Abstract :

The antigen (s) recognized by the EIV-E12 monoclonal antibody (mAb) is first detected in the embryonic bursal mesenchyme on the precursor to the bursal secretory dendritic cell. Later in bursal embryonic development the prebursal stem cells which enter the developing follicle express the antigen recognized by mAb EIV-E12. The goal of this project is to characterize the antigen recognized by mAb EIVE12. In western blotting the deglycosylated bursal proteins showed reduced reactivity to mAb EIV-E12, indicating, that the EIV-E12 epitope of the antigen may consist of a carbohydrate group that is common to chicken B-cells. The EIV-E12 positive antigen is expressed by the plasma cells of terminal maturation of Bcells unlike the B-cell specific chB6 antigen. These differences in the expression patterns of EIV-E12 and chB6 positive antigens are confirmed by their different molecular weights of 200 and 65 kDa, respectively.
