What is — KPV
KPV is a synthetic tripeptide (lysine-proline-valine) corresponding to the C-terminal fragment of the alpha-melanocyte-stimulating hormone (α-MSH). Peptworks supplies it as a lyophilised 10 mg vial at >=98% HPLC purity. It is a research-use-only (RUO) laboratory reagent — not a medicine, supplement, cosmetic or medical device, and not for human or animal consumption. Stock ships from inside the EU for intra-community delivery in 3-5 business days, available as bulk unbranded vials or as white-label boxes under the reseller's own brand.
As the C-terminal tripeptide of α-MSH, KPV is studied within the melanocortin signalling area. In preclinical and in-vitro models, research has focused on its interaction with intracellular inflammatory signalling pathways, including reported modulation of NF-κB-associated transcriptional activity and pro-inflammatory cytokine expression in cultured cells. Peptworks describes these mechanisms strictly as research-model observations; no therapeutic mechanism in humans is claimed or implied.
Research
- Melanocortin pathway and α-MSH fragment signalling (in vitro)
- NF-κB and intracellular inflammatory pathway modulation in cell cultures
- Epithelial and intestinal barrier research models
- Wound-healing and tissue-repair assays (preclinical)
- Pro-inflammatory cytokine expression studies
- Peptide stability, reconstitution and formulation R&D
Advantages
- In cell-culture models, studied for modulation of pro-inflammatory signalling
- Investigated in preclinical tissue-repair and epithelial-barrier models
- Used as a reference α-MSH C-terminal fragment in melanocortin pathway screening
- >=98% HPLC purity supports reproducible in-vitro experimental data
- Lyophilised 10 mg format allows flexible reconstitution for varied laboratory protocols
Safety
- As an RUO reagent, no human or clinical safety profile has been established
- Preclinical literature generally reports KPV as low-toxicity in the models studied, though available data are limited
- Handle as a laboratory chemical: use appropriate PPE and follow local lab safety and disposal protocols
- Reconstituted peptide stability is limited; store and handle according to laboratory best practice
Ideal for
- In-vitro inflammation and cytokine-expression assays
- Melanocortin / α-MSH pathway research programmes
- Epithelial and gut-barrier model studies
- Comparative peptide screening and reference standards
- Formulation, reconstitution and stability R&D
- White-label catalogue expansion for B2B research suppliers
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.
Frequently asked questions
Where can I buy KPV in bulk in the EU?
Peptworks supplies KPV (10 mg lyophilised vial) wholesale to B2B buyers from stock already inside the EU. Orders ship intra-community in 3-5 business days with no customs clearance. You can order bulk unbranded vials or white-label boxes under your own brand. The minimum order is 10 units (one box of 10) per reference.
What is the wholesale KPV price per vial?
Per-vial pricing is public and uses a single combined-volume discount applied to the whole order: EUR 19.00/vial at 100 units, EUR 15.58 at 300 units (-18%), EUR 14.25 at 500 units (-25%), and EUR 12.92 at 1000 units (-32%). The tier is set by your combined total units across references, not stacked. Payment is by USDC bank transfer / invoice.
Do you offer white-label KPV?
Yes. Peptworks offers white-label KPV: vials labelled with your own brand and boxed. A one-time label setup fee of EUR 180 applies for orders under 100 units and is free from 100 units onward. If you prefer to label in-house, you can also order bulk unbranded vials.
What is the minimum order for KPV?
The minimum order is 10 units — one box of 10 vials — per reference. Vials always ship in boxes of 10, and each box carries the Peptworks label plus a unique QR code linking to that batch's Certificate of Analysis.
How is the KPV Certificate of Analysis verified?
Every batch ships with an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy-metals testing. Each box carries a unique QR code that links to that specific batch's CoA, verifiable through Peptworks, so you and your customers can confirm authenticity and purity per batch.
Is KPV intended for human use?
No. KPV is a research-use-only (RUO) laboratory reagent for preclinical and in-vitro research. It is not a medicine, supplement, cosmetic or medical device, and it is not for human or animal consumption. Peptworks sells B2B to resellers and laboratories only, not to end consumers.
