What is KPV and what is Selank?
KPV is classified as Tripeptide alpha-MSH fragment; Selank as Synthetic heptapeptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
KPV
Tripeptide alpha-MSH fragment
KPV is a tripeptide composed of lysine, valine, and proline, corresponding to the C-terminal fragment (residues 11–13) of alpha-melanocyte-stimulating hormone (alpha-MSH). It is the smallest sequence retained from that parent peptide and is widely used as a compact reference compound in cellular signaling research, where its short chain length makes it convenient for controlled in-vitro work.

Synthetic heptapeptide
Selank is a synthetic heptapeptide, a seven-amino-acid chain built from the endogenous immunomodulatory tetrapeptide tuftsin with a C-terminal Pro-Gly-Pro extension added to increase stability. Verve supplies it as a high-purity research compound for neuroscience and peptide-signaling research.
full Selank profile →Which research models is each compound studied in?
KPV sits in recovery & gut research and Selank in mind & sleep research, so their listed models largely do not intersect. The table lists 5 reported research applications for KPV and 5 for Selank. Rows are per compound, not equivalences.
| KPV — reported research applications | Selank — reported research applications |
|---|---|
| Inflammatory-signaling research models (NF-κB pathway studies) | Regulatory-neuropeptide signaling research |
| Cytokine-expression research in cultured cells | GABAergic and monoaminergic pathway research models |
| Melanocortin-receptor and alpha-MSH fragment research | Neurotrophic gene-expression studies |
| Epithelial and mucosal-barrier research models | Tuftsin-analog structure–activity research |
| Structure–activity studies of short peptide fragments | Peptide-stability and degradation-kinetics research |
