Quantification of differentially expressed proteins in <i>R. eutropha</i> H16 and mutant <i>R. eutropha</i> PHB^-4 as based on image fusion of 2D PAGE gels (Fig. 2).

<p>Spot quantities are given as % volume (representing the relative portion of an individual spot of the total protein present on the respective average fusion image). To facilitate comparision of spot quantities, panel A presents spots with relative quantities close to 1, while spots with higher quantities are shown in panel B. Quantification was done with Delta 2D software. Suffixes (a, b, and others) indicate isoforms of the same protein species present in the gels.
