In scientific research, this compound is studied as a model compound for the coordination chemistry of peptide-metal complexes and as a reference standard in analytical work. The product is offered as a ready-to-use aqueous formulation of 35 ml, exclusively for laboratory and research purposes.<\/p>\n<h2>Czym jest GHK-Cu?<\/h2>\n<p>GHK-Cu is the copper(II) complex of the naturally occurring tripeptide GHK, with the amino acid sequence glycine-histidine-lysine (Gly-His-Lys). The metal ion is fixed in a defined coordination pocket: the bonding mode is typically described as a planar arrangement of three nitrogen donors, namely the \u03b1-amino group of the N-terminal glycine, the deprotonated amide nitrogen atom of the first peptide bond, and the imidazole of the histidine. The basic lysine side chain remains outside this arrangement and keeps the complex highly water-soluble. Because this geometry is sharply defined, GHK-Cu is considered a classic model system for copper binding to short peptides in bioinorganic chemistry.<\/p>\n<p>In research models, the complex is primarily studied as an exchangeable copper reservoir: in vitro, under defined conditions, the coordinated ion can be transferred to competing ligands or to copper-dependent enzymes such as lysyl oxidase and superoxide dismutase. Additionally, the copper(II) center makes the formulation easy to monitor spectroscopically: alongside the UV absorption of the imidazole, a weak dd transition occurs in the visible region, which explains the blue color and makes the integrity of the complex measurable. In cell-free systems and fibroblast cultures, the redox balance around the coordinated ion is further investigated. Consequently, GHK-Cu is used as a model compound and reference substance within scientific research.<\/p>\n<h2>Obszary bada\u0144<\/h2>\n<p>W kontek\u015bcie laboratoryjnym GHK-Cu wyst\u0119puje mi\u0119dzy innymi w nast\u0119puj\u0105cych obszarach badawczych:<\/p>\n<ul>\n<li>Chemia koordynacyjna bionieorganiczna: sta\u0142e stabilno\u015bci, stechiometria i geometria kompleks\u00f3w miedzi(II)-peptyd.<\/li>\n<li>Badania enzymatyczne nad enzymami zale\u017cnymi od miedzi, w tym oksydaz\u0105 lizylow\u0105 i dysmutaz\u0105 ponadtlenkow\u0105, w uk\u0142adach bezkom\u00f3rkowych.<\/li>\n<li>Modele hodowli kom\u00f3rkowych umo\u017cliwiaj\u0105ce konwersj\u0119 sk\u0142adnik\u00f3w macierzy zewn\u0105trzkom\u00f3rkowej do kultur fibroblast\u00f3w.<\/li>\n<li>Formulation research into metallopeptides in an aqueous matrix, including pH-dependent complex stability.<\/li>\n<li>Opracowywanie i walidacja metod analitycznych (HPLC, UV-vis, LC-MS) z formulacj\u0105 jako materia\u0142em odniesienia.<\/li>\n<li>Stability and permeation studies on membrane models under controlled light and temperature conditions.<\/li>\n<\/ul>\n<p>Ka\u017cde z tych zastosowa\u0144 obejmuje kontrolowane badania laboratoryjne lub badania na modelu przedklinicznym.<\/p>\n<h2>GHK-Cu Serum in our research assortment<\/h2>\n<p>Within our range, this product falls under the category of ready-to-use aqueous investigational formulations in vial form. While this formulation focuses on metal coordination and the associated bioinorganic chemistry, other components within the same product line have been specifically chosen to cover peptide-receptor interactions or enzymatically mediated targets. These products share the aqueous serum base and vial packaging, but differ fundamentally in molecular class and investigated mechanism.<\/p>\n<h2>Specyfikacje<\/h2>\n<table>\n<thead>\n<tr>\n<th>Specyfikacja<\/th>\n<th>Warto\u015b\u0107<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Pr\u00f3bka<\/td>\n<td>GHK-Cu (kompleks glicylo-L-histydylo-L-lizyny i miedzi(II))<\/td>\n<\/tr>\n<tr>\n<td>Synonimy<\/td>\n<td>tripeptyd miedzi-1; Cu-GHK<\/td>\n<\/tr>\n<tr>\n<td>Sekwencja<\/td>\n<td>Gly-His-Lys<\/td>\n<\/tr>\n<tr>\n<td>Numer CAS<\/td>\n<td>89030-95-5 (kompleks miedzi(II)) 49557-75-7 (peptyd GHK)<\/td>\n<\/tr>\n<tr>\n<td>Wz\u00f3r cz\u0105steczkowy \/ masa (peptyd GHK)<\/td>\n<td>C<sub>14<\/sub>H<sub>24<\/sub>N<sub>6<\/sub>O<sub>4<\/sub> \/ 340,38 Da<\/td>\n<\/tr>\n<tr>\n<td>Identyfikator CID PubChem<\/td>\n<td>378611 (Cu-GHK) 342538 (GHK)<\/td>\n<\/tr>\n<tr>\n<td>Klasa<\/td>\n<td>Metalopeptyd; kompleks miedzi(II) z tripeptydem<\/td>\n<\/tr>\n<tr>\n<td>Formularz<\/td>\n<td>Serum wodne z konserwantem<\/td>\n<\/tr>\n<tr>\n<td>Zawarto\u015b\u0107 na butelk\u0119<\/td>\n<td>35 ml<\/td>\n<\/tr>\n<tr>\n<td>Sk\u0142adowanie<\/td>\n<td>Przechowywa\u0107 w ch\u0142odnym miejscu, chroni\u0107 przed bezpo\u015brednim \u015bwiat\u0142em.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Kszta\u0142t, obs\u0142uga i przechowywanie<\/h2>\n<p>The product is supplied as a ready-to-use aqueous formulation of 35 ml in a vial. No solid needs to be weighed: the active substance is already stabilized in the matrix, together with a preservative that inhibits microbial growth.
