One-Step PCR-realtime™ SARS CoV-2 E-ROX, ORF1ab-FAM and N-CY5 Genes
Multiplex OneqPCR- Raltime TM SARS CoV-2 (E, ORF1ab and N genes) amplifies and detect the E gene (SARS CoV-2), ORF1ab gene (SARS CoV-2), N gene (SARS CoV-2) and RP gene (Rnase P human) in Single One Step RT-PCR Reaction.
The kit contain Primer & Probe Mix for the detection of E gene (ROX), ORF1ab gene (FAM), N gene (CY5) and Rp gene (HEX)
Positive Control for the amplification of the E gene, ORF1ab gene and N gene is also included.
The One qPCR Enzyme Mix includes Reverse Transcriptase, Recombinant Ribonuclease Inhibitor in an optimized formulation, also include Bioingentech® Taq DNA polymerase and all reagents for an optimized RT-qPCR. The SARS CoV-2 (E-ORF1ab-N gene) primer and probe mix provided in the kit hybridize in specific and conserved zones of two genes. The first one is E gene which generate an envelope protein which plays a central role in virus morphogenesis and assembly, ORF1ab which generates a replicase polyprotein involved in the virus transcription and replication, on the other hand, N gene which facilitate its replication and process the virus particle assembly and release.
These genes can be detected through your real time platform by the 5’ nuclease PCR detection method. During PCR amplification, forward and reverse primers hybridize to the SARS CoV-2 target cDNA generated. Fluorogenic probes are included in the same reaction mixture. E gene is amplified and detected in ROX channel; ORF1ab gene is amplified and detected in FAM channel and N gene is amplified and detected in CY5.
An additional primer/probe set to detect the human RNase P gene (RP) as internal control to monitor PCR inhibition is also included in the panel labeled with a 5-reporter and a 3-quencher. During PCR amplification, the probe is cleaved and the reporter dye and quencher are separated. As a result, a fluorescence increase can be detected on a range of real time PCR platforms through HEX/VIC channel.
Figure 1: Clinical tests of the One Step PCR-realtime™ SARS CoV-2 E-ROX, ORF1ab-FAM and N-CY5 Genes detection Kit were performed with more than 5000 samples from asymptomatic and symptomatic patients.
Total RNA was isolated followed by a One Step RT-PCR for the detection of the SARS CoV-2 E gene, SARS CoV-2 ORF1ab, SARS CoV-2 N gene and the human RNase P gene.
