Abstract

The invention belongs to the technical field of molecular biology, and particularly relates to a method for detecting an ADRB1 gene single nucleotide polymorphic site. The method comprises the following specific steps: 1) design of a specific primer: designing a specific amplification primer, an ARMS specific amplification primer, an interior label amplification primer, a specific probe and an interior label probe according to a proved ADRB1 gene label single nucleotide polymorphic site, wherein the 5' end of the specific probe carries a fluorescent group, and the 3' end of the specific probe carries a fluorescent quenching group; 2) acquiring DNA (Deoxyribonucleic Acid) of a sample genome to be detected; 3) fluorescent quantitative PCR (Polymerase Chain Reaction) amplification: performing a PCR reaction by taking the DNA of a sample to be detected as a template with the specific amplification primer in the step 1), and analyzing a detection result. The method has high sensitivity and high specificity, and is easy and convenient to operate; detection can be finished within 90 minutes, and a result interpretation method is simple, objective and convenient for analysis.

Description

technical field [0001] The invention belongs to the technical field of molecular biology, and in particular relates to a method and a kit for detecting single nucleotide polymorphism sites of ADRB1 gene. Background technique [0002] Cardiovascular diseases such as high blood pressure seriously threaten human health. They are common diseases among middle-aged and elderly people over 50 years old, and have the characteristics of high prevalence, high disability rate and high mortality rate. According to conservative estimates, the number of hypertensive patients in my country exceeds 160 million, and the incidence rate is increasing year by year. Treatment of hypertension and its complications has become the third largest economic burden worldwide. Drugs are the main means of treating hypertension and its complications at present and for a long period of time in the future. [0003] However, due to the physiological state of the patient (such as age, gender, race, obesity, ...
