High-Throughput Expression in Microplate Format in Saccharomyces cerevisiae

We have developed a high-throughput technology that allows parallel expression, purification, and analysis of large numbers of cloned cDNAs in the yeast Saccharomyces cerevisiae . The technology is based on a vector for intracellular protein expression under control of the inducible CUP 1 promoter, where the gene products are fused to specific peptide sequences. These N-terminal and C-terminal epitope tags allow the immunological identification and purification of the gene products independent of the protein produced. By introducing the method of recombinational cloning we avoid time-consuming re-cloning steps and enable the easy switching between different expression vectors and host systems.
