Optical sorting method

摘要

A method for increasing the concentration of a nucleic acid molecule comprising the steps of: (a) forming aqueous microcapsules from a water-in-oil emulsion, wherein a plurality of microcapsules include a nucleic acid molecule, a bead capable of being linked to the nucleic acid molecule and an aqueous solution comprising components necessary to perform nucleic acid amplification; (b) amplifying the nucleic acid molecule in the microcapsules to form amplified product copies of the nucleic acid molecule; and (c) capturing the amplified product copies to the bead in the microcapsules; thereby increasing the concentration of the nucleic acid molecule.
