Comparative phosphorylation intensities of selected spots in 2D gels. The intensities of selected spots in KO gels were compared with intensities in WT gels. Average intensities of the indicated spot numbers (#) in WT (white bar) and KO (black bar): #1205, 1092.2 (WT) and 244.98 (KO); #1207, 729.9 (WT) and 140.43 (KO); #3303, 1165.5 (WT) and 279.5 (KO); #4302, 2725.8 (WT) and 1 (KO); #4405, 984.5 (WT) and 1 (KO). An intensity value of 1 indicates no spot, but is provided for calculation of fold change.
