KPV Peptide Australia: Buy KPV Online

Shop KPV Peptide Australia Stock as a 10 mg Vial With Full Lot Data

Order KPV for work on inflammatory signalling in epithelial cells, with three residues, a simple synthesis and an identity anyone can confirm on the certificate. At 342 g/mol, one 10 mg vial holds about 29 micromoles, a long run of experiments for a small outlay.

What Is KPV Peptide?

KPV is a tripeptide made of lysine, proline and valine, the final three amino acids of alpha-MSH (alpha-melanocyte-stimulating hormone), studied because it keeps much of that hormone's anti-inflammatory activity without its role in pigmentation. Alpha-MSH itself is 13 residues long and is cut from a larger precursor, pro-opiomelanocortin (POMC), which cells in the pituitary, skin and immune system all process. In the native hormone the valine end is amidated. The research tripeptide we supply is the free acid form, which is the version used in most cell papers.

How KPV works in research models

Most peptides in this catalogue act by binding a receptor on the cell surface. KPV seems to work from inside the cell instead. Alpha-MSH signals through melanocortin receptors, yet in a 2008 Gastroenterology paper, Guillaume Dalmasso, Didier Merlin and colleagues found that KPV raised no cAMP in Caco-2 intestinal cells that carry two of those receptors, MC3R and MC5R. What mattered was PepT1, a transporter that normally pulls dietary di- and tripeptides into the small intestine lining and becomes more abundant in an inflamed colon. Once carried inside, KPV at 10 nanomolar cut NF-kappa B activation and the phosphorylation of three MAP kinases (ERK1/2, JNK and p38), and the cells released less IL-8, a chemokine that calls neutrophils to a site of inflammation. Flooding the transporter with a competing dipeptide, glycyl-leucine, abolished the effect.

• Mouse models in that paper: DSS colitis over 8 days and TNBS colitis, with KPV given at 100 micromolar in drinking water.
• Readouts: weight loss, colon histology, myeloperoxidase activity and cytokine levels.
• Follow-up work: the Merlin group later loaded KPV into colon-targeted nanoparticles to reach inflamed tissue at lower amounts.

Keratinocytes express their own melanocortin machinery and inflammatory cascades, which makes them the second home for this compound and the basis of most KPV peptide anti-inflammatory skin studies. Every finding so far is preclinical, and what we sell is a reagent to reproduce and extend it. Other inflammation probes are listed in our immune signalling peptide range.

The point we would stress to any lab: check whether your cell line expresses PepT1 before you design around KPV. A line with little or no transporter may show a weak or absent response that says more about uptake than about the peptide, so a quick PepT1 expression check, and a Gly-Leu competition arm, will save a confusing first experiment.

Where KPV Stands in Australia Today, and What the Vial Contains

The anti-inflammatory activity of this alpha-MSH tail was first reported in 1989 by Hiltz and Lipton in the United States, who found that the 11 to 13 fragment reduced swelling in a mouse ear inflammation model. More than three decades later the tripeptide is still a research tool. What arrives from us is a 3 mL glass vial containing 10 mg of fine white powder, nothing more, and the same molecule is also one of the four components of the KLOW blend, for labs that run the full combination.

Is KPV legal in Australia?

The honest answer is narrower than most listings admit. As of October 2026 KPV has no approved therapeutic use here, and we could not confirm a dedicated, named entry for it in the Poisons Standard, unlike BPC-157 or TB-500. That gap does not make it a consumer product. The TGA's April 2026 advisory on unapproved peptide products, and its guidance that "research only" wording does not change the law when goods are supplied for people, apply to any peptide offered for use in humans. Athletes face a separate rule, since WADA's S0 category catches pharmacological substances with no current government approval for human therapeutic use.

So KPV peptide Australia listings are research supply, full stop. AminoBlend keeps the 10 mg vial in Australian stock as a laboratory reagent, available to order online by adults 18 and over, and never for human or veterinary use. If you plan to buy KPV in Australia for a combined protocol, set it against the KLOW 80 mg blend first, and check the lot in our certificate archive before ordering.

