Supplying Researchers and Manufacturers Since 1985

ViroStat was founded in 1985 by Dr. Douglas McAllister to provide infectious disease antibody tools to researchers and manufacturers. These include the areas of virology, bacteriology and parasitology. Applications for these include detection of respiratory agents, STD agents, gastrointestinal agents/toxins and food borne pathogens.

The company offers more than 500 infectious disease reagents including their MONOTOPE™ monoclonal antibodies, OMNITOPE™ polyclonal antibodies and numerous recombinant antigens. Many of these antibodies are used by manufacturers of rapid, point of care tests currently made and sold in the US.

Because ViroStat is the primary manufacturer of these antibodies, they have the knowledge and experience to offer excellent customer service and technical support to your laboratory staff on any scale from 100 ug to 10 grams.
