Color selection with a hygromycin-resistance-based Escherichia coli-mycobacterial shuttle vector

Gene. 1995 Dec 1;166(1):181-2. doi: 10.1016/0378-1119(95)00597-x.


Hygromycin-resistance (HyR)-based Escherichia coli-mycobacterial shuttle plasmids have high efficiencies of transformation and a broad mycobacterial host range. We have introduced a lacZ alpha (encoding the alpha-polypeptide fragment of beta-galactosidase (beta Gal))-multiple cloning site cassette into a HyR-based shuttle vector to generate a plasmid with nine unique cloning sites and the added feature of beta Gal color selection in appropriate E. coli host strains.
