title: A sandwich ELISA with monoclonal anti-IgG allotype antibodies permitting the deduction of the G1m genotype.
abstract: With murine monoclonal antibodies specific for the human IgG1 allotypes G1m(z), G1m(a), G1m(f) and the IgG1 subclass, sandwich enzyme-linked immunosorbent assays (ELISAs) were developed to determine whether different allotypic determinants are located on the same molecule. With the conventional haemagglutination-inhibition test, it is only possible to determine the phenotype. With this ELISA system, it is now possible to deduce the G1m genotype.
