What Is the Magnetic Pearl Nucleic Acid Extract and What Are Its Advantages? -Prang Medical

  Author:MeCan Medical–ultrasound machine manufacturers

There are many methods for extraction of nucleic acid extraction, such as phenol chlorine pumping method, centrifugal column purification, genetic nucleic acid rapid release technology, RNA rapid extraction kit, and magnetic bead method nucleic acid separation technology. At present, most of the automatic nucleic acid extract in the market is the magnetic bead method. Next, I will introduce to you what is the magnetic pearl nucleic acid extract instrument and what are its advantages?

What is a magnetic pearl nucleic acid extract instrument?

The magnetic bead method nucleic acid extract instrument is based on the magnetic beads, using magnetic beads to adsorb nucleic acid under high salt and low pH, separates the characteristics of separation from nucleic acid under the low salt and high pH value, and then use mobile magnetic beads or transfer liquid to achieve nucleic acids. The entire extraction process.

The principle of extracting nucleic acid by magnetic bead method: Magnetic beads carrying positive charges are easy to adsorb nucleic acids with negative charge, which are mainly used to extract DNA and RNA from human serum or plasma samples (such as detecting HIV or HBV virus genomes from blood samples to prepare sample preparation To. Generally speaking, mix the sample with the buffer and magnetic beads. After combining the nucleic acid with the magnetic beads, after several washing and the capture of the magnetic field, the eluted nucleic acid can detect specific DNA or RNA through PCR or other specific methods. Essence

What are the advantages of magnetic pearl nucleic acid extract?

1. Can achieve automation and high -throughput operations;

2. Simple and fast operation. The entire extraction process is only three steps: cracking -washing -elution, no professional training technicians, and most of them can be completed within 60 minutes;

3. Safe and environmental protection. The entire extraction process does not need to use organic reagents such as phenol, chloroform, safe and non -toxic, green and environmentally friendly, reducing the damage to the operator;

4. High purity, high gain rate;

5. Adopt an intelligent operating system to strictly control the pollution in batch; use disposable plastic extract of the sleeve to avoid pollution inter -batch; at the same time, ensure the stability and repetitiveness of the experimental results, to avoid differences and errors caused by manual operations;

6. You can handle different types of samples at the same time.

The magnetic pearl method nucleic acid extraction instrument produced by Proven Medical Device manufacturers has the configuration of high -throughput fully automatic detection nucleic acid, extraction rate and detection rate, fast detection speed, and at the same time. Control, maintaining nucleic acids, no need to transfer it immediately, which greatly facilitates the work of the operator.

  Author:MeCan Medical–ultrasound machine manufacturersThe nucleic acid extract instrument is a supporting nucleic acid extract reagent from the motion to complete the sample nucleic acid extraction work. In the detection of the new crown, nucleic acid extraction is a very important step. At present, the extraction principle of nucleic acid extract instruments on the market is mainly divided into two types: magnetic bead method and membrane adsorption method, of which magnetic bead method occupies the mainstream market. So, what is the extraction step of the magnetic pearl nucleic acid extract instrument?Step 1: Add samples to the cracking solution.Step 2: In the cracking solution, the rupture cells release the nucleic acid to the cracking solution to transfer the magnetic beads to the cracking solution step 3: Fully mix the nucleic acid to adsorb the specific package on the surface of the magnetic beads.Step 4: Repeat the surface of the magnetic beads to remove impurities such as the unnecessary nucleic acid, protein or salt that are not needed.Step 5: Move the magnetic beads into the eluing solution and mix it fully. The nucleic acid is falling off from the surface of the magnetic bead and dissolved into the elution buffer.The magnetic pearl nucleic acid extract instrument is matched with different types of magnetic pearl nucleic acid extract reagents, and multiple samples are operated at the same time, which automatically separate the extraction and purification DNA/RNA from multiple samples such as blood, cells, tissues, viruses. The instrument uses a special magnetic stick adsorption, transfer, and releases magnetic beads to achieve the transfer of sample/magnetic bead/nucleic acid, avoiding liquid treatment, and increasing the degree of automation.Nucleic acid detection, as an important means of screening of new crown virus screening, is expected to maintain a high position for a period of time at home and abroad. The corresponding nucleic acid extract will be very strong in a considerable period of time. The operation is automated, fast, and simple, which provides a strong guarantee for the detection of new crown nucleic acid.
