SCICONS, is the leading supplier of mouse monoclonal J2, K1 and K2 antibodies that bind to double-stranded RNA molecules. The Scicons antibodies have been used extensively to detect and characterise plant and animal viruses with dsRNA genomes or intermediates (including Hepatitis C, Dengue, West Nile Virus and SARS). These anti-dsRNA antibodies can be used as a diagnostic tool to detect whether an unkown pathogen is bacterial or viral in nature, including detection in paraffin-embedded fixed tissue samples.
