Detection of SARS-CoV-2 antigen — detection results of different mutant strains

Since the outbreak of sars-cov-2 pandemic, a variety of variant strains have appeared all over the world. From the discovery of a new coronavirus variant alpha (b.1.1.7) in Britain for the first time in December 2020 to the Delta (b.1.617.2) variant strain that caused many outbreaks in China some time ago, the infectivity caused by virus variation is strengthening, Therefore, the identification of mutant strains has become one of the keys to epidemic prevention and control!

The various recombinant COVID-19 N mutant antigens were collected from WE BALL organisms and detected by our new crown antigen detection (application plan). The detection methods and results are as follows:
The recombinant antigens of different coronal mutations were diluted to different concentrations with lysate
1ng / ml, 0.2ng/ml, 50pg / ml, 25pg / ml and 70ul samples were added. According to the color development of antigens of different N mutants, the detection of test strips was analyzed.

RESULT:

According to the comparative data of this experiment, it is found that the application scheme of our neocrown antigen detection can well detect the above mutant antigens (recombinant antigens of mainstream mutants), and the dilution can be effectively detected at 25 PG.
