title: Monoclonal antibodies against heavy and light chains of domestic mink IgG.
abstract: A panel of 26 monoclonal antibodies (MAbs) specific to mink IgG was produced and analyzed by ELISA, immunodiffusion assay (IDA) and immunoblotting assay. All the raised MAbs were directed against the isotypic IgG epitopes. Immunoblotting assay demonstrated that 11 MAbs reacted only with the Fc-fragments of IgG and 7 only with the light chains. Four antibodies bound to the Fab-containing fragments and failed to react with the Fc-fragments or isolated L-chains. Three MAbs did not react with IgG in IDA. Based on the results of IDA and cross-blocking assays, the MAbs were divided into 10 groups, with the MAbs of each group recognizing the same epitope. In IDA some MAbs were able to react with the epitopes which are common to the IgGs of some other representatives of Mustelidae family and also to some mammalian species remote from mink (dog, horse, pig, fox and rabbit).
