Cloning and characterization of a high-copy-number novel insertion sequence from chemolithotrophic Thiobacillus ferrooxidans.

abstract：:A set of low copy number plasmid vectors for mammalian gene expression has been constructed. These vectors are derived from the previously described bacterial low copy number expression vectors, pWSK29 and pWKS30, which are present at six to eight copies per cell. The new plasmids also have the following useful proper...
