Clustering of samples from differing biological fluids
(A–D) tSNE was performed on data from samples of plasma, serum, and CSF and stained with CD9, CD63, and CD81 across 39 unique capture beads and stratified by biological fluid (A), isolation method (B), and volume (C). (D) Boxplot of the top 25 capture bead and detection antibody combinations across samples showing the most significance as determined by Kruskal-Wallis.
