Characterization of rescued viruses. (a) Amplification of IBV H120-specific cDNA fragments from different generations of rH120 and rH120/SCS1 passaged in SPF chicken embryonated eggs. 1–3, The first three generations of rH120. 4–6, The first three generations of rH120/SCS1. (b) H120, rH120, and rH120/SCS1 infected CEK cells detected by IFA with mAb against IBV M protein. (c) Western blot analysis of H120, rH120, and rH120/SCS1 infected chicken embryonic allantoic fluid with mAb against IBV M protein
