aSpectral counts refer to the average spectral counts from two independent MS runs with an FDR cutoff of 0.05.

The table lists proteins common to chromate stressed, M9L and LB grown cells. The proteins were selected on the basis of their Poisson regression score and an FDR of 0.05. Spectral counts for each protein show the proteins to be uniquely expressed in chromate-stressed cells only.
