Figure Lengend Snippet: PreOmics ENRICH‐iST demonstrated superior enrichment efficiency, identifying more pathways at greater statistical significance as well as pathways relevant to neuropathologies. Comparison of FDR‐adjusted p values (−log 10 scale) showed the PreOmics ENRICH‐iST Kit (‘PreOmics’, red) generally achieved more significant values across the analysed GO pathways compared to the native digestion (‘Native’, blue) and ProteoMiner Small‐Capacity Enrichment Kit (‘ProteoMiner’, green). Out of the 50 pathways analysed, 22 were identified at a lower FDR by PreOmics ENRICH‐iST. Dashed vertical lines indicate the mean –log 10 (FDR) for each technique (Native: 10.3 ± 3.76; PreOmics: 12.0 ± 5.63; ProteoMiner: 11.5 ± 4.55), with shaded regions representing ± 1 standard deviation and dotted lines marking the boundaries of each distribution.

Article Snippet: Here, we compared three different approaches to prepare CSF samples for proteomic LC–MS/MS analysis: our laboratory protocol for in‐solution trypsin digestion (native digestion; Anderson et al. ), Bio‐Rad's ProteoMiner Small‐Capacity Enrichment Kit, and the PreOmics’ PreOmics Enrich‐iST Kit.
