KPVResearch-Grade Peptide · Lab-Verified Purity
KPV is a tiny three-amino-acid piece of the α-MSH hormone — the end fragment that scientists discovered retains most of α-MSH's inflammation-calming effects. It's one of the smallest research peptides on the market, which makes it exceptionally water-soluble and easy to work with.
Everything researchers need to know about KPV
Manufacturing, testing, handling, and shipping details for KPV. For research purposes only — not for human or animal consumption.
KPV — Product Overview
KPV is a tiny three-amino-acid piece of the α-MSH hormone — the end fragment that scientists discovered retains most of α-MSH's inflammation-calming effects. It's one of the smallest research peptides on the market, which makes it exceptionally water-soluble and easy to work with.
KPV — Molecular Characteristics & Vial Specifications
ProSource Labs supplies KPV in the following available vial sizes: 10mg. Each KPV vial contains pure lyophilized peptide — no fillers, no bulking agents. Product SKU references: KPV-10MV.
- Anti-Inflammatory: Best-known for calming inflammation in gut and skin study models
- Gut Lining Focus: Rodent colitis and IBD-model literature is where KPV shines
- Tiny Peptide: Just 3 amino acids — the shortest peptide typically stocked
- Highly Soluble: Dissolves easily thanks to its small, water-loving structure
Batches are characterized by ESI mass spectrometry to confirm molecular weight against the theoretical value, with amino-acid sequence confirmation on selected QA lots. Peptide content assay distinguishes net peptide mass from residual counter-ion salt.
KPV — Laboratory Handling & Storage
Lyophilized KPV vials should be stored at -20°C (or colder) in a laboratory freezer, inside the sealed factory container. Minimize warm-up cycles — move only the specific vial needed for a given experiment out of frozen storage at a time.
All laboratory handling of KPV should follow the receiving institution's SOPs and applicable peer-reviewed protocols relevant to the researcher's specific experimental question. ProSource Labs does not publish end-user preparation or usage instructions.
KPV — Third-Party Analytical Testing
Every batch of KPV released by ProSource Labs undergoes independent reverse-phase High Performance Liquid Chromatography (HPLC) — the industry-standard analytical method for this class of research compound. Target chromatographic purity is typically ≥ 99%.
Additional characterization may include ESI mass spectrometry for molecular weight confirmation, Karl Fischer titration for residual moisture, and appearance/solubility inspection. A batch-specific Certificate of Analysis (COA) is available on request through customer support after purchase.
KPV — Quality Assurance Process
Each production lot of KPV is quarantined pending analytical release, tested against documented purity, identity, and moisture acceptance criteria, and only released to sellable inventory after passing every QA checkpoint. Batches that fail any single criterion are quarantined and never reach customer-facing inventory.
If a vial of KPV you received from ProSource Labs ever fails your own institution's incoming QA testing, contact customer support at support@prosourcelabs.org — we retain samples of every batch for cross-verification.
KPV — Typical Research Application
Research research on inflammation, gut lining repair (rodent colitis models), and dermal wound healing. Its very small size gives it unusual properties for a peptide — including reported oral bioavailability in rodents.
KPV — Packaging & Fast Southern California Shipping
KPV vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.
Every KPV shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
