Problems solved by technology

That is, during PCR amplification, the extension of the primer starts from its 3' end, and the extension requires that the bases at the 3' end of the primer must be completely paired with the template, only in this way can the primer be extended and the amplification can proceed If the 3' end of the primer cannot be paired with the template, the extension of the primer will be blocked and the corresponding amplification product will not be obtained.

Description

Technical field [0001] The invention belongs to the field of molecular biology gene detection, and relates to a RET fusion gene ARMS fluorescent quantitative PCR typing detection kit, and specifically relates to 7 most common KIF5B-RET fusion gene variants and 1 newly discovered RET fusion genotype ARMS-qPCR The detection kit is suitable for the detection of RET fusion gene mutations in lung adenocarcinoma. Background technique [0002] Lung cancer is the tumor with the highest mortality rate in the world, and its mortality rate is also the first among tumors, mainly including small cell lung cancer (SCLC) and non-small cell lung cancer (non-small cell lung cancer, NSCLC). NSCLC includes squamous cell carcinoma. , Adenocarcinoma, adenosquamous carcinoma, large cell carcinoma, carcinoid, etc. In my country, the mortality rate of lung cancer has ranked first among tumor mortality rates. Among them, the incidence rate of NSCLC accounts for 80% of all lung cancer incidence rates, an...
