{"product_id":"copper-pep","title":"Copper-Pep","description":"\u003cp\u003eCopper-Pep is a copper complex of the three-amino-acid peptide glycine–histidine–lysine. It brings peptide chemistry and metal coordination together, with research examining how a short amino acid sequence binds copper and interacts with its molecular surroundings.\u003c\/p\u003e\n\u003ch2\u003eAbout Copper-Pep\u003c\/h2\u003e\n\u003cp\u003eThe peptide portion, abbreviated GHK, provides the binding environment for copper. Coordination studies examine the complexes that form in solution and the conditions that influence their stability. Comparing GHK with related sequences also helps researchers investigate how individual amino acid changes affect copper binding.\u003c\/p\u003e\n\u003cp\u003ePublished chemical studies have combined visible-light spectroscopy, electron paramagnetic resonance and calorimetry. These methods provide complementary information about the copper environment and the energetics of complex formation. Together, they connect molecular structure with measurable chemical behavior. \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/11325542\/\"\u003eRead the copper coordination study\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eThe research also extends to interactions with larger proteins. Work with human serum albumin identified complexes involving GHK, copper and histidine sites on the protein. This adds a further research question: how does copper coordination change when a small peptide becomes part of a more complex molecular environment? \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/34730942\/\"\u003eExplore the albumin interaction study\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eQuality, Purity and Documentation\u003c\/h2\u003e\n\u003cp\u003eEvery lot of Copper-Pep is produced to a minimum purity specification of 99%, verified by high-performance liquid chromatography (HPLC) with mass spectrometry (MS) confirmation of molecular identity. A lot-specific Certificate of Analysis (COA) accompanies every batch and documents the analytical results for the exact material supplied, so laboratories can qualify the material against their own acceptance criteria before use.\u003c\/p\u003e\n\u003ch3\u003eAvailable sizes\u003c\/h3\u003e\n\u003cp\u003eCopper-Pep is supplied as a lyophilized (freeze-dried) powder in sealed vials in 50mg and 100mg formats. Lyophilization removes water under vacuum at low temperature, producing a stable dry preparation suited to controlled laboratory storage and accurate gravimetric preparation of experimental solutions.\u003c\/p\u003e\n\u003ch3\u003eStorage and handling\u003c\/h3\u003e\n\u003cp\u003eStore lyophilized vials at -20°C or below, protected from light and moisture. Allow sealed vials to equilibrate to room temperature before opening to limit condensation inside the vial. Once opened, handle with clean laboratory technique, minimize exposure to ambient humidity, reseal promptly, and record the lot number in laboratory documentation for traceability.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFor qualified in-vitro laboratory research only.
