An RNA grinding and extraction system

Abstract

The invention belongs to the technical field of RNA extraction, and particularly relates to a RNA grinding and extracting system. The RNA grinding and extracting system adopts RNA grinding equipment which comprises a box, a centrifugal tube, a grinding head, a power module, a clamping fixed module, a heat preservation module, a nitrogen circulating pressure maintaining module, a nitrogen guiding module and a pressing module, wherein a cantilever is arranged on the box; the power module is fixed on the cantilever; the grinding head is connected to the power module; the power module is used fordriving the grinding head to rotate positively and negatively and move upwards and downwards linearly; the clamping fixed module is located on the box and is used for clamping and fixing the centrifugal tube on the box; the heat preservation module is used for heat preservation of the centrifugal tube; the nitrogen circulating pressure maintaining module is used for feeding nitrogen into the box and maintaining the stability of the pressure of nitrogen in the box; and the nitrogen guiding module is communicated with the box and is used for guiding nitrogen into the grinding head. The RNA grinding and extracting system has the beneficial effects that RNA is extracted and ground mechanically, can be fully refined and ground and facilitates extraction of RNA.

Description

technical field [0001] The invention belongs to the technical field of RNA extraction, in particular to an RNA grinding and extraction system. Background technique [0002] RNA in cells can be divided into three categories: messenger RNA, transfer RNA, and ribosomal RNA. Total RNA with high purity and good integrity is a necessary prerequisite for gene cloning, gene expression, and gene function analysis. These three types of RNA All exist in the cytoplasm, so the essence of total RNA extraction from different tissues is to crack cells, release RNA, and remove impurities such as protein and DNA in different ways, and finally obtain high-purity RNA products. [0003] Traditional RNA sample grinding is manual grinding, and glass or ceramic grinding rods are often used to grind samples, but manual grinding will cause sore hands and insufficient grinding. At the same time, manual grinding of samples takes a long time and insufficient grinding, which will cause Affect the recove...
