Abstract

The invention relates to a quantitative PCR detection method for hepatic tissue HBVcccDNA. The method comprises the following steps: extracting a genome DNA specimen in hepatic tissues; establishing a beta-actin plasmid standard; taking total RNA of adult peripheral blood cells as a template, performing inverse transcription to synthesize cDNA; performing PCR amplification on corresponding cDNA target fragments of human beta-actin genes by taking the cDNA as a template, establishing to form recombinant plasmid by taking pMD18-T as a carrier, performing electrophoresis and sequencing identification, and making a beta-actin standard curve by using fluorescent quantitative PCR. According to the method disclosed by the invention, HBVcccDNA and beta-actin in the hepatic tissues can be subjected to sensitive and specific amplification, quantification of the HBVcccDNA in hepatic cells is realized, and the method can be used for detection and application of HBVcccDNA in the clinical hepatic tissue and hepatic cells.

Description

technical field [0001] The main technical method of the present invention is real-time fluorescence quantitative PCR (Quantitativereal-timePCR, qRT-PCR), the basic principle of this technology is based on three items of molecular hybridization, gene amplification, and photoelectricity, adding fluorescent groups in the PCR reaction system, The process of PCR reaction is monitored in real time with the accumulation of fluorescent signal along with the PCR reaction, and the technology of detecting and analyzing the PCR reaction through analysis software. Background technique [0002] In the 1880s, Miller et al. used DNA electrophoresis and Southern hybridization detection techniques to first confirm that there was an HBV DNA molecule with an electrophoretic band of 2.0 kb in the liver tissue of patients with chronic hepatitis B, and it was confirmed under an electron microscope that it was about 3.2 kb in size. Supercoiled DNA molecule, the first discovery and report of the exi...
