Case

Corn seeds are mainly composed of embryo and endosperm, which account for 10% and 90% of dry weight, respectively. Therefore, the normal development of endosperm is a key factor in determining the yield and quality of corn. The corn seeds are large in size, difficult to grind, and the sample is wasted seriously. Then the research group of corn endosperm development and genetic improvement of the Institute of Plant Physiology and Ecology, Chinese Academy of Sciences purchased the Shanghai Jingxin automatic sample tissue grinder. The Shanghai Jingxin automatic tissue rapid grinder is a Grinding in a closed EP tube successfully solves the problem of time-consuming and laborious manual grinding and waste of samples by teachers, and further analyzes the gene e­xpression regulation network of maize endosperm development and studies the modification mechanism of high-quality protein maize (QPM) endosperm. , gene cloning and functional study of important mutants of maize grains.  

      LAWSON (Luoshan China) automatic sample rapid grinder processing and manual liquid nitrogen grinding processing to extract FT DNA, RNA in concentration and purity There was no significant difference (P>0.05 for paired test). However, manual grinding has a large sample loss rate. For samples with low DNA extraction concentration, the automatic grinder can achieve 0 sample loss, which 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 the automatic sample rapid grinder of LAWSON (Luoshan China), so the automatic grinder has great advantages for DNA extraction work compared to manual grinding.

      LAWSON (Luoshang China) is currently the only domestic manufacturer of horizontal tissue grinders, vertical tissue grinders, and three-dimensional integrated tissue grinders with Manufacturer of a full range of production lines. He is the inventor of the domestic multi-sample tissue grinder and masters the core technology. At the same time, it also provides OEM and OEM processing services to many foreign brands and domestic enterprises.
