Fig. 6From: Development of a simplified RT-PCR without RNA isolation for rapid detection of RNA viruses in a single small brown planthopper (Laodelphax striatellus Fallén)Comparison of the sensitivity of simplified RT-PCR (Crude) and traditional RT-PCR (Trizol). a PCR products amplified from samples prepared by the two methods. b Relative RSV abundance evaluated by gray value of PCR products. c Relative RSV abundance evaluated by qRT-PCR in the samples ground by toothpick. d Relative RSV abundance evaluated by qRT-PCR in the samples ground in nitrogen liquidBack to article page
