Abstract
The present invention is directed to the cells, compositions and methods for the production of recombinant protein. In particular, the invention is directed to a production process for obtaining high levels of soluble recombinant CRMprotein from. Cells preferably contain one or more mutations of disulfide reductase genes, so that disulfide reductase activity is reduced. The invention also relates to purification method for CRMas well as characterization of properly folded CRMprotein.
