Scientific profile

KPV at a glance

KPV keeps the calming, anti-inflammatory side of the hormone alpha-MSH but not its effect on skin pigment. In lab studies it's been shown to dampen a key inflammation 'switch' inside cells (called NF-κB) and to lower several inflammation signals. In the gut, it can be taken up through a specific transporter, which makes it interesting for targeting inflamed intestinal tissue.

01

What is KPV?

Alpha-MSH is a small natural hormone with two jobs: affecting skin pigment and calming inflammation. KPV is just its final three building blocks (lysine, proline and valine), and it keeps much of the anti-inflammatory side while dropping the pigment effect.

Its tiny size makes it unusually stable and cheap to make at high purity, and lets it slip into cells through a transporter (called PepT1) that's common in the gut lining.

02

What researchers study KPV for

The main focus in KPV research is that inflammation switch, NF-κB. In cell layers that have been deliberately inflamed, KPV has been shown to quieten this switch and reduce the inflammation signals it would normally turn on.

Other work looks at how well the gut barrier holds together, by measuring the 'tightness' of cell layers. A further strand studies the PepT1 transporter specifically, since it offers a route to deliver KPV straight into inflamed gut tissue in colitis models.

03

How to store and prepare KPV

KPV dissolves easily in water. Mix it with bacteriostatic water, swirl gently, and use the clear colourless solution within 30 days when kept in the fridge (2–8°C).

Because it's such a short peptide, KPV breaks down more quickly in solutions that contain serum, so researchers often prepare fresh dilutions on the day they're used.

Certificates of analysis

Every batch tested. Every result published.

Samples from each KPV batch are sent to an independent, accredited UK laboratory. Purity is measured with a technique called HPLC, and identity is confirmed by mass spectrometry, before the batch is released.

Every release is held to the same specification, so a repeat order behaves like the last one.

Answers

KPV questions, answered

Can't find what you need? Our UK team answers technical enquiries within one working day.

Is KPV third-party tested?

Yes. Every batch of KPV is checked by an independent UK laboratory that's accredited to the ISO/IEC 17025 standard. They confirm its purity (using a technique called HPLC) and its identity (using mass spectrometry). The certificate for the exact batch you receive is published on this page before we put it on sale.

Where is it made and shipped from?

Everything (making the peptide, filling the vials and quality-checking each batch) happens in the UK at our facility on Alderley Park, the country's largest life-sciences campus. Your order is picked, packed and posted from the same site, so nothing crosses a border before it reaches you.

How quickly will my order arrive?

Orders placed before 3pm, Monday to Friday, are sent out the same working day on a tracked 24-hour UK service. Delivery is free on orders over £100. Everything ships in plain, unbranded packaging.

What does 99% purity actually mean?

It means at least 99% of what's in the vial is the peptide itself, with almost no leftover by-products. We measure this with a lab technique called HPLC, and only release batches that reach 99% or higher. The exact figure for your batch is printed on its certificate.

How does KPV come packaged?

KPV arrives as a freeze-dried powder in a sealed glass vial, with a flip-off cap and a tamper-evident seal so you know it hasn't been opened. You'll need bacteriostatic water to mix it (sold separately).

Can I save money by buying more than one vial?

Yes. Two vials save you 10% and three vials save 20% against the single-vial price.

Do I get a Certificate of Analysis with every order?

Yes. A certificate comes with every batch and can be downloaded from this page. It shows the batch number, the date it was made, the purity result, confirmation of identity, appearance, water content and a contamination (endotoxin) check.

Is this product for human use?

No. Everything we sell is supplied strictly as a research-grade compound for laboratory study by qualified researchers. These products are not medicines and are not intended for human or animal consumption, injection, diagnosis or treatment.
