What ViroStat does
ViroStat LLC was a US-based developer and manufacturer of infectious disease antibodies and antigens supplied as raw materials to in vitro diagnostics (IVD) manufacturers. Its product catalog centered on three technology families: MonoTope monoclonal antibodies, OmniTope polyclonal antibodies, and a broad set of native and recombinant antigens used in immunoassay development, quality control, and clinical research. Customers are IVD OEMs building diagnostic test kits for infectious disease detection, where ViroStat's reagents are qualified into the manufacturers' regulated assay workflows.
The company monetized through one-time sales of biological reagents to enterprise diagnostics manufacturers rather than licensing or recurring subscription models; pricing is handled privately through sales representatives rather than publicly disclosed. Following its November 2023 acquisition by Finnish-headquartered IVD raw materials supplier Medix Biochemica, ViroStat's products are now sold and supported through Medix Biochemica's global sales infrastructure covering the US, Europe, the rest of the world (via Medix Biochemica USA Inc), and China, Taiwan, and Hong Kong (via Medix Biochemica China), with online ordering available through Medix Biochemica's e-commerce platform. Integration was completed on October 1, 2024, when product catalogue numbers were migrated to Medix Biochemica's ERP system (with a 'V' prefix added), order processing was rerouted, product specifications and certificates of analysis were realigned to Medix Biochemica templates, and ViroStat branding on all sales, quality, and labeling documents was replaced with the Medix Biochemica brand. As a result, ViroStat now functions as a product line within Medix Biochemica's broader IVD raw materials portfolio rather than as an independent operating entity.
