Midnight Primer sequences
As mutations in SARS-CoV-2 variants emerge amplicon drop out may be observed; for users wishing to design their own primer spike-ins to address this we suggest adding to the appropriate primer pool at a final concentration between 3.33 µM and 6.66 µM.
Below are the sequences for the V3 primer scheme used in the Midnight RT PCR Expansion.
