Vero cells infected with rCDV-SIVgag1.
CT, threshold cycle number at which fluorescence was detected above the background. Positive CT values are ≤40 while negative CT values are >40 and are shown by a dash line.
Separate singleplex reactions for CDV N and SIV-gag were carried out in different wells with specific primer-probe sets.
Duplex reactions for CDV N and SIV-gag were done in the same wells containing primer-probe sets specific for both genes.
