Figure 4: A: Venn diagram with the number of unique proteins identified in the different conditions (Seppro® IgY14, HLB Oasis®, PHM-L LIPOSORB™ and unfractionated CSF). Note that the number of proteins detected by only one method was as high as the number of proteins detected by several methods. 4B: Hierarchical clustering according to the number of unique protein identifications for each pre-2 method (Seppro® IgY14, HLB Oasis®, PHM-L LIPOSORB™) and for unfractionated CSF. Unfractionated CSF is well separated from the different pre-fractionations, while IgY14 and PHM-L LIPOSORB™ were closer together.
