A kind of dna extraction method

Abstract

The invention belongs to the technical field of genetic engineering, and particularly, relates to a DNA extraction method which comprises an upper shell, a lower shell, a buffer solution storage chamber, a bottom plate, a sliding plug, a transmission shaft and rolling wheels. The buffer solution storage chamber is fixedly connected to the top of the upper shell; the bottom plate is fixedly connected to the bottom of the inner side of the buffer solution storage chamber; the transmission shaft penetrates through the middle of the side wall of one side of the upper shell and is arranged in the middle of the opposite side wall, and the transmission shaft is connected with the side walls through bearings; the rolling wheels are connected to the middle of the transmission shaft in a sleeving mode at intervals, the rolling wheels are eccentrically and fixedly connected to the middle of the transmission shaft, the distances between the center line of the transmission shaft and the center lines of the rolling wheels are equal, and the two rolling wheels are mutually rotationally symmetrical. According to the assembly method of the upper shell and the lower shell, the instrument is more convenient to use, the DNA extraction instrument is simpler and more convenient to carry, and the requirement of extracting sample DNA in various outdoor weather environments can be met.

Description

technical field [0001] The invention belongs to the technical field of genetic engineering, in particular to a DNA extraction method. Background technique [0002] With the development of science and technology, biological gene technology is also changing with each passing day. When studying some rare species or mutant species, NDA extraction and analysis are often carried out to understand their genetic status and study their biological characteristics. In order to understand the root cause of the unique external characteristics of these creatures, DNA extraction is gradually becoming more and more frequent during this process. In addition, many scientific expedition teams and expedition teams also need to analyze some biological samples found in the wild. For DNA extraction, as we all know, there are many things that need to be carried for scientific research in the field. Therefore, the DNA extraction equipment used needs to be portable, easy to carry, reliable and practi...

AI Technical Summary

Problems solved by technology

[0003] The current DNA extraction instruments are relatively bulky, not easy to carry manually, and need to use various laboratory utensils in the process of use, which is even more unfavorable to carry and easy to damage, so the DNA extraction instrument is easy to carry and easy to use It is becoming more and more important for biological research and scientific research
