title: [Studies of the antibody heterogeneity in carp (Cyprinus carpio L.). I. Electrophoretic and isoelectric spectra of anti-DNP-antibodies].
abstract: Carp IgM as well as carp anti-DNP-antibodies migrate electrophoretically very well as a diffuse band into polyacrylamide gel of large pore size. The isoelectric spectra of the carp anti-DNP-antibodies are heterogeneous and show bands in the pI-range of 4.0 to 6.4. The activity of focused anti-DNP-antibodies could be demonstrated in the pI range between 5.4 to 6.4 even in high antibody dilutions. The investigated structural heterogeneity of the anti-DNP-antibodies of carp is a further proof for the phylogenetically early onset of a large antibody heterogeneity of lower vertebrates.
