A tricistronic vector (i.e., a vector capable of expressing three exogenous genes, which are not fused together, under the control of one promoter) effectively can encode an immunoglobulin-presenting polypeptide and two immunoglobulin (Ig) polypeptides. The encoded Ig-presenting polypeptide is able to associate with at least one of the Ig polypeptides via co-expressed associating agents. A vector according to the present invention particularly is suited for phage display technology, e.g., when the Ig-presenting polypeptide is a phage coat protein and the Ig polypeptides associate to form a Fab. |
