KPV Nasal Spray

KPV Nasal Spray from Direct Anti Peptide is a rigorously manufactured, ≥98% purity tripeptide nasal spray formulation developed exclusively for use in qualified research environments. Designed for laboratory professionals investigating inflammatory biology, immune regulation, and mucosal peptide delivery, this product represents a high-quality, analytically verified research tool. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

KPV is a naturally occurring C-terminal tripeptide fragment derived from alpha-melanocyte-stimulating hormone (α-MSH). Its sequence — Lysine-Proline-Valine — confers significant biological research interest due to its demonstrated capacity to modulate pro-inflammatory cytokine cascades, interact with innate immune receptors, and exhibit broad-spectrum antimicrobial properties in controlled laboratory models. Direct Anti Peptide supplies KPV in a convenient nasal spray format, enabling researchers to explore intranasal peptide delivery kinetics and mucosal absorption dynamics within compliant research settings.

Peptide Structure & Amino Acid Sequence

KPV is a linear tripeptide composed of three canonical amino acid residues: L-Lysine (K), L-Proline (P), and L-Valine (V). This compact molecular architecture contributes to its relative stability compared to larger peptide chains, while its cationic charge profile at physiological pH is of particular interest in antimicrobial and membrane-interaction research. The tripeptide’s small molecular weight facilitates rapid diffusion across mucosal membranes, making the nasal spray delivery format a scientifically relevant model for transmucosal peptide absorption studies.

Purity & Analytical Verification (HPLC & MS)

Every batch of KPV Nasal Spray produced and supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to release. High-Performance Liquid Chromatography (HPLC) is employed to confirm peptide purity at ≥98%, ensuring minimal presence of truncated sequences, deletion peptides, or synthesis by-products. Mass Spectrometry (MS) verification confirms the correct molecular mass and sequence integrity of the KPV tripeptide. Certificates of Analysis (CoA) reflecting these results are available upon request, providing researchers with the documentation required for institutional compliance and experimental reproducibility.

Quality Control & Lyophilization Integrity

Prior to formulation into the nasal spray vehicle, the KPV peptide active substance is produced via solid-phase peptide synthesis (SPPS) and subjected to lyophilization to ensure long-term stability and preservation of structural integrity. The lyophilization process removes residual moisture under controlled vacuum conditions, minimizing oxidative degradation and peptide aggregation. Reconstitution into the spray carrier is performed under aseptic conditions, and the final product is subjected to sterility and particulate matter assessments consistent with research-grade standards. Each unit is batch-coded and traceable for full quality assurance transparency.

Safety, Handling & Laboratory Precautions

KPV Nasal Spray is supplied exclusively for use by trained research professionals operating within licensed laboratory environments. Standard laboratory personal protective equipment (PPE) — including nitrile gloves, safety eyewear, and a laboratory coat — should be worn when handling this product. Avoid inhalation of spray mist outside of controlled experimental contexts. This product is not intended for administration to humans or animals under any circumstances. Researchers should consult their institutional biosafety committee (IBC) and applicable local regulations before initiating any experimental protocol involving peptide compounds.

Reconstitution, Packaging & Storage

KPV Nasal Spray is supplied ready-to-use in a calibrated nasal spray dispenser. The product should be stored at 2°C to 8°C (refrigerated) upon receipt and protected from direct light and humidity. For extended storage beyond the recommended short-term window, freezing at -20°C is advised, with appropriate freeze-thaw cycle management to preserve peptide integrity. Do not expose to temperatures exceeding 25°C for prolonged periods. All packaging is designed to maintain product stability throughout transit and storage under recommended conditions.

Intended Research Use & Market Positioning

KPV Nasal Spray is positioned as a premium research reagent for scientists and institutions investigating inflammatory signaling, mucosal immunology, antimicrobial peptide mechanisms, gut barrier biology, and innate immune modulation. Preclinical research models have explored KPV’s interactions with NF-κB pathways, TNF-α immunoreactivity, and its potential relevance to conditions including inflammatory bowel disease models, skin barrier research, and wound healing assays. Direct Anti Peptide offers this product at a competitive best price, making it accessible for both individual researchers and institutional procurement teams seeking reliable, analytically verified peptide research tools.
