So, now I know

Crystallization of Pt GSTF8 in presence of ()-catechin and GSH Purified Pt GSTF8 in 30 mM Tris, pH 8, 200 mM NaCl, 1 mM EDTA was concentrated to 12.4 mg ml 1 using an Amicon Ultra-4 device (10 kDa cut-off) (Merck Millipore) and supplemented with 1 mM GSH and 25 mM ()-catechin immediately before crystallization

While B12 injection side effects are rare, some individuals may experience mild discomfort or redness at the injection site

In older adults, GlyNAC supplementation has been studied for effects on glutathione levels, oxidative stress, mitochondrial function, inflammation, muscle strength, and cognition.34 While the results have generated significant interest, it's not yet clear how much of the observed benefit comes from NAC itself versus the combination of NAC and glycine
