Native mumps virus preparation Native mumps virus contains a high concentration of virus and viral components. The preparation also contains some cellular material suspended in tissue culture medium (1969B). Mumps virus is a member of the Paramyxoviridae family and is the causative agent of mumps. Mumps is most typically characterised by painful swelling of the salivary glands and fever. In some adult men, the virus might also infect the testicles, rarely causing sterility. The virus is spread by airborne droplets from the nose or throat and can have an incubation period of up to three weeks. Infected individuals are contagious from approximately 6 days before until about 9 days after the onset of symptoms. The disease is self-limiting and treatment involves controlling specific symptoms. An effective vaccine exists and may be given separately or as part of the MMR vaccine. Mumps virus, Enders strain, cultured in BSC-1 cells. Activity: Antigenic activity is 124% of internal reference batch Applications: Suitable for use in ELISA. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Note: M9215-20D should be sonicated immediately before use to ensure the preparation is uniform. The product may be used in a variety of immunoassay formats or may be further purified to meet the requirements of a particular assay format. Inactivation: Inactivated using gamma radiation, which primarily damages viral genetic material. Storage and Stability: Aliquot to avoid repeated freezing and thawing and store at -70C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
