Identification of AIV Type A by amplification of coding region of NP gene using RT-PCR. Viral RNA extracted from HA positive samples (allantoic fluid) were employed to amplify coding region of NP (nucleoprotein) gene using specific primer pair. The arrow in agarose gel image indicates amplified NP gene (330 bp). Lanes M, size marker; S1 and S2, test samples; N, negative control; P1 and P2, positive control (NP gene as template).
