High-throughput single nucleotide polymorphism detecting method based on magnetic nano-particles and universal label technique

InactiveCN101205560ALow costNo additional typing stepsMicrobiological testing/measurementMulti siteHigh flux
The invention discloses a multi-sample multi-site typing method against single nucleotide polymorphisms (SNP) in a genome by using magnetic nano particles as carriers and combining with the technology of universal label probe. The invention is characterized in that: a labeled PCR product is directly fixed on the magnetic nano particles through covalent unions between labels, or a labeled primer is fixed on the magnetic nano particles to directly execute solid-phase PCR amplification, thereby forming magnetic nano particles-DNA complex (MNP-ssDNA). Then, the MNPs-ssDNA is hybridized with a detecting probe of corresponding site and a labeled universal label probe, thereby achieving multi-sample multi-site high flux SNP detection. The advantages of the invention are that: only a pair of labeled probes are required by using the universal label technology to achieve the multi-site typing, and the typing cost is greatly reduced; meanwhile, the invention overcomes the defects of high cost, time consuming, taking trouble, etc. caused by purifying and concentrating a target sequence waiting for detecting in the prior art by using the advantages that the magnetic nano particles are easily separated, etc. Therefore, the method has the advantages of typing mass samples simply, efficiently and accurately.
