At the beginning of p>22, novel coronavirus suddenly broke out in Wuhan. China quickly took a series of prevention and control measures, such as closing the city, shutting down households, isolating infected or suspected patients, and cut off the infection route in novel coronavirus. It also carried out nucleic acid testing in COVID-19 to find and treat patients in time, which made the domestic epidemic situation effectively controlled. Nevertheless, the improvement of vaccine research, prevention and control in COVID-19 has not stopped.
According to media reports, Jennifer? The research team led by Dudner proposed a COVID-19 detection method based on CRISPR gene editing technology. Jennifer? Dudner is a professor at the University of California, USA, for which he won the Nobel Prize in Chemistry. The new COVID-19 detection method proposed by his team takes shorter detection time than the previous method, and it only takes 5 minutes to get the detection results, while the previous detection method takes about 1 hour to complete the detection. Ii. introduction of Covid-19 detection method based on CRISPR gene editing technology
Covid-19 detection method based on CRISPR gene editing technology not only takes short time, but also does not need expensive equipment support, and can be directly used in offices, schools, office buildings and other occasions. The principle of the detection method of CRISPR gene editing technology is that after the guide RNA is combined with the RNA sequence of Covid-19, the RNA is cut off and fluorescent particles are released, so that fluorescence can be displayed under the irradiation of laser. The previous COVID-19 detection method needs to increase the amount of RNA in Covid-19 before it can enter the detection process. This method needs high cost and long time, and it also makes COVID-19 detection more complicated. The improved Covid-19 detection method can complete the detection without increasing the number of RNA in Covid-19, and at the same time, it can get the specific number of Covid-19 in the sample. Third, the specific operation of the new Covid-19 test < P > The improved Covid-19 test is essentially an improvement of the detection technology, but there is no difference in the sample collection operation. The sampling operation is to wipe the back wall and tonsils of the mouth with a throat swab until the throat swab is soaked, put it in a test tube and seal it, and then carry out Covid-19 detection.
