Figure 6

Pie charts of total CSF proteins identified by high resolution liquid chromatography mass spectrometry from a single shotgun sequencing run of S3 and P3 fractions of two different samples #s 3 and 3' from one participant (Table 1). Data was pooled for both P3 and S3 fractions, and charted as S3 or P3 GO components (same code as in Figure 2). There are a number of differences between the P3 and S3 fractions (for complete protein lists see Additional File 2). The GO components that differentiate the two fractions have directional arrows, from which it is clear that there are more structural (GO #s 4 & 10) and "other" category proteins (GO # 3), and less extracellular proteins (GO # 11) in P3 fractions.
