Enhanced protein separation and analysis

Abstract

Methods for enhancing separation and analysis of biological molecules, particularly proteins, and for characterizing tissue, cell, and subcellular (e.g., organelle) expressed protein profiles (proteomes or protein fingerprints) are disclosed. Multi-dimensional diagrams that illustrate the characteristics of the proteins in a sample, based at least in part on interactions between proteins in the system can be produced. In certain embodiments, the diagrams are three-dimensional and incorporate information on protein-protein interactions, protein charge, and protein size for substantially all of the protein species in the sample. Also described are methods of using the provided multi-dimensional diagrams to detect changes in biological systems that are for instance due to disease, drug treatment, environmental condition, and so forth. Methods are provided for correlating changes in three-dimensional proteomic diagrams to disease diagnosis and prognosis, toxicology, therapeutic compound (e.g., drug or hormone) efficacy and mode of action, and drug design.
