Extended Data Fig. 2

After RAW264.7 cells were infected with STm for 20 hours, the conditioned media was removed and indicated cytokines and chemokines were quantified using a custom array (Biocat, GmbH). n denotes the combined data from 2 independent experiments (batches), each batch containing 2 biological replicates per condition. Box boundaries indicate the upper and lower IQR, the median is depicted by the middle boundary and whiskers represent 1.5x IQR. Relative infected/uninfected Δ (Log2) from the cytokine array are depicted within the plot for each protein. Corresponding pSILAC-AHA infected/uninfected (Log2) ratios are presented below the corresponding protein for the 20hr post-infection time-point (with the exception of TNFa, which we could only detect at 8 hpi). Non-hits and hits match perfectly between the 2 methods. Fold effect differences between pSILAC-AHA and array-based quantification are most likely due to the fact that the cytokine assay measures steady-state protein levels and pSILAC-AHA newly synthesized proteins. As expected, for more abundant proteins, measuring steady-state levels masks changes in expression dynamics. A two-sided unpaired t-test was used to calculate p..
