Figure 2: a) the results of DAS-ELISA assay for PLRV. The positive control (5F and 10C), PLRV10 (5B, 5C and 11C) and PLRV16 (7D, 7E and 10G) are shown in green. b) Electrophoresis of the RT-PCR product on 1.5% agarose gel visualized by Ethidium Bromide staining under UV illumination. The RT-PCR reaction was carried out using PLRV specific primers and amplified a 336 bp fragment. Lanes: 1, water control; 2 PLRV10; 3 PLRV16; M, 100 bp ladder.
