Aging (Reduced Synthesis Capacity) As you age, production of glutathione declines due to: Reduced activity of gamma-glutamylcysteine ligase (GCL) , the rate-limiting enzyme in glutathione synthesis Decreased cellular energy (ATP) to fuel glutathione recycling Lower levels of precursor amino acids (especially cysteine and glycine) Studies show glutathione levels drop 10-15% per decade after age 40 [3]

Although a limitation is that halogenated compounds containing chloride ions (e.g., Tris-HCl, NaCl) cannot be used in the lysis or binding buffers, the system offers the advantage of one-step purification (~1 h) with high specificity, as has been reported in several applications involving recombinant protein expression and purification using this system [43,44,165,166]
