Antigen Products
For over three decades, Microbix has been a leading antigen supplier with one of the most comprehensive ranges of infectious disease antigens at a commercial scale.
Childhood Disease Antigens
Microbix continues to serve as a trusted native antigen supplier for IVD industry leaders specializing in childhood disease immunological test development. Our native antigens are purified and inactivated to eliminate infectivity while maintaining antigenicity, ensuring utmost safety and satisfaction for end-users. Our comprehensive antigen panel covers rubella, varicella-zoster, P3H3 cell extract, EBV Viral Capsid Ag pure and concentrated, measles, and mumps, supporting robust assay development for childhood disease testing..
Dengue Antigens
Microbix’s dengue panel covers all four serotypes (DENV-1, DENV-2, DENV-3, DENV-4), designed both for use in assays to detect the presence of antibodies against dengue virus and as a positive control for the presence of dengue antigens in a sample. These products are formulated in a buffer that should not interfere with conjugation chemistries that are typically used in immunoassay development. Using the Microbix native dengue virus enables superior detection of all dengue proteins in diagnostic testing.
ToRCH Antigens
ToRCH infections (including toxoplasmosis and other (varicella-zoster virus), rubella virus, cytomegalovirus, and herpes simplex) virus), are common etiologic agents of congenital abnormalities. Microbix’s highly stable, specific, and sensitive native antigens are derived from purified and inactivated whole viruses produced in cell culture. Our trusted antigens are used by diagnostic companies around the world to design a variety of immunoassays used in ToRCH screening.
Respiratory Antigens
Microbix’s respiratory antigen product panel covers adenovirus, respiratory syncytial virus (RSV), parainfluenza 2 & 3, Mycoplasma pneumoniae, influenza A & B, and Chlamydophila pneumoniae. As diagnostic companies continue to improve the speed and technology of their tests, they increasingly depend on high-quality antigens to drive innovation and development. Microbix’s antigens are inactivated to eliminate infectivity while maintaining antigenicity, ensuring both optimal diagnostic performance and maximum laboratory safety.
Other Antigens
Microbix’s infectious disease antigen portfolio supports the detection of globally significant pathogens, including Borrelia burgdorferi and rotavirus Grade 3. Formulated for use in immunodiagnostic assays to detect the presence of antibodies against these diseases and as a positive control, these native antigens are purified and inactivated to eliminate infectivity while preserving antigenic integrity. This ensures high diagnostic accuracy alongside enhanced biosafety, supporting reliable test results.
STI Antigens
Microbix’s STI antigen panel includes Chlamydophila trachomatis and Herpes Simplex Virus types 1 and 2, which are among the most common pathogens associated with sexually transmitted infections. These native antigens are purified and inactivated to eliminate infectivity while preserving antigenic integrity. This ensures the accuracy and reliability needed for the development of immunodiagnostic tests.
