ProteomicsOn-capillary cell lysis enables top-down proteomic analysis of single HeLa cells by CE-MS/MS
Proteomic analysis of limited samples and single cells requires specialized methods that prioritize high sensitivity and minimize sample loss. Consequently, sample preparation is one of the most important steps in limited sample analysis workflows to prevent sample loss. In this work, we have elimin...

ProteomicsCapillary electrophoresis coupled to electrospray ionization tandem mass spectrometry (CE-MS/MS) for ultra-sensitive proteomic analysis of limited sample
In this work, we developed an ultra-sensitive CE-MS/MS method for bottom-up proteomics analysis of limited samples, down to sub-nanogram levels of total protein. Analysis of 880 pg and 88 pg of HeLa protein digest standard by CE-MS/MS yielded ~1,100±46 and ~160±59 proteins, respectively, demonstrati...

ProteomicsCoupling high-field asymmetric ion mobility spectrometry with capillary electrophoresis-electrospray ionization-tandem mass spectrometry improves protein identifications in bottom-up proteomic analysis of low nanogram samples
In this work, we pioneered the assessment of coupling high-field asymmetric waveform ion mobility spectrometry (FAIMS) with ultra-sensitive capillary electrophoresis hyphenated with tandem mass spectrometry (CE-MS/MS) to achieve deeper proteome coverage of low nanogram amounts of digested cell lysa...
