Embodiment Construction

[0020] 1. DNA extraction: Use the phenol-chloroform-isoamyl alcohol method to extract DNA from blood samples, hair with hair follicles, oral mucosal scrapings or saliva samples.

[0021] 2. Design of specific primers and PCR amplification of specific bands: use Primer 5.0 software to design upstream primer 3253F and downstream primer 3253R according to the human mitochondrial gene sequence (NC_012920.1) before and after 3253; use the above primers to contain the specificity of 3253 The band is amplified.

[0022] 3. Specific enzyme digestion and electrophoresis identification: the specific restriction endonuclease BstEII is used to digest the above-mentioned specific band, and the digested product is subjected to agarose gel electrophoresis to identify whether 3253T>C occurs mutation.

[0023] Specific steps are as follows:

[0024] 1. Collect specimens: detect mitochondrial tRNA as above Leu(UUR) In the gene T3253C mutation method, the whole genome DNA can be quickly extra...

Abstract

The invention discloses a method and a kit for mutation detection of a mitochondrion tRNA<Leu(UUR)>3253T>C. The method includes DNA (deoxyribonucleic acid) extraction, specific primer design, specific band PCR (polymerase chain reaction) amplification, specific restriction enzyme BstEII digestion, agarose gel electrophoresis and the like. Results can be obtained within a few hours, and one enzyme is only capable of identifying one specific deoxyribonucleotide sequence, so that accuracy of the results is realized. The invention further provides a kit for mutation detection of the mitochondrion tRNA<Leu(UUR)>3253T>C related to primary hypertension. The method and the kit for mutation detection of the mitochondrion tRNA<Leu(UUR)>3253T>C have the advantages of low requirements on instruments for detection, low cost of required reagents, simplicity and easiness in operation, stability of the method, high specificity and the like.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a method for detecting mitochondrial tRNALeu (UUR) 3253T>C mutation for non-therapeutic and non-diagnostic purposes. Background technique [0002] Cardiovascular disease is the leading cause of death in the world. According to the statistics of the World Health Organization, about 17.3 million people died of cardiovascular disease in 2008. By 2030, almost 23.3 million people will die of cardiovascular disease. Hypertension is number one risk factor for cardiovascular disease. High blood pressure affects more than one-third of adults worldwide, or about 1 billion people, and causes more than 9 million deaths worldwide each year, half of whom die from heart disease and stroke. High blood pressure can also cause kidney failure, blindness, Broken blood vessels and brain damage. According to the cause of hypertension, hypertension can be divided into primary hypertension and...
