APPARATUS AND METHOD FOR ISOLATING OR PURIFYING TARGET SUBSTANCE FROM BIOLOGICAL SAMPLE

Document Type and Number:

WIPO Patent Application WO/2018/143557

Kind Code:

A1

Abstract:

The present invention relates to an apparatus and method for efficiently isolating or purifying a target substance from a biological sample by using a sample comprising magnetic particles and an apparatus comprising a magnet. In the apparatus according to the present invention, a transfer unit, together with a rotation motion, moves up and down in a reagent inside a chamber, and thus the magnetic particles and a buffer are sufficiently mixed, so that even when a small amount of elution buffer is used, the mixing of the magnetic particles and the buffer can be attained. In addition, since the reagent inside the chamber is mixed by fast and strong rotation, the process does not proceed while the magnetic particles remain at the corner of the chamber or adhere to a wall portion thereof, with the results that the extraction efficiency of the target substance can be maximized and the efficiency of subsequence PCR analysis can also be improved.
