Screening of recombinase polymerase amplification combined with lateral flow test probes.
1: ipaH probe1, 2: ipaH probe2, N1: ipaH probe1 negative control, N2: ipaH probe2 negative control. Probe 1 showed a positive result. In negative control 1, only the control line changed color, indicating it was a valid control. Probe 2 produced very obvious false positive results.
