KPV Tripeptide Lys-Pro-Val Synthetic Lyophilized Research Peptide

Product Basic Profile

Lys-Pro-Val Tripeptide, abbreviated as KPV, is fully synthetic short polypeptide composed of three amino acid residues: Lysine, Proline and Valine. The whole production adopts automatic solid-phase peptide synthesis equipment for peptide chain assembly, followed by multi-step gradient elution HPLC purification to remove truncated peptide fragments and synthesis by-products. The finished raw material is white loose lyophilized powder with stable chemical structure, low endotoxin residue and excellent water solubility. It can be fully dissolved in deionized water and pH7.2 PBS buffer to form transparent homogeneous liquid samples for isolated cell incubation and biomolecular binding tests in laboratory environment.

This product is exclusively defined as special raw material for in vitro isolated lab research only. All human-related application scenarios are strictly prohibited, including oral intake, subcutaneous injection, external skin coating, clinical sample preparation, cosmetic raw material blending and other human-oriented usage modes.

Standard Storage & Operation Operating Guidelines

Long-term storage operation: Tightly seal glass vials or aluminum foil bags, store at constant temperature of -20℃ away from light and moisture, minimize repeated freeze-thaw cycles to prevent peptide chain hydrolysis and degradation. Temporary storage after opening: Keep the container tightly sealed and store under 2–8℃ environment, finish all experimental usage within 30 days after opening to avoid moisture absorption and mixed impurity pollution of samples. Standard dissolution operation rule: Prepare fresh peptide aqueous solution with sterile ultrapure water or pH7.2 PBS buffer before each experiment, discard residual diluted liquid after single use, long-term storage of diluted peptide solution is strictly prohibited. Transportation environment requirement: Avoid direct sunlight and long-time exposure to high temperature environment during whole cold chain transportation process.
