Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eResearch Context\u003cbr\u003e\u003c\/strong\u003eGHK-Cu is studied as a subject of interest across multiple converging molecular pathways in in-vitro and animal-model research. Investigations have examined its association with gene-expression modulation, reporting influence on over 4,000 human genes in research models. It is studied in research into collagen, elastin, and glycosaminoglycan biosynthesis pathways, VEGF-associated angiogenesis signalling, and antioxidant and inflammatory-pathway activity via superoxide dismutase induction. Its copper-chelating properties are examined in research into extracellular-matrix and connective-tissue biology, and its documented association with TGF-β signalling and stem-cell activation makes it a subject of interest in skin-biology, hair-follicle, and matrix-remodelling pathway research.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003cbr\u003e\u003c\/strong\u003e• Sequence: Validated by mass spectrometry (MS\/MS)\u003cbr\u003e• Purity: ≥ 99% by HPLC\u003cbr\u003e• Form: Liquid\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)\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQuality \u0026amp; Testing\u003c\/strong\u003e\u003cbr\u003eEvery batch is independently tested by a certified third-party laboratory.
