  • Title: Affinity capillary electrophoresis analyses of protein-protein interactions in target-directed drug discovery.
    Author: Pierceall WE, Zhang L, Hughes DE.
    Journal: Methods Mol Biol; 2004; 261():187-98. PubMed ID: 15064459.
    Abstract:
    Protein-protein interactions are instrumental in virtually all biological processes and their understanding will shed light on designing novel and effective drugs for therapeutic interventions targeting the pathways in which they function. Protein-protein interactions have been studied using many genetic and biochemical methods, most recently, affinity capillary electrophoresis (ACE). We used ACE as a high-throughput screening assay to establish and define binding interactions between a therapeutic target protein and chemical entities from natural product or synthetic chemical libraries. Furthermore, ACE has demonstrated its value in the measurement of binding constants, the estimation of kinetic rate constants, and the determination of the stoichiometry of protein-protein interactions. Herein, we will describe qualitatively several assay formats using ACE for detecting protein-protein interactions, and discuss their advantages and limitations.
