Type-common and type-specific monoclonal antibody to herpes simplex virus type 1

Abstract

Hybridoma cells produced by fusing mouse myeloma cells with spleen cells from mice primed with herpes simplex virus (HSV) type 1 yielded 5 clones producing neutralizing antibody against homologous virus. Two clones, HC1 and HC2, produced antibody capable of precipitating glycoprotein C and its precursor, whereas 3 clones, HD1, HD2 and HD3, produced antibody capable of precipitating glycoprotein D and its precursor. Antibody produced by the HC1 and HC2 clones neutralized HSV type 1 but not HSV type 2 or HSV type 1 strain MP, which lacks glycoprotein C. Antibody produced by the HD1 and HD2 clones neutralized both HSV type 1 and HSV type 2, whereas antibody produced by the HD3 clone neutralized HSV type 1 but not HSV type 2. The 2 clones which produced antibody to glycoprotein C and the 2 clones which produced type-common antibody to glycoprotein D were independently derived and not clonally related inasmuch as the antibody in each pair belonged to a different subclass of immunoglobulin.
