Seed DNA Extractor, also known as high-throughput tissue grinder, is an instrument dedicated to sample grinding. In recent years, the instrument has become more and more widely used in modern agricultural research because of the progress of laboratory research. The increasing speed of manual milling has been unable to meet the needs of scientific research, and seed DNA extraction instrument can be used as a good alternative to solve the problem of seed grinding. The use of a seed DNA extraction instrument to grind and crush the seeds of cash crops can effectively improve the efficiency and effectiveness of seed milling, and provide important support for the further extraction of nucleic acids/proteins for seed inspection and analysis.
Application of seed DNA extraction instrument to carry out rice wheat seed grinding, the materials and utensils needed, mainly samples: rice, wheat seeds; instrument: seed DNA extractor; and consumables: centrifuge tubes, grinding beads, etc., grinding process is very simple Only need to go through a simple 4 steps to get the required crushed samples. The first step is to put some rice and wheat seeds into the centrifuge tube; the second step is to add the grinding beads to the centrifuge tube; the third step is to place the sample tube into the adapter; the fourth step is to The adapter is placed in the seed DNA extraction instrument, setting the parameters, starting the instrument grinding, and then the comminuted sample can be obtained, which is not very simple and efficient.
Although the process of grinding rice seeds using a seed DNA extraction instrument is very simple, there are still two areas that need special attention during the operation to improve the grinding effect. The first consideration is the centrifugation tube and beads. It needs to be fully cleaned and dried. If RNA is to be extracted, the grinding tank and grinding beads must be used to ensure the enzyme is inactivated. The second consideration is that the amount of sample to be polished in each centrifuge tube generally follows the principle that the sample volume should not exceed the volume of the centrifuge tube. One-third. These two operators must pay attention when operating.
