Comparison of different prefractionation strategies. Vitreous protein sample VP2 was analyzed with four different prefractionation strategies according to the work flow outlined in Figure 1. The bars represent the total number of proteins detected by each individual method. The black part of the bars represents proteins detectable with the standard procedure. The grey part indicates proteins that were detected with the variant method but were not found applying the standard procedure.
