摘要： A eukaryotic expression vector capable of displaying a multi-chain polypeptide on the surface of a host cell is provided, such that the biological activity the multi-chain polypeptide is exhibited at the surface of the host cell. Such a vector allows for the display of complex biologically active polypeptides, e.g., biologically active multi-chain polypeptides such as immunoglobulin Fab fragments. The present invention describes and enables the successful display of a multi-chain polypeptide on the surface of a eukaryotic host cell. Preferred vectors are described for expressing the chains of a multi-chain polypeptide in a host cell separately and independently (e.g., under separate vector control elements, and/or on separate expression vectors, thus forming a matched vector set). The use of such matched vector sets provides flexibility and versatility in the generation of eukaryotic display libraries, for example the ability to generate and to display multi-chain polypeptides by combining and recombining vectors that express variegations of the individual chains of a multi-chain polypeptide. Entire repertoires of novel chain combinations can be devised using such vector sets.
