We have enabled ultrasensitive proteomics of limited protein digests by developing a tapered-tip nanoelectrospray ionization (nanoESI) interface for microanalytical capillary electrophoresis (CE) high resolution mass spectrometry (HRMS). CE-nanoESI-HRMS allowed us to detect 260 zmol angiotensin II (...
