METHOD OF COMPLEX ASSESSMENT OF PRODUCT CONTENT OF OXIDATIVE MODIFICATION OF PROTEINS IN TISSUES AND BIOLOGICAL FLUIDS Russian patent published in 2014 - IPC G01N33/52 

FIELD: biotechnology.

SUBSTANCE: invention is intended for more complete assessment of the oxidative modification of proteins (OMP) and analysis of the ratio of the aldehyde dinitrophenylhydrazones (ADNPH) and ketone-dinitrophenylhydrazones (KDNPH) of the basic and neutral character in plasma and blood cells as well as in animal tissues to determine the degree of manifestation and the stage of oxidative stress. The method is based on the fact that the OMP spectrum is divided into individual geometric shapes that represent rectangular trapeze. Area under the curve of the spectrum of oxidative modification of proteins consists of areas under the curve of ADNPH and KDNPH of the basic and neutral character and is determined by the formula.

EFFECT: method enables not only to estimate the total value of OMP, to determine the value of ADNPH and KDNPH of the basic and neutral character, but also to compare primary and secondary markers of OMP and thereby to reveal the path of violating the native conformation of proteins.
