What is KLOW Blend?
KLOW Blend is a peptide blend of four named components, GHK-Cu, TB-500, BPC-157 and KPV, supplied together in a single vial as a lyophilized powder for laboratory research. The labeled quantities are 50mg GHK-Cu, 10mg TB-500, 10mg BPC-157 and 10mg KPV. It is handled in the laboratory as a water soluble reference material.
KLOW Blend structure and components
GHK-Cu is the copper(II) complex of the tripeptide Gly-His-Lys, and the copper complex gives the material its blue tint.
TB-500 corresponds to a seven residue fragment of thymosin beta-4, carried as an N-terminally acetylated sequence.
BPC-157 is a linear 15 residue peptide, Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, molecular weight 1419.54 Da.
KPV is the tripeptide Lys-Pro-Val, corresponding to the C-terminal three residues of alpha-MSH. The four components differ widely in size and polarity and are resolved as separate peaks in reversed phase chromatography, with LC-MS confirming the identity of each.
Where this material appears in the literature
Published work on the components of this blend is preclinical and in vitro. It appears in the literature chiefly in copper peptide research, peptide signaling studies, soft tissue models and cell culture studies, and as an analytical subject in peptide stability and formulation work. Viva Amino supplies the material for that kind of laboratory investigation and makes no claim about what it does in any living subject.

KLOW Blend is held under Research Blends, alongside the BPC-157 / TB-500 Blend. BPC-157 is also supplied on its own under Peptide Research.
Analysis and certification
Every lot is analyzed by an independent laboratory before release, using RP-HPLC for purity and LC-MS for identity confirmation. The certificate of analysis is published against the lot number rather than against the product page, so the document you read is the document for the vial you receive. The lot number printed on the vial label is the link between the two.
Purity specification
Lots are released against a ≥98% purity specification, determined by RP-HPLC peak area. A specification is a release threshold, not a description of every lot. The measured figure for the lot you receive is stated on its certificate of analysis and may sit above the specification.
Where a measured figure and the specification differ, the certificate is the record that applies to your material. Analytical figures relate to the lot they are published against and carry no implication of suitability for any purpose beyond laboratory research.
Research use only
Viva Amino supplies this material as a reference standard for laboratory research. It is not supplied for any use in humans or animals, it is not a drug, dietary supplement, food or cosmetic, and nothing on this page describes or implies any such use. Sale is restricted to persons aged 21 or over who are qualified researchers or who purchase on behalf of a research institution, laboratory or business.

Characterization. Values above describe the blend as supplied. The figures for the lot you receive, including measured purity, are stated on its certificate of analysis.
How this material is tested
Two separate analyses are carried out on every lot before release, and both appear on the certificate.
- RP-HPLC, for purity. Reversed phase high performance liquid chromatography separates the material by hydrophobicity. The main peak is integrated against total peak area, and that ratio is the purity figure reported on the certificate.
- LC-MS, for identity. Liquid chromatography coupled to mass spectrometry confirms that the mass of the main peak matches the expected mass for the compound, which is what distinguishes the correct sequence from a closely related one.
A complete certificate carries the compound name, the lot number, the test date, the method, the measured purity and the name of the laboratory. If any of those is missing, or the lot number on the vial does not match the certificate, contact us before using the material.
Storing KLOW Blend
Lyophilized material is shipped cold and should be moved into freezer storage on arrival. Store the sealed vial dry at −20°C or below, protected from light and moisture. Returned promptly to those conditions, the dry solid is the most stable form this material takes.
Preparing stock solutions
Prepare stock solutions in sterile water or an appropriate aqueous buffer at a concentration suited to your assay, expressed in mg/mL. Allow the vial to reach room temperature before opening, add solvent down the vial wall rather than directly onto the solid, and let the material dissolve without vigorous agitation. KLOW Blend dissolves readily in water at the concentrations used for analytical work.
Solutions are less stable than the lyophilized solid. Prepare close to the point of use, hold at 2 to 8°C for short periods only, and aliquot before freezing so the solution is not repeatedly frozen and thawed.
On arrival
Check that the vial is intact and sealed, that the compound name and labeled quantity match your order, and that the lot number on the label matches the certificate published for it. If anything does not match, or the packaging has clearly failed in transit, contact us before using the material. Problems visible on arrival should be reported within 7 days so that a carrier claim remains possible.
Handling and disposal
Assess the hazards of this material before handling it and use appropriate controls and protective equipment. It has not been characterized toxicologically and should be treated as potentially hazardous. Anyone handling it should be trained for the work.
Dispose of unused material, vials and packaging lawfully and in line with your institution’s waste procedures.
Record keeping
Record the lot number in your notes at the point of first use, alongside the date the vial was opened and the concentration of any stock prepared. Certificates are published against the lot number rather than the product, so the lot number is the only reliable link between your results and the analytical data for the material that produced them. If a question arises about a result months later, that link is what keeps the work auditable.
