Amplification of VP1 genes of EV71 isolate S2/86/1 and isolate 410/4 by PCR. Lane M shows a 1 kb molecular marker (Fermentas). Lane 1 and lane 3 each shows a band of size 923 bp, which represent the PCR product of VP1 gene of EV71 isolate S2/86/1 and isolate 410/4, respectively. Lane 2 and lane 4 which show no band of PCR product are PCR negative controls that used water as template.
