title: Monoclonal antibodies reacting with isotypic and/or allotypic determinants of human IgG.
abstract: Mice were immunized with purified human IgG myeloma proteins and hybridomas were prepared using their spleen cells. 1817 of the hybridomas secreted anti-Ig antibodies. Several of them detected subclass-associated determinants. Eight different specificities could be distinguished. The number of hybridomas in each category were the following: 3 anti-IgG1 (1.8% of all anti-Ig clones) 5 anti-IgG2 (0.3% of all anti-Ig clones) 2 anti-IgG3 (2.5% of all anti-Ig clones) 3 anti-IgG4 (12% of all anti-Ig clones) 12 anti-IgG1, IgG2, IgG3 70 anti-IgG1, IgG2, IgG4 2 anti-IgG2, IgG4 7 anti-IgG2, IgG4 (one out of five myelomas).
