A chemiluminescence electrophoretic mobility shift assay was introduced for the study of RNA-protein interactions that include association of genomic RNA and viral capsid proteins. Binding of the capsid protein of Venezuelan equine encephalitis virus (VEEV) to several types of RNA was used as a model system to test the application of the method. The effects of RNA secondary structures and the significance of electrostatic interaction on binding were identified. This method may have wide application to the study of RNA-protein interactions.
