As autumn and winter approach, there are signs of a resurgence of the epidemic in many provinces. According to the epidemic prevention and control dynamics of the National Health Commission, as of 24:00 on October 31, 92 new confirmed cases were reported across the country, including 59 local cases. In the race against the virus, improving the efficiency of nucleic acid testing is of vital importance.
Recently, the Medical Administration Bureau also issued the "Notice on Further Strengthening the Current Nucleic Acid Testing Services for the Novel Coronavirus", which clearly states that nucleic acid testing institutions should provide 24-hour nucleic acid testing services to the public and strive to report the results within six hours.
Baotaiyi Biotechnology has always actively responded to national policies, contributed to epidemic prevention and control, and devoted itself to the research and development of scientific instruments such as molecular diagnostics. The 32-channel fully automatic nucleic acid extraction instrument innovatively developed by it is reported in a timely manner! With the nucleic acid extraction reagent (magnetic bead method) - Swab Quick Extraction version from Baorui Biology, the automated equipment only takes 8.5 minutes to extract swab samples! Effectively accelerate nucleic acid testing and facilitate rapid COVID-19 testing.
The Baorui Biological nucleic Acid Extraction Reagent (magnetic Bead Method) - Swab quick extraction version features high efficiency, time-saving, stability and sensitivity. The purified nucleic acid can be directly used for downstream testing. With the 32-channel fully automatic nucleic acid extractor from Baotaiyi, the process of extracting swab samples only takes 8.5 minutes!
Experimental data
1. Dilute the RNA pseudovirus swab solution samples with non-inactivated sample preservation solution to concentrations of 10⁶copies/ml, 10⁴copies/mL, 10³copies/mL and 10²copies/mL respectively as the samples to be tested. 200 μ l of nucleic acid samples were extracted using the Baorui Biological nucleic acid extraction reagent (magnetic bead method) - swab quick extraction plate.At Baotai YiOn the BTE-32 flux extractorEach extractionSix parallel samples.
