TetraGenetics has developed TetraExpress™ for high-yield production of recombinant human ion channels to enable both biologics discovery and structure-based design of small molecules. TetraExpress™ is built on the properties of the protisit Tetrahymena thermophila and its unique ability to produce unprecedented levels of correctly folded and functional recombinant ion channels. TetraGenetics is leveraging its unique position to enable both large and small molecule drug discovery for these historically intractable targets.
