A: Venn-diagram of the biological triplicates (#1, #2, and #3) of transgenic mouse CSF showing 78 proteins identified in all three experiments. B: Venn-diagram of the biological triplicates (#1, #2, and #3) of control mouse CSF having 61 proteins identified by all three replicates. C: The overlap between control and transgenic CSF proteomic analysis showing 139 proteins identified by both groups, and 73 and 54 uniquely identified by respective groups.
