Fig. 3From: A rapid and visual detection assay for Clonorchis sinensis based on recombinase polymerase amplification and lateral flow dipstickSensitivity of the RPA-LFD assay and PCR for the detection of C. sinensis genomic DNA. A Sensitivity of the RPA-LFD assay. Genomic DNA of C. sinensis at quantities from 100Â ng to 10Â fg was used to determine the minimum detection concentration in the LFD-RPA assay. B PCR with reported primers Cs1 and Cs2 with DNA quantities from 100Â ng to 10Â fg. NC negative control, containing no DNABack to article page
