This Antigens panel covers Rubella, Varicella-Zoster, P3H3 Cell Extract, EBV Viral Capsid Ag Pure and concentrated, Measles and Mumps.

Dengue Antigens

Microbix’s dengue panel covers Dengue Types 1, 2, 3 and 4 for use suitable in assays for detection of presence of antibodies against the Dengue type virus, and as a positive control for the presence of Dengue type virus 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 in dengue diagnostic assays provides superior identification of all dengue proteins.

STI Antigens

STI infections Antigens panel include Chlamydophila trachomatis, Herpes Simplex 1 and 2

ToRCH Antigens

ToRCH infections, including Toxoplasmosis, Other (Varicella Zoster virus, Syphilis, and Parvovirus B19), Rubella Virus, Cytomegalovirus, and Herpes Simplex Virus), are common etiologic agents of congenital abnormalities.
