Description
Engineered nanodelivery systems to improve DNA vaccine technologies
Upon subtraction of the on and off conditions, the edited-GSH resonance at 2.95 ppm is observed (Figure 1)

In the reaction mechanism of monothiol Grxs, the reduction of glutathionylated proteins (PrSSG) begins with a nucleophilic attack of the N -terminal cysteine

It is simply using proper laboratory technique
