KPV is a short tripeptide composed of the amino acids lysine (K), proline (P) and valine (V). It has gained attention in biomedical research for its anti-inflammatory, antimicrobial and tissue-regenerative properties. In many studies KPV has been shown to reduce cytokine production, inhibit neutrophil activation, and promote healing of skin and mucosal tissues. Because it is small, chemically stable, and inexpensive to synthesize, researchers often use KPV as a therapeutic agent in models of inflammatory bowel disease, periodontitis, wound healing, and even as an adjunct in vaccine formulations where modulation of the immune response is desirable.

KLOW Protocol

The KLOW protocol is a standardized method for viewcinema.ru evaluating the anti-inflammatory effects of KPV in vitro. The acronym stands for "Knock-down Lymphocyte-derived Oxidative-Stress-Related Wound-Healing." The steps are:

1. Cell Preparation – Primary human keratinocytes or murine macrophages are cultured to 80 % confluence in a 6-well plate.


2. Treatment – Cells receive KPV at concentrations ranging from 10 µM to 1000 µM for 24 h. A vehicle control (e.g., PBS) is included.


3. Stimulation – After pre-treatment, cells are stimulated with lipopolysaccharide (1 µg/mL) or TNF-α (20 ng/mL) to induce inflammation.


4. Readouts – Cytokine levels in the supernatant are measured by ELISA for IL-6, IL-8 and MCP-1. Reactive oxygen species production is quantified using a DCFDA fluorescence assay.


5. Data Analysis – Results are expressed as percent inhibition relative to the stimulated control. Statistical significance is assessed with one-way ANOVA followed by Tukey’s post-hoc test.

The KLOW protocol is widely adopted because it balances simplicity with reproducibility, allowing laboratories to compare their findings against a common benchmark.

Peptide Reconstitution Calculator

When working with peptide reagents like KPV, accurate reconstitution is critical. The Peptide Reconstitution Calculator helps researchers determine the correct volume of solvent needed to achieve a desired stock concentration. Users input:

• Desired final concentration (µM or mg/mL)


• Mass of peptide in milligrams


• Molecular weight of the peptide


• Volume of solvent to be used

The calculator outputs the exact amount of water, DMSO, or buffer required, along with the resulting molarity and a step-by-step reconstitution protocol. This tool is especially useful for peptides that are hygroscopic or prone to aggregation because it reduces errors that can arise from manual calculations.
