The kit is used for in vitro qualitative detecting the ORF1ab/N/S genes of novel coronavirus 2019-nCoV in respiratory specimens including oropharyngeal swabs, nasopharyngeal swab, sputum and performing mutation typing on HV69- 70 del simultaneously. As reported in GISAID database, more than 95% Omicron variant sequences reported include a deletion in the HV69-70, which can cause an S gene target failure (SGTF) in PCR assays. SGTF can be used as a proxy marker to screen for Omicron.
Primer sets and FAM labeled probe are designed for specific detection of ORF lab gene of 2019-nCoV, VIC labeled probe for N gene of 2019-nCoV, ROX labeled probe for S gene HV69-70 del mutation of 2019-nCoV. Human RNase P gene extracted concurrently with the test sample provides an internal control to validate nucleic extraction procedure and reagent integrity. Probe targeting human RNase P gene is labeled with CY5.
