot’s own documentation for format-specific details rather than inferring them from the word "Spray" alone.
| Feature | Snap8 | Argireline | GHK-Cu |
|---|---|---|---|
| Structure | Synthetic linear octapeptide, Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2 | Synthetic linear hexapeptide, Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2 | Copper(II) complex of the tripeptide Gly-His-Lys |
| Length | 8 residues | 6 residues | 3 amino acids plus a coordinated copper ion |
| Molecular formula | C41H70N16O16S | Shorter related sequence core, distinct formula | Distinct formula from either peptide |
| Design association | Modeled on a short sequence from SNAP-25 | Shares the same sequence core as Snap8, modeled on SNAP-25 | Unrelated design lineage; copper-peptide chemistry |
| Catalog formats Veracue offers | Vial and spray | Not currently listed | Vial and spray |
This table compares molecular structure and design lineage only. Catalog format is listed separately because it is a packaging detail, not a property of the molecule itself, and it does not change which sequence a given peptide carries.
SNAP-25 is a well-characterized protein that, together with syntaxin-1 and VAMP/synaptobrevin, forms the core SNARE complex involved in vesicle docking and membrane fusion. Snap8 corresponds to a short stretch of the SNAP-25 sequence, near its N-terminal region, and is studied at the molecular level as a reference material for SNARE-related assay work in either packaging format Veracue offers.
Because "Spray" and "vial" describe packaging rather than chemistry, a methods section should still name the molecule precisely by sequence or CAS number, and separately note the catalog format and lot number actually used. This page provides molecular reference information and general research context only, and Veracue provides no dosing, administration or usage guidance of any kind.
Identity and purity for Snap8 Spray are established the same way as for any Snap8 lot: reverse-phase HPLC for chromatographic purity, and mass spectrometry (typically ESI-MS or MALDI-TOF) to confirm that the observed mass matches the molecule’s theoretical value of 1075.2 g/mol. HPLC alone shows that most detected material elutes together; it does not by itself confirm identity, since a closely related peptide such as Argireline can produce an equally clean trace.
Packaging format has no bearing on which analytical methods apply. A spray-dispensed lot and a vial lot of the same molecule are verified against the same sequence, formula and mass references, listed on the Snap8 at a Glance table above.
| Method | Tells a researcher | Does not prove by itself |
|---|---|---|
| RP-HPLC | Chromatographic purity (area %) | Identity |
| ESI-MS / MALDI-TOF | Mass consistent with Snap8 | Sequence order; purity |
| Tandem MS | Sequence evidence | Quantity or purity |
| Amino acid or elemental analysis | Net peptide content | Identity of impurities |
A certificate of analysis describes one lot, never a packaging format or a compound in general. Before relying on any figure, confirm that the lot number on the certificate matches the container and the order record for the spray-format unit received.
A complete certificate separates product identity, lot number, chemical form, HPLC result with chromatogram, mass spectrometry result with observed and theoretical mass, test date and testing laboratory. Where concentration or fill-volume figures are relevant to a spray-format unit, they are reported on that lot’s own documentation rather than inferred from the catalog listing. The certificate page explains how to request lot documentation for either format.
No. The verification question is the same: does this lot match the stated molecule, and is the purity figure paired with a mass result from the same lot. Packaging format does not change what counts as adequate documentation.
Some third-party listings describe Snap8 as an acetate salt rather than the free peptide, and the two forms carry slightly different expected masses. If a lot’s documentation leaves the form unstated, any mass-based calculation can carry a silent error. Confirm the form on the lot’s certificate and use the matching formula weight, regardless of packaging format.
For each lot, keep the catalog listing snapshot, the lot-specific certificate, the stated chemical form, the receipt date, labeled storage conditions, and the packaging format actually received. Recording format alongside the usual identity fields keeps multi-format catalogs like this one traceable lot to lot.
Snap8 Spray is supplied for laboratory research and analytical characterization only. It is not intended for human or veterinary use, or for ingestion, injection or any form of administration. This page contains no dosing, administration or usage guidance of any kind, and the word "Spray" in the product name describes Veracue’s packaging and dispensing format only.
