Immune & Inflammatory Support
KPV is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (α-MSH), comprising the lysine-proline-valine residues responsible for much of α-MSH's reported anti-inflammatory signature. Published in vitro and rodent-model studies have characterised its uptake via the PepT1 transporter and its interaction with NF-κB and MAP kinase pathways in models of intestinal, dermal, and mucosal inflammation. For laboratory and research use only.

Compound Information
Tripeptide (α-MSH C-terminal fragment)
Storage & Stability
Lyophilized (powder)
-20°C • long-term stable in sealed lyophilized form
Reconstituted
2-8°C • use within 30 days of reconstitution
Light
Protect from light during storage and reconstitution
Room temperature
Short-term tolerant during shipping; minimise extended exposure above 25°C
Compound-specific notes
Aqueous KPV solutions show limited stability in published HPLC characterisation work; reconstituted material should be kept refrigerated, protected from light, and used within the validated window.
Dosing in the literature
Observational summary of values reported in published research. Not a guide for human or animal use.
Reconstitution
KPV (342.44 g/mol) is highly water-soluble. Published in vitro work typically prepares stock solutions in phosphate-buffered saline or distilled water at 1–10 mM; a 10 mg vial dissolved in 1 mL bacteriostatic water yields approximately 29 mM stock. In vivo rodent studies used aqueous oral or intracolonic delivery vehicles.
Published protocols
In vitro keratinocyte and epithelial-cell studies used KPV at 10 nM – 10 µM (Elliott et al., J Invest Dermatol 2004; Mandrika et al., Peptides 2003). Murine IBD models administered 50–500 µg/mouse orally or intracolonically (Dalmasso et al., Gastroenterology 2008; Kannengiesser et al., IBD 2008). Nanoparticle-mediated oral delivery in colitis models was examined by Xiao et al. (Biomaterials 2017). No human RCT data are available; all published protocols are preclinical.
Half-life
KPV is a tripeptide subject to rapid peptidase degradation in plasma and gastrointestinal environments. No pharmacokinetic half-life measurement is reported in the cited papers. PepT1-mediated uptake characterised by Dalmasso et al. (Gastroenterology 2008) suggests intestinal absorption occurs intact at micromolar concentrations, but systemic half-life remains uncharacterised.
Post-reconstitution stability
Aqueous KPV solutions have shown limited stability in published HPLC characterisation work; the storage note on this file advises keeping reconstituted material refrigerated and protected from light, used within the validated window. No specific stability endpoint is reported in the cited literature.
In vitro concentrations from Elliott et al. (J Invest Dermatol 2004, PMID 15102092) and Mandrika et al. (Peptides 2003, PMID 12750433). In vivo dose ranges from Dalmasso et al. (Gastroenterology 2008, PMID 18061177) and Kannengiesser et al. (IBD 2008, PMID 18092346). Half-life not reported in cited references; general tripeptide PK literature cited as basis for instability note.

Researcher FAQ
No. Aero Peptides materials are sold exclusively for in-vitro research and laboratory analytical use. They are not intended to diagnose, treat, cure, or prevent any disease, and are not approved for human or animal administration.
By placing an order, you confirm that you are a qualified researcher and that the material will be used in accordance with all applicable institutional and jurisdictional regulations.
Each lot is independently tested for identity, purity, and mass using HPLC and mass spectrometry. The COA lists the lot number, test date, assay results, and the laboratory that performed the analysis.
Public COA documents are being prepared. In the meantime, you can request a COA for your specific lot and we’ll email it within 1 business day.
Orders ship quickly after your order is placed, from the US. Lyophilized peptides are shipped with insulation appropriate to season; short-term ambient excursions during transit do not measurably affect potency.
On receipt, store at −20°C in the sealed vial until reconstitution. See the handling matrix for full storage parameters. Tracked shipping is included; we ship to all US states and most international destinations.
Most peptides are reconstituted with bacteriostatic water (BAC). The volume depends on the target working concentration. Use our Peptide Calculator to compute volume, U-100 insulin syringe units, and doses per vial from peptide mass and target dose.
Once reconstituted, store at 2–8°C and use within 30 days. Protect the vial from light during storage and handling.
Because peptides are temperature-sensitive research materials, we cannot accept returns of opened or unsealed vials. If a shipment arrives damaged or the seal is broken on arrival, contact us within 7 days and we’ll replace or refund.
See our full returns policy for details.
