• Thiocholine reacts with the Ellman reagent dithionitrobenzoic acid (DTNB) to produce the anion of 5-thio-2-nitrobenzoic acid, which forms a yellow color that is measured spectrophotometrically at 412 nm. (cdc.gov)
  • The samples were mixed with 5,5´-dithiobis-(2-nitrobenzoic) acid (DTNB) resulting in yellow colored drops forming. (nel.edu)
  • Glutathione belongs to the family of small-molecular weight antioxidants like ascorbic acid, cysteine, α-tocopherol, uric acid, etc. (nel.edu)
  • Reduced glutathione (GSH) solutions were prepared in water in the concentration 0-16 mmol/L. Other small-molecular weight antioxidants like 0.25 mmol/L ascorbic acid, 0.15 mmol/L TROLOX and 0.02 mmol/L N-acetyl-cysteine (NAcCys) were studied as possible interferents. (nel.edu)
