PANDAA qDx SARS-CoVar [Variant Genotyping]
SARS-CoV-2 detection and allelic discrimination of variant mutations – including Omicron.
Questions? email us: COVID19@aldatubio.com
- A focused genotyping approach of the S gene of SARS-CoV-2 that is more time and cost-effective than sequencing for COVID variant genotyping.
- Using a combination of fluorescent probes in two multiplex PANDAA reactions, each of the eight variants has a distinct fluorescent signature that allows them to be accurately differentiated:
-
- Non-variant [i.e. Wuhan strain]
- Variants of Concern
- Alpha
- Beta
- Gamma
- Delta
- Omicron
- Variants of Interest
- Epsilon
- Zeta
- Eta
- Theta
- Iota
- Kappa
-
- Fast – delivers accurate results from RNA in 1 hour
- Sensitive to < 100 copies
- Platform-agnostic – compatible with sample prep and qPCR platforms in most labs.

Principles
Variant Signature Assays
Using two multiplex qPCR reactions, each of the eight variants has a distinct fluorescent signature that allows them to be accurately differentiated. Both reaction mixtures contain an optional internal control that is detected by a Cy5-labelled probe.
| Assay | Detection Channel #1 | Detection Channel #2 | Detection Channel #3 |
|---|---|---|---|
| Variant Signature #1 | K417N N501 | N501Y | K417 |
| Variant Signature #2 | E484KQ T478K | L452R | E484A |
Compatible Real-Time PCR Instrumentation
Any qPCR instrument that is capable of detecting FAM, VIC and NED fluorophores, with or without the passive reference dye, ROX. For use of the internal control, the instrumentation must be capable of detecting the Cy5 fluorophore.
