Figure 3From: Protein profiling reveals inter-individual protein homogeneity of arachnoid cyst fluid and high qualitative similarity to cerebrospinal fluidArachnoid cyst protein comparison experiment (top 50 proteins). Principal component analysis (PCA) of individual AC fluid LC-MS/MS results, normalized to sample sum. The figure is based on evaluation of top 50 proteins on protein score. Axis labels are weights of axes, the amount of total variance explained by the PC. The percentage of variance explained by the first two PCs is 48%. Observe that patients 3 and 4, as well as 12 and possibly 9 were apart from the other patients.Back to article page
