Problems solved by technology

However, the detection cost of the chip method is high, and the open-tube operation has a high rate of false positives. Although the detection sensitivity is relatively high, the requirements for chip detection equipment and instruments have also become a major obstacle to clinical detection, making it difficult to popularize and promote.

Abstract

The invention provides a detection kit. The kit adopts UGT1A1*60(-3279T/G), UGT1A1*93(-3156G/A), UGT1A1*28(-536/7) and UGT1A1*6(211G/A) four loci as the detection objects, and takes molecular beacon probe fluorescent quantitative PCR as the basis to carry out genotyping detection. The kit provided by the invention can detect four loci at one time, greatly saves cost, and provides a reliable method for clinical diagnosis and scientific research of relevant fields.

Description

technical field [0001] The invention relates to a UGT1A1 combined gene site fluorescence detection kit for guiding individualized treatment of irinotecan chemotherapy drugs, which belongs to the technical field of molecular biology detection. Background technique [0002] In recent years, pharmacogenetics / pharmacogenomics has made breakthroughs in the research on the mechanism of action of chemotherapy drugs, and found that the killing effect of chemotherapy drugs on tumor cells is related to the expression of a specific gene (group) and / or polymorphisms were significantly associated. Through the detection of related genes, predicting the efficacy of chemotherapy drugs and selecting appropriate drugs for individualized chemotherapy has become a reasonable choice to improve efficacy and reduce ineffective treatment. [0003] Individualized chemotherapy is based on the characteristics of pharmacogenetics and pharmacogenomics of cancer patients, using specific and optimal chem...
