Abstract

The invention relates to a multiplex detection primer probe for ESR1 gene mutation and a kit thereof. The multiplex detection primer probe comprises an upstream primer, a downstream primer, a wild type probe, a mutant type probe MP-Y537C for detecting ESR1 gene No.10 exon Y537C mutation, a mutant type probe MP-Y537N for detecting ESR1 gene No.10 exon Y537N mutation, and a mutant type probe MP-Y537S for detecting ESR1 gene No.10 exon Y537S mutation. And the mutant probe MP-D538G is used for detecting the mutation of the No.10 exon D538G of the ESR1 gene. The ESR1 gene mutation multiple detection primer probe and the kit thereof are rapid and efficient, the preparation of a standard substance is simple, the specificity and sensitivity of a detection system are high, the utilization rate of free DNA is high, and the accuracy is high.

Description

technical field [0001] The invention relates to an ESR1 gene mutation detection product, which belongs to the field of biotechnology. Background technique [0002] ESR1 (Estrogen Receptor1) gene encodes the human estrogen receptor alpha protein (Estrogen receptor alpha, ESRα), which, after combining with estrogen, activates a series of cycle reactions in cells to promote cell growth and proliferation. Activating mutations of the ESR1 gene are closely related to the occurrence and development of breast cancer. Among them, the most common mutation types of ESR1 gene are Y537S, Y537C, Y537N and D538G. These mutations alter the conformation of ESRα, allowing it to exhibit a persistently active state in the absence of estrogen binding. [0003] Breast cancer is one of the most common gynecological tumors. More than 70% of primary breast cancers are estrogen receptor (ER) positive, and many breast cancers initially respond to endocrine therapy. Although the development of new ...
