Sensitivity of the RT-RPA-LFS and qPCR assays. Serially diluted RNA standards were used to determine the sensitivity of the RT-RPA-LFS (A) and qPCR (B) assays. Serially diluted spiked-in samples were used to determine the sensitivity of the RT-RPA-LFS (C) and qPCR (D) assays. a, 1.0 × 100 copies; b, 1.0 × 101 copies; c, 1.0 × 102 copies; d, 1.0 × 103 copies; e, 1.0 × 104 copies; f, 1.0 × 105 copies; g, 1.0 × 106 copies; BC, blank control.
