title: Comparative studies on the structure of biliary immunoglobulins of some avian species. I. Physico-chemical properties of biliary immunoglobulins of chicken, turkey, duck and goose.
abstract: In pooled bile of chicken, turkey, duck and goose immunoglobulins (Igs)+ were found in relatively high amounts between 4.5 and 15.0 mg/ml (corresponding to 28 to 36% of the total protein contents). All biliary Ig fractions studied possess (H2L2)n structure estimated by SDS-PAGE. In chicken and turkey L chains are assumed to be non-covalently linked to the polymeric H chains. In duck and goose L chains are completely linked to H chains. The Mr of H chains are rather similar: 64 kDa for the Igs of chicken and turkey bile and 67 kDa for the biliary Igs of duck and goose. There are slight differences in the electrophoretic mobility: Chicken and turkey Igs are beta 1/alpha 2-globulins and the corresponding Ig fractions from duck and goose are beta 2-globulins.
