METHOD OF DETERMINING PEROXIDASE ACTIVITY AND SUBSTRATE MIXTURE FOR DETERMINATION OF PEROXIADSE ACTIVITY Russian patent published in 2014 - IPC C12Q1/28 C12N9/02 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to biotechnology and can be applied in creation of analytic methods with application of peroxidases. Method includes preparation of substrate mixture, introduction of peroxidases in substrate mixture with the following registration of intensity of formed luminescence. Substrate mixture includes the following components, given in final concentrations: buffer solution 10-125 mM, luminol 0.05-8 mM, hydrogen peroxide 0.05-8 mM, 4-aminopyridines 0.1-10 mM, N-carboxyphenothiazine, or N-(carboxymethyl)phenothiazine, or N-(2-carboxyethyl)phenothiazine 0.1-10 mM. And pH of buffer solution constitutes 7.9-9.0.

EFFECT: invention ensures obtaining of high intensity of chemiluminescence and, accordingly, high sensitivity of peroxidase activity determination.
