RESUMO
The 104-S monoclonal antibody immunoprecipitated from herpes simplex virus type 2 (HSV-2)-infected cell extracts the 75,000-molecular-weight glycoprotein gF and its 65,000-molecular-weight precursor (pgF). The precursor pgF was sensitive to endoglycosidase H digestion, indicating the presence of high mannose-type oligosaccharides, whereas the stable gF product was sensitive to neuraminidase digestion, indicating the presence of sialic acid residues. The 104-S antibody also weakly precipitated the 130,000-molecular-weight herpes simplex virus type 1 (HSV-1) glycoprotein gC from both infected cell extracts and purified preparations obtained through the use of monoclonal antibody-containing immunoadsorbent columns. Immunofluorescence tests demonstrated that the 104-S antibody reacted with antigen present in cells infected with HSV-2 strain 333 and HSV-1 strain 14012 but not with antigen present in cells infected with HSV-1 strain MP, a strain deficient in HSV-1 gC production. These findings indicate that HSV-1 gC and HSV-2 gF have antigenic determinants that are related.
