The batch of the ARPE-19 cells used in this study was validated using short tandem repeat (STR) analysis by Cobioer Biosciences (Nanjing, China)
As we share on our HRT & Peptide Therapies page, these peptides work as targeted messengers, triggering effects right where you want them
The presence of Tf) in the eluates is likely due to leaching from the holo-human transferrin Affi-resin, which often occurs in this type of analysis and was not used in the PANTHER analyses

Key effects include: Delivers bioavailable copper to activate critical copper-dependent enzymes Stimulates collagen, elastin, and glycosaminoglycan production, helping skin, tendons, and connective tissues regenerate Accelerates wound healing and supports remodeling of old or fibrotic tissue Regulates matrix metalloproteinases (MMPs) to balance tissue breakdown and rebuilding Reduces inflammation by lowering cytokines such as TNF-, IL-6, and TGF- Provides antioxidant protection by boosting copper-dependent enzymes Supports hair follicle health and dermal papilla cell activity Influences gene expression related to repair, regeneration, and cell protection Improves tissue resilience in skin, muscle, and joint structures May support cognitive and neural protection through antioxidant and anti-inflammatory mechanisms Key Research Areas and Potential Benefits 1
