A novel on-line 2-D system was developed for peptide and protein mapping. The system combines capillary IEF (cIEF) with pressurized CEC (pCEC) using a micro-injection valve as the interface. Sample fractions, which were focused and separated in the firstdimension cIEF based on their differences in p
## Abstract A comprehensive twoβdimensional (2βD) separation system, coupling capillary reverseβphase liquid chromatography (cRPLC) to capillary isoelectric focusing (CIEF), is described for protein and peptide mapping. cRPLC, the first dimension, provided highβresolution separations for saltβfree
