High-performance bio-tube for purifying DNA and method thereof

摘要

A high-performance bio-tube for purifying DNA and a method thereof are provided. The high-performance bio-tube is provided with bio-particles immobilized therein. The bio-particles have particle sizes not more than 100 mum and is capable of binding DNA. A biological sample is added in the bio-tube and then a lysis buffer is added to form an admixture of the biological sample and the lysis buffer for lysing the cells to release DNAs. The admixture is maintained in the bio-tube in a period of time sufficiently to make the released DNAs binding to the bio-particles immobilized in the bio-tube. The remaining admixture in the bio-tube is directly discarded. Then, eluting DNAs bound to the bio-particles by feeding an elution solution in the bio-tube.