Order KPV in One 10 mg Fill, Lot Tracked

KPV comes in one size, the 10 mg vial at $59, or $5.90 per mg, among the lowest per-milligram prices in our recovery peptides range. Because the molecule is so light, that milligram goes much further in molar terms than the same mass of a long peptide.

Shop several units in one order and they stay on a single lot wherever stock allows, removing one variable between two series of experiments. KPV is sold only to adults aged 18 or over, who confirm their age and laboratory purpose when they check out.

Buy KPV With Structure, Purity and a Lot Certificate on File

A swapped or missing residue in a three amino acid chain leaves a powder that looks exactly the same, so the mass line is what counts. The certificate should show a measured mass near 342.4 g/mol and an HPLC chromatogram with one main peak, its purity value printed beside it. All three residues are in the L configuration, with a free N-terminal amine and a free C-terminal acid.

Order after reviewing that data, which is filed under its lot code in the COA library, then match it to the label on arrival.

Short peptides also make purity easier to interpret. With so few residues there are only a handful of plausible impurities, such as a deletion dipeptide or a racemised valine, and these separate cleanly from the main peak on a reversed-phase column. That makes KPV one of the simplest compounds in our catalogue to document in a methods section, and a sensible first purchase for a lab setting up its own identity checks on incoming reagents. It also answers which is the best KPV peptide to stock, since the one you can verify line by line is the one worth keeping.

Shop KPV for Skin and Gut Cell Research

Work on KPV peptide for skin models uses keratinocyte cultures and topical inflammation studies in rodents, where cytokine release and NF-kappa B activity are the usual readouts. Gut research leans on Caco-2 monolayers and colitis models instead. Both lines treat the tripeptide as a probe of inflammatory signalling, not as a finished product, and every result so far comes from cells and animals. Any KPV peptide skin benefits described to date are laboratory readouts, such as lower cytokine release in cultured keratinocytes and reduced inflammation scores in rodent skin, and our peptides for skin research guide places them beside other skin model compounds.

Order KPV Online From Anywhere in Australia and Store the Vial

Hunting for a KPV stockist in your city, or for research peptides on the Gold Coast, is unnecessary. Our online store supplies research groups across Australia from a single local stock, and anything ordered ahead of the 3pm cut-off on a working day is sent out that day under tracking. Delivery details by state are on the delivery information page.

Buy bacteriostatic water in the same cart, as KPV is hydrophilic and dissolves without fuss. Bring the vial to room temperature, add the diluent against the glass and turn it gently. With 2 mL in the 10 mg vial you have 5 mg/mL, and the reconstitution calculator covers every other volume.

The powder keeps at -20 °C, dry and in the dark. Once dissolved, keep it at 2 to 8 °C, divided into aliquots so the stock solution is not warmed and chilled repeatedly.

Other Names for KPV

The same tripeptide is written KPV, Lys-Pro-Val, H-Lys-Pro-Val-OH, lysyl-prolyl-valine or alpha-MSH (11-13). Some papers describe it as the C-terminal tripeptide of alpha-MSH. Every label refers to the chain with CAS 67727-97-3 and formula C16H30N4O4.

Related terms come from its biology, including POMC, melanocortin, PepT1 (SLC15A1), NF-kappa B and IL-8. KPV should not be confused with melanotan analogues, which keep the receptor-activating core that KPV lacks.

Buy KPV or BPC-157 for Intestinal Models

Both turn up in intestinal models, which is why labs compare them before buying. BPC-157, fifteen residues long and drawn from a gastric protein, is studied for angiogenesis, nitric oxide and tissue repair in rodents, while KPV is a hormone-derived tripeptide used to probe inflammatory signalling inside epithelial cells. If the question concerns barrier cells and cytokines, order KPV, and if it concerns blood supply and healing tissue, BPC-157 fits better.

Shop the KLOW blend when a protocol is already fixed at that blend's ratio, since KPV is one of its four components. For studying the tripeptide alone, the single vial is the right purchase.
