Transcriptional alterations in kinase genes detected by microarray analysis at 6, 24, 48 and 72 h post IBV infection. RNA used in these experiments was derived from lung tissues of IBV infected and sham inoculated 18 days old chick embryo. Procedures for probe synthesis and array hybridization have been described in methods. Fold change in expression of genes represents the mean value derived from two independent experiments with hybridizations performed three to four times with RNA isolated from each experiment.
