A Draft Map of E. coli Proteoforms

Top-down proteomics (TDP) enables direct characterization of intact proteoforms, providing protein-level insights into molecular diversity arising from post-translational modifications and sequence variations. Despite this advantage, proteome coverage in TDP remains limited relative to bottom-up proteomics (BUP). To ex...

Proteoform Barcode: An Intuitive Visualization Framework for Top-Down Proteomics

Top-down proteomics (TDP) advances biomedical research by providing a bird’s-eye view of proteoforms in cells, tissues, and biofluids. Thousands of proteoforms can be characterized using well-established TDP technologies, and potential proteoform biomarkers of diseases have been discovered. However, there is a lack of...

Combining SDS-PAGE with Capillary Zone Electrophoresis-Tandem Mass Spectrometry for Top-Down Proteomics Analysis of Intact Histone Proteoforms.

The combination of SDS-PAGE-based protein fractionation with CZE-tandem MS (MS/MS) for high-resolution characterization of histone proteoforms from a commercial calf thymus histone sample was described.
