ProteomicsUpdated in-gel digestion for protein analysis by mass spectrometry
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...

ProteomicsCBB staining showed beneficial effects on proteomic analysis employing PAGE separation followed with whole-gel slicing, in-gel digestion and quantitative LC-MS/MS
Proteomic analysis by combining PAGE separation, gel slicing and slice-by-slice LC-MS/MS has been frequently reported in recent years. Since the MS analysis would provide identities and quantities of the proteins along the whole lane, visualization by dye staining could be skipped to save time and ...

ProteomicsQuantitative assessment of the effects of trypsin digestion methods on immunoprecipitation-mass spectrometry-based protein-protein interaction analysis
Immunoprecipitation-mass spectrometry (IP-MS) has become the method of choice for discovering protein-protein interaction (PPI) under native conditions. The success of the IP-MS depends on the efficiency of trypsin digestion and recovery of the tryptic peptides for MS analysis. Several different pro...

ProteomicsProteomics Using Proteases Alternative to Trypsin Benefits from Sequential Digestion with Trypsin
High specificity and ease of use make trypsin the most used enzyme in proteomics. Proteases with complementary cleavage specificity to trypsin have been applied to obtain additional data. However, use of proteases with broad specificity proved especially challenging. In this work, we analyzed the ch...

ProteomicsBAC-DROP: Rapid digestion of proteome fractionated via dissolvable polyacrylamide gel electrophoresis and its application to bottom-up proteomics workflow
The GeLC-MS workflow, which combines low-cost, easy-to-use SDS-polyacrylamide gel electrophoresis (SDS-PAGE) with liquid chromatography-mass spectrometry (LC-MS), is very popular in current bottom-up proteomics. However, GeLC-MS requires that PAGE-separated proteins undergo overnight enzymatic diges...

ProteomicsComparison of in-gel digestion methods for histone PTM analysis
In order to optimize the histone digestion procedure for low-abundance clinical samples, we compared different in-gel digestion protocols. Histones are usually digested in-gel using “Arg-C-like” strategies, which involve chemical acylation of lysines followed by trypsin digestion (17). Acylated lysi...

ProteomicsIdentification of zein proteome by multi-enzyme digestion
Zeins are a class of prolamine proteins extracted from maize, and are extensively used in the food and pharmaceutical industries. Therefore, characterization of its components is essential for quality control and safety evaluation. However, zein proteins have low abundance of the trypsin targets lys...
