Potential Applications in Research

Strictly in-vitro, cell-free, or cell-based experiments. No health claims or clinical/veterinary use.

SNARE-mediated liposome fusion assays (lipid/content mixing) to probe effects on reconstituted v/t-SNARE assembly and fusion kinetics in defined proteoliposome systems.
FRET-based SNARE complex assembly measurements (e.g., labeled SNAP-25/VAMP/Syntaxin constructs) to quantify assembly/disassembly dynamics in real time.
Exocytosis model workflows in neuronal or neuroendocrine cell lines (e.g., dye-based vesicle release readouts) under controlled depolarization and Ca²⁺ conditions.
Analytical method development (RP-HPLC and LC–MS/MS) for identity, stability, and matrix-recovery of acetylated peptides in buffered systems.
Peptide–material interaction screens (e.g., inorganic cluster/polyoxometalate systems) to characterize non-covalent assembly and adhesion-related properties in vitro.

Quality, Storage & Handling

Every lot is confirmed by HPLC (purity) and MS (identity); batch-level COA is accessible via on-vial QR. Independent U.S. labs verify purity, quantity, and endotoxin.

Storage (lyophilized): −20 °C long-term or 2–8 °C short-term; keep desiccated and protected from light.
After reconstitution: Aliquot and store at ≤−20 °C; avoid repeated freeze–thaw cycles.
Reconstitution tips: Use sterile water or suitable buffer; gentle inversion to dissolve; 0.22 µm filter only if required by your SOP.

Shipping & Fulfillment

Ships with validated cold-chain packaging. In-stock orders placed before the daily cutoff ship the same day. 2-Day FedEx/UPS is standard, with overnight options available. Automated text/email updates included; international shipping available where permitted.

Compliance & RUO Disclaimer

For laboratory research only. Not a drug, cosmetic, food, or household chemical. Not for human or animal use, diagnostic, or therapeutic applications. Buyers warrant they are qualified to handle RUO materials under applicable laws and institutional guidelines.

FAQs

Is this intended for human or veterinary use?: No. This product is sold strictly as RUO and must not be used in humans or animals.
What purity do you provide?: Each 10 mg vial is ≥99% by HPLC with MS identity confirmation; third-party testing is performed on every lot (see COA via QR).
How should I reconstitute it?: Use sterile water or compatible buffer; gently invert until fully dissolved. If your protocol requires sterility, pass through a 0.22 µm filter and aliquot to avoid repeat freeze–thaw.
Which in-vitro assays is SNAP-8 commonly used in?: Typical RUO uses include reconstituted liposome fusion assays, FRET-based SNARE assembly measurements, dye-tracked exocytosis models, and LC–MS/MS method development.
