Tm: temperature, Locked-Nucleic Acid bases are written as ‘ + _’, e.g., +A.
Degenerate bases: R = (A/G), W = (A/T), K = (T/G), Y = (C/T), N = (A/G/T/C).
^a S: sense orientation, AS: antisense orientation.
^b YFV strain; accession no: NC 002031.
^c Flavi all probe, ^d Flavi probe YFV, ^e Flavi probe DEN4.
Final Pan-Flavi assay comprise of Flavi all S, Flavi all S2 & Flavi all AS4 primer and Flavi all probe 3 mix.
