Abstract

The invention discloses a kit for detecting individual oxidation resistance genetic predisposition, comprising: a specific primer pair for simultaneous detection of No.rs769214 SNP locus on catalase gene (CAT), No.rs4673 SNP locus on NADPH phytol gene (CYBA), No.rs1799983 SNP locus on endodermis NOS gene (NOS3), No.rs1799895 SNP locus on ectoenzyme peroxide dismutase gene (SOD3), and No.rs662 locus on paraoxonase-1 gene (PON1); a specific fluorescent probe pair; an ordinary component for fluorescent quantitative PCR detection, etc. The kit of the invention estimates individual oxidation resistance genetic predisposition by simultaneous detecting mononucleotide polymorphism locus genes of CAT, CYBA, NOS3, SOD3, PON1 closely related to the oxidation resistance ability.

Description

technical field [0001] The present invention relates to the fields of molecular biology and medicine, and more specifically, the present invention relates to a kit for detecting the genetic susceptibility of an individual to antioxidant. Single nucleotides of prototypic coenzyme phytol gene (CYBA), endothelial nitric oxide synthase gene (NOS3), extracellular superoxide dismutase gene (SOD3), paraoxonase 1 gene (PON1) Polymorphic locus genotypes to assess individual genetic susceptibility to antioxidants. Background technique [0002] There is a very important balance system in the human body: oxidation-reduction system. This system regulates the production and metabolism of oxygen free radicals in the body, maintains the proper oxidation capacity and scavenging ability of oxygen free radicals in the body, and thus ensures the progress of life activities. The imbalance of oxidation-reduction system and the accumulation of excessive oxygen free radicals will cause a series o...
