    摘要: The invention relates to vectors which include an inducible selection gene and a sequence which codes for a heterologous polypeptide. In a particular example the selection gene comprises the tet A and tet R genes. The vector may also include a sequence which is capable of conferring stability on the vector, such as the cer sequence, a transcription terminator, such as gene 32 from bacteriophage T4, a ribosome binding site, and a multi-cloning site. Hosts transformed with the vector, processes for preparing these hots, and processes for preparing polypeptides using these hosts.
