{"product_id":"ghk-cu","title":"GHK-CU","description":"\u003cp\u003e\u003cstrong\u003eGHK-Cu\u003c\/strong\u003e is a naturally occurring copper-binding tripeptide complex consisting of the peptide glycyl-L-histidyl-L-lysine chelated to a copper (II) ion, found endogenously in human plasma, saliva, and urine. Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eResearch Context\u003c\/strong\u003e\u003cbr\u003eGHK-Cu is studied in in-vitro and animal-model research across several converging molecular pathways. It is investigated as a modulator of gene expression, with reported associations to over 4,000 human genes in research models. Reported research subjects include collagen, elastin, and glycosaminoglycan synthesis pathways, VEGF-associated angiogenesis signalling, and antioxidant and inflammation-related pathways involving superoxide dismutase. Its copper-chelating properties are examined in relation to extracellular matrix remodelling pathways, and its documented interactions with TGF-β signalling and stem-cell-associated markers make it a subject of interest in skin biology, extracellular matrix research, hair follicle research, and related molecular investigation.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e• Sequence: Validated by mass spectrometry (MS\/MS)\u003cbr\u003e• Purity: ≥ 98% by HPLC\u003cbr\u003e• Form: Lyophilized powder\u003cbr\u003e• Molecular Weight: 340.4 Da (free peptide); 403.9 Da (copper complex)\u003cbr\u003e• Storage: 2 – 8 °C, keep dry and away from light\u003cbr\u003e• Shelf Life: 24 months from manufacture date (sealed)\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eQuality \u0026amp; Testing\u003c\/strong\u003e\u003cbr\u003eEvery batch is independently tested by a certified third-party laboratory.
