[0079] Aiming at achieving addressable fixation of nucleic acid fragments containing the SNP site to be tested by indirect means, the present invention proposes the first embodiment: the nucleic acid fragment containing the SNP site to be tested is first fixed on the microsphere, and then the microsphere Fixed on a solid-phase carrier to achieve addressable fixation of nucleic acid fragments containing the SNP site to be tested.

[0080] Further, the step A includes the following steps:

[0081] A1. Use specific primers to perform non-single-molecule amplification on the sample to be tested to obtain a nucleic acid fragment containing the SNP site to be tested;

[0082] A2. Fix the nucleic acid fragment containing the SNP site to be tested on the microsphere, and then fix the microsphere addressably on the solid phase carrier.

[0083] It should be noted:

[0084] The sample to be tested is any form of sample containing nucleic acid, including but not limited to purified DNA, cDNA or R...

Abstract

The invention relates to the technical field of DNA detection, and provides an SNP typing method and a kit. The method comprises the following steps: A, fixing a nucleic acid segment containing a to-be-tested SNP site on a solid-phase carrier in an addressable manner; B, sequencing the nucleic acid segment containing the to-be-tested SNP site fixed on the solid-phase carrier, so as to determine the genetype of the to-be-tested SNP site on the nucleic acid segment, wherein the nucleic acid segment containing the to-be-tested SNP site is the product obtained by non-single molecule amplification. The kit comprises a specific primer pair and a solid-phase carrier, wherein the specific primer pair is used for obtaining the nucleic acid segment containing the to-be-tested SNP site by non-single molecule amplification; the solid-phase carrier is used for fixing the nucleic acid segment containing the to-be-tested SNP site in the addressable manner. By adopting the method and the kit disclosed by the invention, mutual interference between different probes can be avoided, and the flux for detecting the SNP site is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of DNA detection, and more specifically, to a SNP typing method and a kit. Background technique [0002] Single Nucleotide Polymorphism (SNP) refers to changes such as conversion, transversion, insertion, deletion, etc. at a specific nucleotide position in DNA in the genome. At present, there are the following types of SNP typing detection technologies available at home and abroad: high resolution melting curve detection (high resolution melting, HRM), SNP typing based on chip technology, and allele-specific amplification method (Amplification Refractory Mutation System Real Time PCR, ARMS-RT PCR), Taqman fluorescent probe method, mass spectrometry and high performance liquid chromatography, etc. [0003] Among them, the SNP typing method based on chip technology is most commonly used because of its ability to detect multiple SNP sites at the same time and its relatively high throughput. The principle is to fix a ...
