Peptide Name
KLOW (GHK-Cu + BPC-157 + TB-500 + KPV Blend)
Peptide Class
Synthetic peptide blend; copper(II) tripeptide complex (GHK-Cu) + cytoprotective peptide
fragment (BPC-157) + thymosin beta-4 analog (TB-500) + linear tripeptide (KPV)
Amino Acid Sequence
GHK-Cu: Gly-His-Lys coordinated with Cu²⁺
BPC-157: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
TB-500: Sequence corresponding to thymosin beta-4 (43 amino acids)
KPV: Lys-Pro-Val
(exact sequences and blend ratio are provided on the lot-specific COA)
Molecular Formula
Reported on COA for each component
(elemental composition depends on copper coordination state, counter-ion form, and hydration)
Molecular Weight
GHK-Cu: ~403–405 g/mol (complex form)
BPC-157: ~1.42 kDa
TB-500: ~4.96 kDa
KPV: ~341.4 g/mol
Combined (approximate): ~7.1–7.2 kDa (non-covalent blend)
(exact values confirmed by MS and reported on COA)
Peptide Type
Blend of linear synthetic peptides; includes one metal-coordinated tripeptide and three linear peptides
Chemical Structure
Four independent components: (1) GHK tripeptide chelating Cu²⁺via histidine and backbonecoordination; (2) BPC-157 linear pentadecapeptide; (3) TB-500 linear thymosin beta-4 analog;(4) KPV linear tripeptide. Components are not covalently linked and are supplied as a physicalblend.
Solubility
Generally soluble in water and common aqueous laboratory buffers; apparent solubility mayvary with pH, ionic strength, peptide concentration, and copper coordination chemistry.
Stability Characteristics
Lyophilized form: Store dry, protected from light and moisture, at−20 °C or below for long-termstability.
Reconstituted solutions: Prepare under sterile conditions; store in aliquots at cold temperatures and minimize repeated freeze–thaw cycles. Stability is buffer- and pH-dependent for each component; copper coordination may influence solution behavior.
Source Classification
Synthetic (solid-phase peptide synthesis with controlled copper complexation for GHK-Cu)
Purity Specification
≥98% (HPLC or enzymatic assay)
Identity confirmed by assays
Batch-specific Certificate of Analysis (COA) available
Reconstituted solutions
Prepare under sterile conditions; store in aliquots at cold temperatures and minimize repeated freeze–thaw cycles. Stability is buffer- and pH-dependent for each component; copper coordination may influence solution behavior.
