Abstract: The present invention relates to a method and kit for detecting antibodies in clinical samples of animals infected with equine infectious anemia virus using the immunodiagnosis with the recombinant viral antigen p26. The antigen was bound to solid supports (microtitter plates, tubes, beads or nitrocellulose papers or nylon) and reacted with the test serum. After incubation with conjugated anti-equine immunoglobulin-enzyme the reaction was revealed with a solution composed of the substrate of the enzyme used in the conjugate (cromogene). After development of the reaction (color formation) it was stopped with acid solution and measured. The immunoassay may be a direct second antibody immunoassay, a one or two step sandwich immunoassay.

Abstract: The invention provides a new human interferon (IFN)-&bgr; variant cloned from an amniotic cell library, a cDNA encoding it, and processes for its production and purification. The variant, termed interferon beta-cis, differs from previously known hIFN-&bgr; isoforms by the substitution of a Cys residue for the Tyr present at position 60. Recombinant IFN beta-cis exhibits antiviral activity characteristic of IFN-&bgr;.
