All shotgun proteomics experiments rely on efficient proteolysis steps for sensitive peptide/protein identification and quantification. Continuous protocol improvement is therefore a constant topic in proteomics research. Previous reports suggest that the sequential tandem LysC/trypsin digest yields...

Quantitative determination of absolute and relative protein amounts is an essential requirement for most current bottom-up proteomics applications, but protein quantitation estimates are affected by several sources of variability such as sample preparation, mass spectrometric acquisition, and data a...

The in-gel digestion of proteins for analysis by liquid chromatograph mass spectrometry has been used since the early 1990s. Although several improvements have contributed to increasing the quality of the data obtained, many recent publications still use sub-optimal approaches. We present an updated...
