Figure 4From: Rapid detection of porcine kobuvirus in feces by reverse transcription loop-mediated isothermal amplificationThe specificity of RT-LAMP and RT-PCR. (A) The RNAs of TGEV, PEDV, A group PoRV, PEV 9 and PTV were added to the RT-LAMP reaction, no ladder-like bands appeared. M, 2000 bp DNA marker; (B) SYBR green I dye (1:1000, 1 μl) was added to LAMP reaction and exposed to UV light. Only the PKV tube showed green fluorescence. (C) The specificity of RT-PCR. PC: positive control; NC, negative control.Back to article page
