Abstract

The invention relates to a primer, a kit and a method for detecting the transcription level of purine nucleoside phosphatase PNP gene in rhesus monkey liver by RT-qPCR, and belongs to the field of molecular biology technology. The method of the present invention uses the cDNA synthesized by reverse transcription of the total RNA extracted from the fresh liver tissue of rhesus monkey as a template, and uses the PCR primer combination to perform real-time fluorescent quantitative PCR amplification to obtain PNP Gene fragments and reference genes GAPDH The Ct value, dissolution peak, and amplification efficiency of the fragments were normalized by routine processing. PNP The ΔΔC(t) value of the gene fold expression, thus obtaining PNP Relative expression values ​​of gene transcript levels. The invention provides an effective way for studying the PNP function of macaques and the influence of related drugs on it. At the same time, the invention is suitable for real-time quantitative PCR detection, and has simple operation, high repeatability, low detection cost, high sensitivity and strong specificity. Easy to promote applications.

Description

technical field [0001] The invention belongs to the technical field of molecular biology, and relates to a detection method, in particular to a method for detecting the transcription level of purine nucleoside phosphatase PNP gene in rhesus monkey liver by real-time fluorescence quantitative RT-qPCR method. Background technique [0002] Purine nucleoside phosphorylase (PNP or PNPase for short) is an enzyme involved in purine metabolism. The enzyme catalyzes the conversion of inosine, xanthine, and guanosine into hypoxanthine, xanthine, and guanine. Inosine is the starting material for the synthesis of uric acid in the body. It is hydrolyzed by PNP enzyme to form hypoxanthine, which is then oxidized by xanthine oxidase (XO) to form xanthine and then uric acid. [0003] In recent years, with the improvement of people's living standards, dietary structure and living habits have changed, and the prevalence of hyperuricemia (HUA) has increased year by year. Epidemiological resea...
