Compare manual nucleic acid extraction with this nucleic acid extractor

1. Manual method to extract nucleic acid: time-consuming, cumbersome, low nucleic acid extraction efficiency, and easily lead to false negatives and cross infection

2. acid purification system Transgenic Crop Research Automated Nucleic Acid Extractor: to achieve a cross-infection and sterile operation process. The nucleic acid extractor greatly reduces the labor intensity of the operators, reduces the errors and infections in the human operation process, enhances the safety and effectiveness of the biological preparation process, and speeds up the process of nucleic acid extraction.

Automated Nucleic Acid Extractor:

1. Nucleic acid extraction (separation and purification of nucleic acid) mainly refers to the separation of nucleic acid from proteins, polysaccharides, fats and other biological macromolecular substances, but when nucleic acid is separated, the integrity of the primary structure of nucleic acid molecules should be ensured and other molecules should be excluded Pollution.

2. Nucleic acid extraction methods generally include several main steps such as cell cleavage, enzyme treatment, nuclear acid and other biological macromolecules, and nucleic acid purification, and each step can be combined with multiple unique methods or a single method.

3. First, the process of lysing cells through physics, chemistry or enzymatic hydrolysis, releasing the nucleic acid, and removing the protein combined with the nucleic acid, as well as the process of biomolecules such as polysaccharides and fats.

4. On this basis, the nucleic acid is precipitated, and impurities such as salts and organic reagents are removed to obtain purified nucleic acid. This process usually uses a centrifugal clarification method, and the operation takes time and effort.

5. In recent years, the magnetic bead separation technology has emerged, which uses magnetic beads to have a strong affinity for nucleic acid under certain conditions and to adsorb nucleic acid. When the conditions change, the magnetic beads can be separated from the nucleic acid that it has adsorbed, and a purified nucleic acid can be obtained. This method is simple, efficient, easy to operate, and is currently the main method for nucleic acid extraction.
