Expression of JEV prM and Env genes in TELCeB6 cells. TELCeB6 cells were transfected with pHCMV-prM/E and pHCMV-E of each of NK and BJ strains. RT-PCR products of the indicated size were amplified from total RNA samples extracted from TELCeB6 cells. The products correspond to 2 Kb of prM (amplified by prM/E primer) and 1.5 Kb of Env (amplified by E primer). The molecular marker (Kb) is shown on the left.
