Abstract

The total viral structural polypeptides and the double-stranded genomic RNAs of bluetongue virus can be selectively separated by a single SDS-KCl precipitation step. This simple, rapid and highly reproducible method enables greater than 95% recovery and purity of both viral proteins and dsRNAs within 30 min. The serotypic identity of the separated dsRNAs can be analyzed by SDS-PAGE electrophorogram immediately. After a single phenol/chloroform extraction, the dsRNA can also be used as hybridization probes, templates for molecular cloning and direct RNA sequencing. The SDS-KCl-precipitated viral proteins could be used readily for peptide mapping and as immunogens. Polyclonal and monoclonal antibodies raised against SDS-KCl-precipitated viral structural polypeptides were useful in Western immunoblots.
