ABSTRACT:
The present invention relates to a method for the manufacture and purification of recombinant trypsinogen and trypsin inE. coliand yeast, using high yield expression vectors with and without secretion leader sequences. The invention further relates to an improved method and apparatus for carrying out protein refolding specifically useful for processing trypsinogen that has accumulated intracellularly in the form of inclusion bodies.
