| 摘要 |
The invention provides a synthesis-inducible eucaryotic promoter having a transcriptional activity comprising, for example, a heavy metal-sensitive DNA sequence, derived from a natural promotor, of a base sequence of any one of SEQ ID NOS: 1 to 4; an inducer of the transcriptional activation activity thereof; a recombinant expression vector comprising a site for the insertion of an extraneous gene ligated to the above promotor: a eucaryotic expression kit comprising eucaryotic cells transfected with the above vector and the above inducer; and a method for expression of an extraneous gene in a eucaryotic system by using the same
