GHK-Cu: Whats the Difference
The following parameters were used: carbamidomethylation as a fixed modification, protein N -acetylation and methionine oxidation as variable modifications, a first search error window of 20 ppm, and a main search error of 4.5 ppm
Given that there was no difference in total GSH between Preparation Condition 1 and Preparation Condition 2, and that free GSH is significantly higher in Preparation Condition 1 than in Preparation Condition 2, these results suggest that EDTA-treatment more effectively prevents spontaneous oxidation of free GSH in plasma than does heparinization of samples
