Problems solved by technology
Single-probe real-time quantitative PCR, because each probe is designed for a specific target site, with high specificity, each probe can only detect one target sequence, if multiple target sequences need to be detected, Multiple probes need to be added. Due to the limitation of the absorption wavelength of the fluorescent label of the probe, the types of gene sequence detection are restricted.

technical field [0001] The invention relates to a high-risk human papilloma virustyping detection method and kit, which belong to the field of biotechnology. Background technique [0002] Human papillomavirus (Human Papillomavirus, HPV) belongs to the papillomaviridae family, is a small molecule, non-encapsulated, circular double-stranded DNAvirus, the genome length is about 8000 base pairs (bp), divided into 3 There are three functional regions, namely early transcribed region (E region), late transcribed region (L region) and non-transcribed region (long control region, LCR). HPV infects humans through direct or indirect contact with contaminated objects or through sexual transmission. The virus is not only host-specific, but also tissue-specific. It can only infect human skin and mucosal epithelial cells, and can cause squamous epithelial proliferation of human skin and mucous membranes. More than 130 kinds of papillae that cause human skin have been isolated so far. ...
