Lane 1 corresponds to 10 μg of purified PpuR-6His; lane 2 and lane 3 correspond to total proteins from 2 × 10cfu of WCS358(pBBRppuR) and IBE4(pBBRppuR) respectively; lanes 4 and 5 correspond to total proteins from 10cfu. For lanes 4 and 5 the images were scanned using a Versadoc (Biorad) and the QuantityOne software; results of this quantification are displayed as a histogram. See text for all details
