Title	Multi-dimensional native proteomics technology for protein complex identification and topology characterization (Mud-NatPIT)
Description	Here, we demonstrate a pilot development of multi-dimensional native proteomics technology for protein complex identification and topology characterization (Mud-NatPIT) in complex biological samples via coupling native size exclusion chromatography (SEC), online native capillary electrophoresis-mass spectrometry (nCE-MS), surface-induced dissociation (SID), and multi-level proteomics. The Mud-NatPIT enabled the detection of 124 unique native endogenous protein complexes with masses up to 1.5 MDa from a whole cell lysate, identified 46 unique protein complexes in a discovery mode, and provided topological information for 39 protein complexes. The Mud-NatPIT is broadly applicable for characterizing protein complexes in cells, tissues, and biological fluids.

Dataset FTP location NOTE: Most web browsers have now discontinued native support for FTP access within the browser window. But you can usually install another FTP app (we recommend FileZilla) and configure your browser to launch the external application when you click on this FTP link. Or otherwise, launch an app that supports FTP (like FileZilla) and use this address: ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2026/08/PXD069439
