ULTRAPURIFIED DSBA AND DSBC AND METHODS OF MAKING AND USING THE SAME

摘要

The present invention provides methods for producing disulfide oxidoreductase A (DsbA) and disulfide oxidoreductase C (DsbC) polypeptides at very high levels of purity. Also provided are ultrapure DsbA and DsbC and methods of using same,e.g.,for use in immunoassays to show removal of DsbA and DsbC from biologics produced in bacteria.
