Figure 2From: The morphology and biochemistry of nanostructures provide evidence for synthesis and signaling functions in human cerebrospinal fluidPie charts of total CSF proteins identified by LCMS from 15 replicates of shotgun sequencing of S1 fractions from two different participants (sample #s 1 and 2, Table 1) and charted as GO components. There was a similarity between the two samples (complete protein lists are in Additional File 1). The principal groups of interest are the large percent of membrane proteins: Plasma (1) and Other Membranes (2) that are present in both samples.Back to article page
