Figure 1: mRT-PCR amplification Result: 1% Agarose Gel Electrophoresis of mRT-PCR amplified products of individual CAM +field samples. Here, Lane L, ladder (100 bp Marker); Lanes R16, R2, R3, R5, R20 and R65 are for field isolates; Lane N, negative control. Here, band at 1023 bp is indicative of AIV, 647 bp for ILTV, 320 for NDV and 149 for IBV infection.
