Spin column

Abstract

The spin column of the present invention is used for filtering and extracting biological molecules, such as nucleic acids and proteins. When the spin column is used, it is placed inside a collection tube, which is then placed in a centrifuge slot and the centrifuge is activated. The internal volume of the spin column of the present invention is larger than that of a conventional spin column, allowing it to accommodate a larger amount of specimens. Additionally, the filter membrane positioned inside the spin column of the present invention is smaller than that of conventional spin columns. The amount of washing solution required to wash the biological molecules from the filter membrane is proportional to the size of the filter membrane. Therefore, less washing solution is required in the present invention. Since the spin column of the present invention can accommodate a larger amount of specimen, the number of biomolecules contained in the specimen is also larger. Since less washing solution is required to dissolve and recover the biomolecules from the filter membrane, the concentration of collected biological molecules in the washing solution is higher.
