Protein abundance versus relative strength of the bottleneck for data from the scFv and polymerase libraries. (a) All the scFv genes; (b) all the polymerase genes. In both panels the x-axis is the relative strength of the bottleneck, the y-axis the per-cell protein abundance. Genes with bottlenecks at different relative locations are marked by different colors (see legend) to show the correlation between relative strength and protein abundance for genes with the same bottleneck location.
