It can be happy many times during the year. The flower bud differentiation can be carried out on the basis of stopping the growth of the shoot tips and having certain nutrients. When the shoots sprouted in the same year, the results can be flowered. In order to avoid the leaves caused by excessive drought, the water can be controlled for 3 days, watered for 2 days, and treated repeatedly and intermittently. If you are lazy, you can also pour water for 5-7 days.

Magnetic Bead Nucleic Acid Extraction Reagent

The magnetic bead method nucleic acid extraction kit is a high-tech product that combines biological science and nanomaterial science. It is a major breakthrough in my country's nucleic acid extraction and purification technology. . Magnetic bead method for nucleic acid extraction has incomparable advantages over traditional DNA extraction methods, which are mainly reflected in: 1. It can realize automatic and large-scale operation. At present, there are 96-well nucleic acid automatic extraction instruments, and the extraction time of one sample can be realized. The processing of 96 samples complies with the high-throughput operation requirements of biology, enabling rapid and timely response to infectious disease outbreaks, which makes traditional methods unmatched; â‘¡ The operation is simple and time-consuming, and the entire extraction process has only four steps , most of them can be completed within 36-40 minutes; â‘¢ Safe and non-toxic, no toxic reagents such as benzene and chloroform in traditional methods are used, and the damage to experimental operators is minimized, which fully conforms to modern environmental protection concepts; â‘£ Magnetic beads and nucleic acids The specific binding of the extracted nucleic acid results in high purity and high concentration of the extracted nucleic acid. According to the same principle as the silica membrane spin column, the superparamagnetic silica nano-magnetic beads are prepared after the surface of the superparamagnetic nanoparticles is modified and modified by nanotechnology. The magnetic beads can specifically recognize and efficiently bind to nucleic acid molecules on a microscopic interface. Using the superparamagnetic properties of silica-coated nanomagnetic microspheres, under the action of Chaotropic salts (guanidine hydrochloride, guanidine isothiocyanate, etc.) and an external magnetic field, samples from blood, animal tissues, food, pathogenic microorganisms, etc. The isolated DNA and RNA can be used in clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, molecular biology research and other fields. Magnetic bead nucleic acid extraction can generally be divided into four steps: lysis-binding-washing-elution. Genetic testing will surely become a new symbol of the development of the biological industry. The emergence of high-throughput, automated nucleic acid extraction methods will reduce the labor cost of genetic testing, make large-scale testing a reality, and make it possible for genetic testing to reach ordinary people.
