Abstract

The invention belongs to the field of biotechnology, particularly relates to the field of virus detection, and more particularly relates to a PCR primer group, probe and kit and detection method for detecting human immunodeficiency virus-1 2-LTR DNA. The detection primer group provided by the invention comprises nucleotide sequences shown as SEQ ID NO: 1-6; and the detection probe comprises nucleotide sequences shown as SEQ ID NO: 7-8. The detection primer group provided by the invention is different from the conventional real-time fluorescence quantitative PCR; through introduction of 3 pairs of real-time fluorescent quantitative PCR primers, that is, 6 primers, adoption of multiple cycles, and increase of the primer annealing temperature, the PCR detection method for detecting the HIV-1 2-LTR DNA, provided by the invention, achieves extremely high sensitivity and specificity, and the minimum detection limit can reach 2 copies per million cells in each PCR; and moreover, when a quantitative cell reaction system is further added in the PCR reaction, the HIV-1 2-LTR DNA and the number of cells can be quantified at the same time in the same PCR reaction (in the conventional method, the cell count is additionally required).

Description

technical field [0001] The invention belongs to the field of biotechnology, specifically relates to the field of virus detection, and more specifically relates to a PCR primer set, a probe, a kit thereof and a detection method for detecting human immunodeficiency virus type 1 2-LTR DNA. Background technique [0002] Human Immunodeficiency Virus (HIV) is a lentivirus that infects cells of the human immune system and is a type of retrovirus. Human immunodeficiency virus was first identified in the United States in 1983. The virus destroys the immune ability of the human body, causing the immune system to lose its resistance, which leads to the survival of various diseases and cancers in the human body, and eventually leads to AIDS. According to incomplete statistics, it is estimated that 35.9 to 44.3 million people in the world live with HIV, of which 4.3 to 6.4 million are new infections, and 2.8 to 3.5 million die from AIDS. [0003] In recent years, combined antiretrovira...
