glutathione transferase activity assay Simple method for visual detection of S-transferase and inhibition using cysteamine-capped gold nanoparticles as colorimetric probes | Discover Metals Novus Biologicals™ Glutathione S-Transferase/GST Activity

These patches are usually symmetrical and may vary in size and intensity

(5) IIRI + MET + Abx group: administered oral antibiotics (ampicillin 1 g/L, neomycin 1 g/L, metronidazole 1 g/L, and gentamicin 160 mg/L) combined with metformin in drinking water for one week prior to IIRI

Alternatively, endocytosis and/or transcytosis of GSH transporter-targeted ligands may be assayed by in vivo bioimaging techniques using for instance near-infrared dyes or radioactive labels conjugated thereto, resulting in at least 10, 20, or 50% enhanced retention in CNS area of the ligand at given time-points (based on region of interest (ROI) pixel quantification), as compared to appropriate control conditions (e.g., comparison to reference compounds lacking GSH moieties)

gradual dose tapering over several days is recommended
