Isolation of the major herpes simplex virus type 1 (HSV-1)-specific glycoprotein by hydroxylapatite chromatography and its use in enzyme-linked immunosorbent assay for titration of human HSV-1-specific antibodies.
A 131,000 molecular weight herpes simplex virus type 1 (HSV-1) glycoprotein designated antigen number 6 (Ag-6) was previously shown to possess almost exclusively HSV-1-specific antigenic sites. Fused rocket and crossed immunoelectrophoresis of fractions obtained from hydroxylapatite chromatography of crude HSV-1 antigen (Triton X-100-solubilized, infected tissue culture cells) showed that a subfraction of Ag-6 could be separated from the other HSV antigens. Enzyme-linked immunosorbent assay with the isolated Ag-6 showed that sera from rabbits infected with HSV-1 and HSV-1 human antisera contained antibodies to Ag-6, whereas sera from HSV-2-infected rabbits and sera from patients with primary HSV-2 infections did not react with Ag-6. Enzyme-linked immunosorbent assay of 852 human sera for antibodies to HSV type-common glycoproteins, Ag-6, and HSV 2-specific antigens showed that 139 sera which reacted negatively with HSV type-common glycoproteins also did not react with Ag-6 with HSV-2 specific antigens. The 713 sera reacting positively to HSV type-common antigens either reacted with Ag-6 (328 sera) or with HSV-2-specific antigens (31 sera) or both  (354 sera). This means that Ag-6 might be useful in large-scale human serology for the detection of past infection with HSV-1, irrespective of whether or not past infection with HSV-2 has occurred.
