There is provided a piston of a cartridge for extracting nucleic acids comprising: a cylindrical upper body having a hollow; a lower body having two ports; a control rod module combined to the other end of the upper body to seal the other end and move up and down along the hollow; and a rotation control module that is combined to the shaft of the lower body to transmit a driving force to the lower body.

Piston of nucleic acid extracting cartridge

There is provided a nucleic acid extraction method using a cartridge comprising: (a) a driving part of a nucleic acid extraction device is connected to a control rod module disposed in an inner space of the upper body of a piston and a rotation control module coupled to the lower body of the piston; (b) driving the rotation control module and the control rod module, sequentially sucking sample and reagents from the plurality of chambers separated from each other into an interior space, and discharging the mixture of the interior space into the chamber of the cartridge; and (c) driving the rotation control module and the control rod module to suck the reagent inside the master mix bead chamber of the cartridge into the interior space of the piston upper body and then discharge the mixed reagent to a nucleic acid amplification module.

Method for extracting nucleic acid using cartridge

The present invention discloses a flow path structure of a cartridge for nucleic acid extraction comprising: a plurality of elongated grooves formed on the surface of the cartridge body; and a shaft hole formed in the center of the body, wherein the plurality of grooves have a starting point formed around the shaft hole and an ending point extending from the starting point toward the outer region of the body.

Channel structure of nucleic acid extracting cartridge

There is provided a cartridge for nucleic acid extraction comprising: a first body having a plurality of chambers in which ports are formed at the bottom; a second body coupled to a lower region of the first body; and a piston disposed rotatably in the centers of the first body and the second body and having a port formed at the bottom thereof; and characterized in that the cartridge comprises a plurality of flow paths formed on the upper region of the second body, one end overlapping the port of the piston and the other end overlapping the port of the first body.
