title: Studies on equine immunoglobulins. IV. Immunoglobulins of the  donkey.
abstract: Donkey IgGa was isolated in purified form from normal and immune donkey sera by column chromatography on DEAE-cellulose. Isolated donkey IgGa and mixtures of (IgGa+IgGb) were used as antigens to prepare rabbit reagents specific for equine IgGa or IgGb. Antibodies present in sera obtained from a single donkey at various times during the course of hyperimmunization with BSA were isolated by immuno-adsorption. The class or subclass of immunoglobulins present among isolated, donkey anti-BSA antibodies was determined by use of specific rabbit anti-equine immunoglobulin reagents. The homologues of horse IgGa, IgGb, IgGc and IgA were identified in normal donkey, mule, hinny and zebra serum.
