Cytokine Stimulated Vs Unstimulated

human bronchial smooth muscle cells were growth arrested. One group was stimulated with 10ng/mL of IL-1beta, TNF-alfa, and gamma IFN for 20 hours. For every cDNA sample, 2 dyeflipped slides were hybridized (these have the same date in the titles). All cy3 (channel 2) measurements were normalized to the dye coupling control before a ratio of the values was taken.
