The accumulated numbers of protein group and unique peptide IDs from the mouse brain proteome digest vs. the number of SCX-RPLC fractions. Two salt steps were employed for step-wise elution of peptides from the SCX to the RPLC. CZE-MS/MS with a 94-cm separation capillary was used for analysis of the 40 SCX-RPLC fractions.
