Abstract

The invention discloses a digital multiple-nucleic-acid detection method on the basis of encoding micro-sphere reactors. The digital multiple-nucleic-acid detection method includes steps of extractingsample nucleic acid; designing primers; labeling the primers; carrying out hybrid capture; generating micro-drop; carrying out amplification reaction; carrying out scanning detection and the like. The digital multiple-nucleic-acid detection method has the advantages that multiple-gene detection merits of hybridization technologies and high-sensitivity quantitative detection merits of digital PCR(polymerase chain reaction) are combined with one another, accordingly, gap in the technical field of multiple-gene quantitative detection can be filled, and the digital multiple-nucleic-acid detection method has profound influence.

Description

technical field [0001] The invention relates to the field of molecular detection, in particular to a digital multiplex nucleic acid detection method based on a coded microsphere reactor. Background technique [0002] The principle of multiplex polymerase chain reaction (Polymerase Chain Reaction, PCR) is to add multiple pairs of specific primers in the reaction system at the same time, and simultaneously amplify the DNA fragments of multiple entries. Simultaneous detection of multiple microorganisms can be achieved based on the fragment size of the product or by molecular hybridization. Since the concept of multiplex PCR was first proposed in 1988, after years of development, multiplex PCR technology has gradually matured. Currently, multiplex PCR detection methods mainly include capillary electrophoresis (or gel electrophoresis), liquid phase chip, and mass spectrometry. Capillary electrophoresis is to separate and detect PCR products according to their different amplified...
