In vitro PARylation assays For the in vitro PARylation assay, purified GST-RSMC or GST-RSMC-16A was bound to Glutathione Sepharose 4B beads and incubated with the PARP1 enzyme (Sino Biological, 11040-H08B) for 1 h at 37 C in reaction buffer (50 mM TrisHCl pH 8.0, 150 mM NaCl, 10 mM MgCl 2 , 10% glycerol, 1 mM DTT) supplemented with or without 200 M NAD + , followed with three times wash with reaction buffer supplied with 300 mM NaCl
Beyond its role as a direct antioxidant, glutathione is the primary agent in Phase II liver detoxification, a critical process for clearing harmful substances from the body
While NAC (N-acetylcysteine) is sometimes used to boost glutathione, people with genetic polymorphisms in cysteine metabolism do not effectively convert it into glutathione
Combined with liposomal form, it is one of the most advanced supplementation methods available today
