The spread of the new variant “Omicron” is faster than expected. The countries and regions with reported Omicron cases on the GISAID website have been increased to twenty-one on Dec. 2, 2021. The data only showed the number of submitted sequenced cases, which might be just the tip of the iceberg.
Facing this more contagious variant, not only our real-time PCR kits but also our antigen rapid test kit stay reliable and effective. After an in-silico analysis and simulation experiment with recombinant proteins, although the Omicron has mutation sites on the Nucleocapsid Protein of SARS-CoV-2, there is no influence on the detection region of Bioperfectus Novel Corona Virus (SARS-CoV-2) Ag Rapid Test Kit. Therefore, our kit effectively shows no drop-off in sensitivity and specificity in face of the Omicron variant.
