A Novel Express Method to Determine Activity of Antitumor Enzyme L-Lysine-α-Oxidase of Trichoderma Harzianum Rifai F-180
Bulletin of experimental biology and medicine(2020)
摘要
A novel express method is developed to determine activity of antitumor enzyme L-lysine-α-oxidase obtained by culturing Trichoderma harzianum Rifai F-180 fungus. The carcinogenic reagent ortho-dianisidine-hydrochloride was replaced in the reaction medium with environmentally friendly reagents of the chromogenic mixture that included tetramethylbenzidine. This method improved precision and sensitivity of ELISA by 10 and 40 times, respectively. In addition, it could detect activity of L-lysine-α-oxidase not only in the producer strains with a pronounced activity of this enzyme, but also in the strains where this activity has not been previously determined.
