• Environmental and breathing zone samples were analyzed for 3,3'- dichlorobenzidine (91941) (DCB) and ortho-dianisidine (119904) (ODA) at Harshaw/Filtrol (SIC-2865), Louisville, Kentucky in August, 1984. (cdc.gov)
  • Amylase was assayed measuring the maltose produced by the breakdown of starch and peroxidase with ortho dianisidine. (usp.br)
  • mM phosphate buffer 6 pH.0, containing 0.167 mg/ml O-dianisidine dihydrochloride and 0.0005% hydrogen peroxide and assayed spectrophotometrically for MPO activity determination at 450 nm (Multiskan GO Microplate Spectrophotometer, Thermo Fischer Scientific, Vantaa, Finland). (bassresearch.com)
  • Benzidine condensed with acetophenone and benzophenone to form the corresponding di-anils, o-tolidine reacted similarly with acetophenone but not with benzophenone, and o-dianisidine did not react with either acetophenone or benzophenone. (gla.ac.uk)
  • Benzoin reacted with benzidine, o-tolidine and o-dianisidine to form didesyl-derivatives, which in contrast to the di-anils, were extremely resistant to hydrolysis. (gla.ac.uk)
  • ce {Peroxidase}}]{ROH}+R'OH}}} Where the ROOR' can be hydrogen peroxide, and the electron donor be o-dianisidine. (wikipedia.org)
  • o-Dianisidine is also used in assaying activity of peroxidase in lab. (wikipedia.org)
  • o-Dianisidine is a precursor to some azo dyes by formation of the bis(diazonium) derivative, which is coupled to diverse aromatic compounds. (wikipedia.org)
  • Some commercial dyes derived from o-dianisidine include C. I. Direct Blue 1, 15, 22, 84, and 98. (wikipedia.org)
  • Myeloperoxidase was solubilized with hexadecyltrimethylammonium bromide and myeloperoxidase activity was measured with a dianisidine-H2O2 assay. (nih.gov)
  • The working reagent solution was prepared immediately before use by mixing 1 volume of substrate solution (o-dianisidine dihydrochloride: 7.8 mM, Triton X-100: 1% v/v) with 4 volumes of sodium acetate buffer solution (100 mM, pH adjusted to 4.6). (medscape.com)
  • A complete of 10 μL from the retrieved supernatants was put into a 96-well dish accompanied by the addition of 100 mmol/L potassium phosphate buffer including 1.5 mol/L H2O2 and 167 μg/mL o-dianisidine dihydrochloride. (healthy-nutrition-plan.com)
  • 2014). [ 12 ] Briefly, the procedure is based on the CP-mediated oxidation of o-dianisidine, a chromogenic substrate forming a yellow-brown reaction product that absorbs at 500 nm. (medscape.com)
  • [ 11 ] The following parameters were used to provide the results in international units per liter (IU/L), parameters we used were as follows: molar absorption coefficient of o-dianisidine oxidation product at 37°C (ε500 nm) = 4.83x10 [ 3 ] L/mol/cm, optical path length = 1 cm, dilution factor = 2 1, and change in time = 100 s. (medscape.com)
  • Molar consumption of NADPH and O(2) and molar H(2)O(2) production (o-dianisidine oxidation) revealed that Group 1 compounds mostly increased, Group 2 had no effect, and Group 3 decreased the H(2)O(2)/O(2) and H(2)O(2)/NADPH ratios. (nih.gov)
  • In fact, it has been established that the common peroxidatic electron donor o-dianisidine does inhibit the catalase activity of KatG from Escherichia coli at pH 7.5. (auburn.edu)
