iLite® Type I IFN Assay Ready Cells can be used for measuring the bioactivity of Type I Interferon or neutralizing antibodies to Interferon beta or Neutralizing antibodies to Interferon alpha.
iLite® Type I IFN Assay Ready Cells are growth arrested cells which are sensitive to human Type I Interferon. The cells can be used in a number of different assays for measuring the bioactivity of Type I Interferon or NAb’s to IFN beta or NAb’s to IFN alpha.
Type I Interferons are produced by a wide variety of cells in response to viral infection and hence the presence of type I interferon is indicative of infection. IFN alpha is routinely used to treat chronic viral hepatitis and a wide variety of malignant diseases and IFN beta is routinely used to treat multiple sclerosis. The development of neutralizing antibodies (NAb’s) to either IFN alpha or IFN beta which correlates with a loss of treatment efficacy, is relatively common 1-2. The iLite® IFN cells are the only commercially available cells capable of measuring either the bioactivity of type I interferon, NAb’s to IFN beta or NAb’s to IFN alpha.
