Patent ID: 7429470

Claim:
A method of purifying nucleic acids from cells or viruses comprising: injecting a solution containing cells or viruses to a capillary-shaped container containing magnetic beads, wherein the container has a diameter ranging from 1 mm to 5 mm and a ratio of diameter to length ranging from 1:2 to 1:50, and wherein the size of the magnetic beads is from 50 nm to about 50 μm; vibrating the magnetic beads; irradiating a laser beam onto the magnetic beads to disrupt the cells or viruses and binding proteins and cell debris in the resulting cell or virus lysate to the magnetic beads; fixing the magnetic beads, to which the proteins and cell debris are bound, to a wall of the capillary-shaped container by means of a magnetic force generator; and obtaining a nucleic acid-containing solution without the magnetic beads.
