10 Separation of BSA Digest on Proteomix ® SCX NP1.7 2.1 x 30 mm

Figure 14. Separation of BSA tryptic digest on Proteomix ® SCX NP1.7 2.1 x 30 mm. Mobile phase A: 10 mM phosphate buffer pH 2.5, B: A + 1 M NaCl and C: 100% acetonitrile. Flow rate was 0.35 mL/min. UV detection was set at 214 nm. 5 and 10 µg of trypsin digested BSA was injected on the column.
