Abstract

The invention relates to the field of biological equipment manufacturing engineering and discloses a biological sample extraction device and method. The device comprises a nucleic acid storage area, a mobile phase storage area, a chromatographic column, a temperature control component, a DNA collecting area and an RNA collecting area, wherein the nucleic acid storage area and the mobile phase storage area are connected with an inlet of the chromatographic column, an outlet of the chromatographic column is connected with the DNA collecting area through a switch I and connected with the RNA collecting area through a switch II, and the temperature control component wraps the chromatographic column. With the adoption of the device and the method, the manual operation involvement degree is decreased, the automatic operation degree is high, and large-scale nucleic acid substance separation is facilitated.

Description

technical field [0001] The invention relates to the field of biological equipment manufacturing engineering, in particular to a biological sample extraction device. Background technique [0002] The processing and extraction of biological samples is of great significance to biological research. Since the biological activity of biological samples will be affected by various environmental factors and the storage time is short, in order to quickly realize the extraction of biological samples, it is necessary to research and develop a complete set of equipment. In the process of genomics research, DNA and RNA are widely used biological materials, and the separation of nucleic acid substances to obtain DNA and RNA has important research significance. In the prior art, molecular kits are usually used to separate nucleic acid substances. This method needs to rely on manual operation, has poor repeatability, and is slow, which is not conducive to large-scale industrial separation ...
