Purification of glycoprotein gD of herpes simplex virus types 1 and 2 by use of monoclonal antibody

Abstract

Glycoproteins gD-1 and gD-2 of herpes simplex virus types 1 and 2, respectively, were purified on an immunoadsorbent consisting of the type-common monoclonal antibody HD-1 linked to Sepharose. Each glycoprotein was of sufficient purity, quantity and biological activity to be used for immunological and biochemical studies. Each glycoprotein induced high titers of type-common monospecific neutralizing antibody in mice. Amino acid analysis indicated that gD-1 and gD-2 had similar though not identical amino acid compositions.
