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.

Beer pasteurizer technology
Water bath type pasteurization machine manufacturers come
The production of pasteurization comes from Pasteur's efforts to solve the problem of beer acidification. At the time, the French wine industry faced a headache: the beer would become sour after it was brewed, and it was impossible to drink at all. And this acidification phenomenon often occurs. Pasteur was invited to study this issue. After a long period of observation, he found that the main culprit in making beer sour was Lactobacillus. Nutritious beer is a paradise for the growth of lactobacilli. A simple boil method can kill the lactobacillus, but the beer is burned out. Pasteur tried to use different temperatures to kill the lactobacilli without destroying the beer itself. After zui, Pasteur's research results are: heating the beer at a temperature of 50 to 60 degrees Celsius for half an hour, it can kill the lactobacilli and spores in the beer without boiling. This method saved the French wine industry. This sterilization method is also called "pasteurization".
The water bath type pasteurization machine manufacturer is in a certain temperature range, the lower the temperature, the slower the bacteria breed; the higher the temperature, the faster the reproduction. But if the temperature is too high, the bacteria will die. Different bacteria have different growth temperatures and heat and cold resistance. Pasteurization is actually the use of pathogens that are not very heat-resistant. They are treated with appropriate temperature and holding time to kill them all. However, after pasteurization, a small number of harmless or beneficial, heat-resistant bacteria or bacterial spores are retained.
Technical characteristics of water bath type pasteurizer manufacturers:
1. The equipment is made of stainless steel SUS304/2B material except for the standard parts such as motor and bearing, which fully meets the requirements of export food hygiene.
This machine series is suitable for the sterilization of vegetable killing tables, dehydrated vegetables, pickled vegetables, low-temperature meat products, dairy products and other foods. Sterilization temperature and speed can be set according to process requirements.
2. The machine adopts SUS304 stainless steel mesh belt. The mesh belt has the characteristics of high strength, small flexibility, non-deformation and easy maintenance. The whole machine runs in balance and low noise, which greatly improves the working efficiency.
3. The heating source of the machine is steam heating, with automatic control steam inlet device, and Zui greatly reduces energy waste.
4. The transmission system of the machine adopts the speed reduction motor to make the conveying speed of the conveyor belt adjustable, and the sterilization process has “arbitraryâ€.
