KPV Peptide Vial

Product Overview

Direct Anti Peptide proudly offers the KPV Peptide Vial as a premium-grade, brandless research compound for qualified laboratory professionals and institutional researchers. KPV — the tripeptide sequence Lysine-Proline-Valine — is a biologically active C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH). This short yet structurally significant peptide has attracted considerable scientific interest due to its involvement in cellular inflammatory signaling, mucosal barrier integrity, and tissue-repair research models. Supplied in a sterile, sealed glass vial in lyophilized powder form, this product is engineered for consistency, stability, and research reproducibility.

Peptide Structure & Amino Acid Sequence

KPV is a tripeptide composed of three amino acid residues: Lysine (K) – Proline (P) – Valine (V). This sequence corresponds directly to the C-terminal tri-amino acid fragment of the endogenous neuropeptide α-MSH, which is itself derived from the proopiomelanocortin (POMC) precursor protein. The compact, linear structure of KPV confers notable biochemical stability relative to the full α-MSH sequence, making it a preferred candidate in controlled in vitro and ex vivo research settings. Its minimal chain length facilitates targeted receptor-interaction studies, particularly those examining melanocortin receptor subtypes and downstream anti-inflammatory signaling cascades.

Purity & Analytical Verification (HPLC & MS)

Every KPV Peptide Vial supplied by Direct Anti Peptide achieves a minimum purity of ≥98%, verified through rigorous analytical testing. High-Performance Liquid Chromatography (HPLC) is employed to confirm peptide purity and identify the presence of any residual synthesis by-products. Mass Spectrometry (MS) analysis independently validates the molecular identity and structural integrity of each batch. These dual-verification protocols ensure that researchers receive a product that meets the highest standards of analytical quality, supporting the reproducibility and validity of their experimental data. A Certificate of Analysis (CoA) reflecting these results is available upon request.

Quality Control & Lyophilization Integrity

Lyophilization — the process of freeze-drying the peptide solution under controlled vacuum conditions — is the gold standard for preserving peptide bioactivity and extending shelf life. Each KPV vial undergoes a validated lyophilization cycle to remove residual moisture while maintaining the structural conformation of the peptide. Post-lyophilization, vials are sealed under inert gas and subjected to quality control inspection for visual appearance, moisture content, and sterility. This rigorous process ensures that each vial dispatched from Direct Anti Peptide retains its full analytical integrity from production through delivery to your laboratory.

Safety, Handling & Laboratory Precautions

KPV Peptide Vials are intended exclusively for use by trained research professionals operating within a properly equipped laboratory environment. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and lab coat — should be worn at all times when handling this compound. Researchers should consult the relevant Safety Data Sheet (SDS) prior to use. This product has not been evaluated for safety in biological systems and must not be used in any application involving living organisms, human subjects, or animals. All waste materials should be disposed of in accordance with applicable institutional and regulatory guidelines.

Reconstitution, Packaging & Storage

The KPV Peptide Vial is supplied as a lyophilized powder in a sealed, sterile glass vial designed to protect the compound from moisture, oxygen, and environmental contaminants during storage and transit. For laboratory reconstitution, researchers should consult peer-reviewed literature and institutional SOPs to select an appropriate research-grade solvent or buffer compatible with their specific assay requirements. Once reconstituted, the solution should be aliquoted and stored according to validated protocols to minimize freeze-thaw degradation. Unopened vials should be stored at −20°C in a dry, dark environment. Proper storage conditions are essential to maintaining ≥98% purity over the stated shelf life.

Intended Research Use & Market Positioning

The KPV Peptide Vial is positioned as a high-value research tool for scientists investigating inflammatory signaling pathways, mucosal tissue biology, wound-healing mechanisms, and gut epithelial barrier function. Its structural relationship to α-MSH makes it particularly relevant in studies examining melanocortin receptor activity and downstream immunomodulatory effects at the cellular level. Direct Anti Peptide supplies this compound exclusively for in vitro and ex vivo research applications. It is not intended for use as a pharmaceutical, nutraceutical, food additive, or therapeutic agent of any kind.
