A paper describing ligation-independent cloning vectors constructed for high-throughput cloning and purification of proteins.
Fifteen related ligation-independent cloning vectors were constructed for high-throughput cloning and purification of proteins. The vectors encode a Tobacco Etch Virus (TEV) protease site for removal of tags that facilitate protein purification (His-tag) or improve solubility (MBP, GST). Specialized vectors allow coexpression and copurification of interacting proteins, or in vivo removal of MBP by Tobacco Vein Mottling Virus (TVMV) protease to improve screening and purification. All target genes and vectors are processed by the same protocols, which we describe here.
We developed a set of superior LIC vectors tailored specifically for automated purification of proteins for crystallization. Details of these vectors can be found at http://bioinformatics.anl.gov/mcsg/technologies/vectors.html. More information can be found in the 2011 review by Kim, et al.
