Expression of soluble recombinant proteins in a cell-free system using a 96-well format.

For structural and functional genomics programs, new high-throughput methods to obtain well-expressing and highly soluble proteins are essential. Here, we describe a rapid procedure to express recombinant proteins in an Escherichia coli cell-free system using a 96-well format. The identification of soluble proteins is performed by the Dot Blot procedure using an anti-His tag antibody. The applications and the automation of this method are described.
