The Human Genome Research Center of Huazhong University of Science and Technology, dedicated to the study of gene cloning and function of human genetic diseases, has established new methods and technologies for genetic diagnosis and treatment of major diseases (cardio-cerebral blood vessels, tumors, blood, nervous system, hepatitis, etc.) . It is also a public scientific research platform for conducting human genetic research.

The center purchased a Shanghai Jingxin Technology Tissuelyser-24 automatic sample rapid grinder to quickly process the experimental samples that the laboratory often contacts, such as the blood vessels of human and animal samples.

There is no significant difference in the concentration and purity of the DNA and RNA extracted from FT after the automatic sample rapid grinder treatment and manual liquid nitrogen grinding treatment of Shanghai Jingxin (pairwise test P>0.05). However, manual grinding has a larger sample loss rate. For samples with low DNA extraction concentration, the automatic grinder can achieve zero sample loss. It has obvious advantages in DNA extraction, and the manual processing process is complicated and easy to cross. Contamination, operation time and other aspects are not as good as Shanghai Jingxin's automatic sample rapid grinder, so the automatic grinder has great advantages for DNA extraction compared to manual grinding.
