    Patent number: 4514507
    Abstract: An assay for interferon comprises two antibodies to interferon, one labelled and at least one being a monoclonal antibody.

  • Monoclonal antibody to interferon-.alpha.
    Patent number: 4423147
    Abstract: A monoclonal antibody is described characterized by its specificity to interferon-.alpha. (leukocyke interferon). Preferably the antibody has specificity to human interferon-.alpha.. The monoclonal antibody is secreted by a hybrid cell formed by the fusion of lymphocyte cells derived from an animal immunized with interferon-.alpha., with mycloma cells. The antibody has applications in the purification of interferon. It may be covalently attached to a solid support and used as an immunoadsorbent. Purifications of up to 5000 fold may be obtained in a single pass through an immunoadsorption column of this type. An immunoradiometric assay for interferon-.alpha. is also described.
