Dataset Summary
TitleBAC-DROP: Rapid digestion of proteome fractionated via dissolvable polyacrylamide gel electrophoresis and its application to bottom-up proteomics workflow
DescriptionThe 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 digestion in a gel, resulting in more than 20 hours of sample preparation for LC-MS. In this study, we overcame the limitations of GeLC-MS by developing a rapid digestion workflow for PAGE separation proteins using N,N'-bis(acryloyl)cystamine (BAC) cross-linked gels that can be solubilized by reductive treatment. Making use of an established workflow called BAC-DROP (BAC-gel dissolution to digest PAGE-resolved objective proteins), crude proteome samples were fractionated based on molecular weight by BAC cross-linked PAGE. After fractionation, the gel fragments were reductively dissolved in under 5 minutes, and in-solution trypsin digestion of the protein released from the gel was completed in less than 1 hour at 70 °C, equivalent to a 90–95 % reduction in time compared to conventional in-gel trypsin digestion. The introduction of the BAC-DROP workflow to the MS assays for inflammatory biomarker CRP and viral marker HBsAg allowed for serum sample preparation to be completed in as little as 5 hours, demonstrating successful marker quantification from a 0.5 μL sample of human serum. Combining reduced proteome complexity via PAGE fractionation with rapid trypsin digestion provides a unique opportunity for conducting high-throughput analysis of in-depth proteome with a focus on specific molecular weight ranges.
