SNAP-8, also known as Acetyl Octapeptide-3, is a synthetic octapeptide studied in research involving the SNAP-25 protein, SNARE complex biology, vesicle fusion, and peptide-based cosmetic science. As an extended peptide related to Argireline, SNAP-8 is of interest to researchers investigating peptide structure, protein-peptide interactions, neurotransmitter-release pathways, and topical cosmetic formulations. Published analytical research has also established LC-MS/MS methods for identifying and quantifying Acetyl Octapeptide-3. Helix Bio supplies SNAP-8 as a research-use-only material for qualified laboratory and scientific applications. The company states that its research peptides are supported by batch-specific COA documentation and third-party HPLC and mass-spectrometry testing.

SNAP-8 is the common research and cosmetic name for Acetyl Octapeptide-3, a synthetic eight-amino-acid peptide associated with research into the SNAP-25 portion of the SNARE complex.
The SNARE complex is a group of proteins involved in membrane fusion and vesicle-release processes. SNAP-25 is one of the proteins participating in this molecular machinery. Research on SNAP-8 examines how a short synthetic peptide corresponding to part of the SNAP-25 sequence can interact with this system.
SNAP-8 is often discussed alongside Argireline because both peptides are related to the SNAP-25 region and have been studied in cosmetic peptide research. SNAP-8 is an extended analog containing eight amino-acid residues rather than the shorter six-residue sequence associated with Argireline.
For laboratory researchers, this makes SNAP-8 relevant to studies involving peptide-protein interactions, SNARE-related signaling, vesicle fusion models, and cosmetic formulation science.
SNAP-8 is classified as a synthetic octapeptide. Its commonly reported sequence is:
Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH₂
The peptide contains eight amino-acid residues and an N-terminal acetyl modification. Its structure is related to a region of SNAP-25 that participates in SNARE-complex assembly.
Important research characteristics include:
SNAP-8 and Argireline are closely related but are not identical peptides.
Argireline is associated with Acetyl Hexapeptide-3/Acetyl Hexapeptide-8 nomenclature, while SNAP-8 is Acetyl Octapeptide-3. SNAP-8 extends the related sequence with two additional residues.
| Characteristic | SNAP-8 | Argireline |
|---|---|---|
| Common Name | SNAP-8 | Argireline |
| Peptide Type | Synthetic octapeptide | Synthetic hexapeptide |
| Common Scientific Name | Acetyl Octapeptide-3 | Acetyl Hexapeptide-3 / Acetyl Hexapeptide-8 |
| Sequence Length | 8 residues | 6 residues |
| Research Relationship | Extended SNAP-25-related peptide | Shorter SNAP-25-related peptide |
| Research Focus | SNARE/SNAP-25 interactions and cosmetic peptide science | SNARE/SNAP-25-related research and cosmetic formulations |
The two compounds should not be treated as interchangeable. Researchers should identify the exact peptide, sequence, formulation, purity, and lot documentation required for a given experiment.
Helix Bio's SNAP-8 is intended exclusively for laboratory and scientific research.
Potential research areas include:
The appropriate application depends on the research model, experimental objective, analytical methodology, and laboratory protocol.
Defined Peptide Identity
Research involving synthetic peptides benefits from clearly defined molecular identity. SNAP-8 has a recognized sequence and chemical identity, allowing researchers to distinguish it from related peptides such as Argireline.
Relevant to SNARE Biology
SNAP-8 is associated with the SNAP-25 portion of the SNARE complex, giving researchers a defined peptide model for investigating protein interactions and membrane-fusion biology.
Established Analytical Methods
Published research has described LC-MS/MS methodology for the identification and quantification of Acetyl Octapeptide-3, demonstrating that the compound can be analytically characterized using modern mass-spectrometric methods.
Useful for Cosmetic Peptide Research
SNAP-8 has been studied in cosmetic science, including research concerning topical formulations and peptide-based approaches to expression-line models. The available evidence should be interpreted according to the specific formulation, experimental model, and study design rather than generalized to every SNAP-8 preparation.
Documented Quality Approach
Helix Bio states that its peptide catalog uses third-party HPLC and mass-spectrometry testing, with batch-specific certificates of analysis. Researchers can use this documentation to evaluate the identity and purity of the material associated with a specific lot.
SNAP-8 is intended for qualified scientific and laboratory users, including:
It is not intended for consumers seeking cosmetic treatment, anti-aging treatment, medical treatment, or self-administration.
