How to improve the accuracy of COVID-19 nucleic acid testing?

With the rebound of the COVID-19 epidemic, the demand for nucleic acid testing has increased sharply. However, the accuracy of nucleic acid testing results has attracted widespread attention. The “missing” situation has caused some clinicians and the public to raise questions about the quality of test kits. doubt. So, what are the factors that may […]

What are the functions of immunomagnetic beads?

In recent years, immunomagnetic beads have attracted more and more attention from scientists, and their applications in the field of biomedicine have become more and more extensive. But in fact, immunomagnetic beads are not new products that have only recently developed. As early as the late 1980s, it has begun to play a huge role […]

Introduction of Magnetic Bead Method of Nucleic Acid Extraction Technology

With the rising popularity of nucleic acid testing for the new coronavirus, nucleic acid testing has become deeply rooted in the hearts of the people and has become the “gold standard” for pathogen detection. Since the new crown epidemic, a large number of sample test results have been required in a short period of time, […]

How to do nucleic acid testing?

Now, due to the spread of the COVID-19 epidemic, we are required to do nucleic acid testing when we travel or travel to other countries or provinces. We need to have a negative nucleic acid test result. Then, what should we do? 1. Before testing: (1) Try to avoid eating 2 hours before the nucleic […]

How to choose a suitable nucleic acid extraction system, and what are the misunderstandings in the selection?

With the rapid development of biotechnology, with the application of PCR technology in various fields, including medical disease detection, agricultural genetic modification detection, and many other applications, high-throughput sample nucleic acid extraction has become extremely urgent, and many companies have launched With the automatic nucleic acid extraction instrument, there are various principles.

What are the nucleic acid purification technologies?

At present, nucleic acid purification technologies widely used in scientific research can be divided into two categories: those that use media and those that do not use media. If media is used, nucleic acid is separated from all other impurities at one time; if media is not used, the first step is to separate the […]

Application of immunomagnetic beads in the field of biomedicine

Immunomagnetic bead technology is a technical method that appeared in the 1980s. Based on immunology, it has penetrated into various fields such as pathology, physiology, pharmacology, microbiology, biochemistry, and molecular genetics. It has become more and more widely used in immunoassays, cell separation, purification of biological macromolecules, and molecular biology. Structure of immunomagnetic beads Magnetic […]

How to perform nucleic acid extraction

The common difficulty in nucleic acid extraction lies in the difficulty of extracting high-quality RNA from some plant tissues, which is related to the rich ingredients in these plant tissues, such as phenolic compounds, polysaccharides, and some unidentified secondary metabolites. In addition, there are tissues that are rich in higher activity. In an intact cell, […]
