Magnetic beads are the main tool of new nucleic acid extraction technology. Magnetic beads have the characteristics of monodispersity, high specific surface area, good dispersibility and resuspension, faster magnetic response, better water solubility, and more active functional groups. They can form a “quasi-homogeneous” reaction system. It can combine, react and separate with the target fragment […]
Magnetic beads are important equipment used in biological immunology. They have super paramagnetism and can quickly accumulate in a magnetic field. After leaving the magnetic field, they can contribute to the uniform dispersion of magnetic separation. By coating the surface of the magnetic beads with specificity Antibodies, receptors, etc., are used to separate and purify […]
The nucleic acid extraction system is a biomedical system designed for automatic magnetic bead method nucleic acid extraction. You only need to add the sample to be extracted to the matching kit, put the kit into the extraction system, run the edited program that comes with the system, and complete a round of sample nucleic […]
Since the birth of Watson and Crick’s DNA double helix model, biology has entered a new era. In the biological world, DNA is required, and the central rule is required. The extraction of DNA has become the field of biomedicine and even agriculture, forestry, animal husbandry and fishery. The foundation of scientific research in all […]
Magnetic beads play an important role in nucleic acid extraction. The specific process is to first lyse the cells, then combine nucleic acids with magnetic beads through the binding solution, and use washing solution to wash away residual protein and salt ions, and then combine nucleic acids and magnetic beads. Separate. Seeing that the process […]
Nucleic Acid Extraction System (Nucleic Acid Extraction System) is an instrument that uses matching nucleic acid extraction reagents to automatically complete sample nucleic acid extraction. It is widely used in various fields such as the Center for Disease Control, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbiological testing, food safety testing, animal husbandry […]
We know that the rapid detection and sampling of human neocorona nucleic acid is mainly through nasopharyngeal swabs or oropharyngeal swabs. So how to do rapid detection of new crown nucleic acid for frozen food? In fact, the rapid detection of COVID-19 for food is similar to the rapid detection of human COVID-19. Next, let’s […]
With the continuous development and improvement of extraction technology, magnetic bead extraction technology continues to rise in China. As the core material for extraction, magnetic beads are constantly being known. Magnetic beads are formed by covering a core of ferroferric oxide with a certain tissue, which can be adsorbed by magnets and at the same […]
There are many types of nucleic acid extraction kits，such as bacterial genomic DNA extraction kit ,whole blood genomic DNA nucleic acid extraction kit and etc. Today, we will mainly introduce the principle, use method and specific steps of the magnetic bead method nucleic acid extraction kit. What is nucleic acid Nucleic acids are widely present in […]
The nucleic acid detection material is the nucleic acid of the virus. Nucleic acid testing is to find out whether there are nucleic acids of foreign viruses in the respiratory specimens, blood or feces of patients to determine whether they are infected by the new coronavirus. Therefore, once the test is “positive” for nucleic acid, […]
