Figure 5: Pie chart of the top 10 proteins with the highest number of PSMs under each condition (Seppro® IgY14, HLB Oasis®, PHM-L LIPOSORB™ and unfractionated CSF). Note that albumin was at the top of the list for all conditions but IgY14. The LIPOSORB™ distribution was remarkable due to the presence of lipoproteins in the top 10, while the HLB Oasis® distribution detected a protein usually found in low concentrations in CSF (secretogranin).
