The copper coordination chemistry of GHK-Cu enables controlled cellular copper delivery while preventing the formation of reactive oxygen species characteristic of free copper toxicity, with the peptide's binding affinity (log K = 16.1) positioning it perfectly within the physiological copper transport hierarchy to facilitate controlled metal transfer to enzymatic targets including lysyl oxidase (essential for collagen cross-linking) and superoxide dismutase (critical for antioxidant defense)
After the membrane was blocked with 5% skim milk TBST (20 mM Tris-Cl (pH 7.4), 150 mM NaCl, 0.1% Tween-20), it was incubated with streptavidin (SA) coupled to horseradish peroxidase (HRP) (1:1000, Pierce) and washed three times with TBST for 10 min
The goal is minimal agitation throughout the process
Glutathione Synthesis NAC provides cysteine, the rate-limiting amino acid that your body requires to manufacture glutathione inside every cell
The plasma was stored at 20C for analysis
