Embodiment Construction

[0020] Below in conjunction with specific embodiment, the present invention is further elaborated. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. For the experimental methods without specific conditions indicated in the examples, the conventional conditions well known to those skilled in the art, or the conditions suggested by the manufacturer were followed.

[0021] 1. Principle

[0022] After the specific primers and probes of the present invention are combined with the DNA template, Taq DNA polymerase uses deoxynucleotide (dNTP) as a substrate to amplify the mutant gene of the internal reference gene (Internal Reference, IR) and the EGFR gene in vitro. increase. Fluorescent PCR technology is used for detection, and fluorescence is released through hydrolysis of specific probes to monitor the progress of PCR reaction and determine the mutation of EGFR gene.

Abstract

The invention discloses a primer, probe and reagent kit for detecting mutation of 2312nd-2313rd sites of an EGFR (epidermal growth factor receptor) gene. The primer is as shown in SEQID No.1-SEQ ID No.2, and the probe is as shown in SEQID No.3. Real-time fluorescence PCR is performed through the reagent kit disclosed by the invention, so that the mutation of an ACCCCA basic group inserted in the 2312nd-2313rd sites of an EGFR gene can be detected.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a primer, a probe and a related kit for detecting EGFR gene mutation. Background technique [0002] The incidence of malignant tumors in China has been increasing year by year in recent years, with more than 1.7 million new patients each year. Lung cancer is one of the most common malignant tumors in the world, and 80%-85% of them are non-small cell lung cancer (NSCLC). In my country, lung cancer has become the first cause of death of malignant tumors, and the 5-year survival rate is about 15%. With the development of tumor molecular biology, targeted therapy has attracted much attention. Selecting appropriate patients for targeted therapy is the key to its success. Epidermal growth factor receptor (EGFR) is an important target of tumor therapy at present. point. [0003] The EGFR gene is located on the short arm of human chromosome 7 (7p12), which is about 118kb long and consists...
