ViroLabs, Inc. provides a series of purified recombinant antigens for infectious disease research. SARS-Cov, HIV, HTLV and Hepatitis viruses are our main areas. Most antigens are the surface antigens or capsid proteins from different viruses. All of these viral antigens have been tested by our scientists to assure their purity and stability. These recombinant antigens, when used coating reagents, yielded comparable results with diagnostic kits from leading providers. For most of the antigens, we also have the corresponding monoclonal antibodies. Cat.
