Invitrogen™ IFNAR2 Monoclonal Antibody (MMHAR-2)

Mouse Monoclonal Antibody

This antibody neutralizes human IFN-alpha receptor, interacting with the extracellular domain. It binds to human IFN-alpha receptor with high affinity and blocks biological action of Type I IFNs. To measure bioactivity, interferon was titrated with the use of a cytopathic effect inhibition assay, where one neutralization unit is the amount of antiserum required to neutralize one unit of human interferon alpha to a 50% endpoint. In this antiviral assay, approximately one unit/mL of interferon was necessary to produce a cytopathic effect of 50%. Purity is >95% by SDS-PAGE and endotoxin level <1 EU/ug. Store at -20°C for up to 6 months. For long-term storage, store at -70°C for retention of full activity. Thaw product by incubation in cold water and aliquot into separate vials, adding 0.1% BSA for additional stability. Refreeze product using a dry ice or a dry ice/alcohol bath.
