| Abstract: | Monoclonal antibodies can be used in sandwich enzyme-linked immunosorbent assays to measure viral antigens. Such an assay was developed to detect the core protein, p24, of human T-cell lymphotropic virus type III and lymphadenopathy-associated virus, etiologic agents of the acquired immunodeficiency syndrome (AIDS). Another AIDS-associated virus, AIDS-associated retrovirus type 2 (ARV-2) could not be detected in this assay because of the low affinity of one of the monoclonal antibodies to ARV-2 p24. Detection of ARV-2 was accomplished with a monoclonal antibody-rabbit polyclonal antibody sandwich enzyme-linked immunosorbent assay. These two assays were used to efficiently detect AIDS-related viruses in lymphocyte cell cultures and to distinguish strains of the viruses. |
