  • Title: Production of polyclonal antisera against cytomegalovirus and varicella-zoster virus by use of affinity-purified viral antigens.
    Author: Ukkonen P.
    Journal: APMIS; 1989 Mar; 97(3):267-73. PubMed ID: 2540778.
    Abstract:
    Specific animal antisera to cytomegalovirus (CMV) and varicella-zoster virus (VZV), devoid of antibodies to host cell components, have been difficult to prepare because of the cell-associated nature of these viruses. A simple method for the purification of CMV and VZV antigens is described in this paper. The viral antigens were purified from commercially available crude antigens by affinity chromatography with human antibodies against CMV and VZV. Rabbits were immunized with the purified antigens. The produced antisera were specific for the respective viruses and did not contain antibodies to host cell components, as determined by immunofluorescence microscopy and enzyme-immunoassay. The antisera have been used for direct detection of viral antigens in clinical specimens and for identification of cytopathic effect in cell cultures by immunofluorescence microscopy. The CMV antiserum could also be used for the early detection of CMV in cell cultures inoculated with patient specimens, but it was less sensitive than a monoclonal antibody to the early antigen of CMV.
