Type-specific antigens for herpes simplex virus type 1 and 2 were prepared by rigorous absorption of cell extracts with heterotypic immune sera. Type-specificity was demonstrated by immunodiffusion and complement-fixation tests against immune sera prepared in rabbits. Specific type 1 complement-fixing reactivity was detected in eleven of fifteen sera from Roman Catholic nuns and in two convalescent sera from patients with recurrent herpes labialis; these sera had been previously shown to contain neutralising and complement-fixing antibody to herpes simplex virus. Three of the non-reacting sera contained low or absent levels of type-common complement-fixing reactivity and other contained no type-specific neutralising antibody. With the exception of three "acute" sera, specific type 2 complement-fixing reactivity was detected in every convalescent or interim serum obtained from patients with a virologically-proven history of type 2 herpes virus infection. It is suggested that complement-fixation testing using these absorbed type-specific antigens preparations may provide a convenient and rapid method for the identification of type-specific antibody in human sera.
Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
