Analysis using 2-DE of chicken embryo tracheal tissues from the IBV-infected group compared with the mock-infected group using the pH 4-7 range. Protein samples were separated on 13 cm pH 4-7 IPG strips, followed by SDS-PAGE, and stained with Coomassie Blue R-350. The images were analyzed using Image Master 2D Platinum 6.0 software. The different protein spots identified were marked with a circle and a number. The numbers assigned to the mapped protein spots correspond to the proteins listed in Table 1.
