PRODUCING RECOMBINANT PROTEINS WITH REDUCED LEVELS OF HOST CELL PROTEINS

Processes for producing recombinant proteins having low levels of residual host cell proteins. The processes comprise utilizing engineered host cell lines in which specific host cell proteins are tagged with purification tags, wherein the purification tags can be used to remove those specific host c...
