AMPLIFYING THE EXPRESSION OF RECOMBINANT DNA PRODUCTS

摘要

Amplified expression of recombinant DNA products is achieved in hosts expressing protease that cleave at multi-basic amino acid residues. To this end, wild-type genes encoding the desired protein products are mutated by substituting codons or eliminating codons encoding multi-basic amino acid residues while maintaining the activity of the expressed protein product. Mutation of the desired gene can be conveniently carried out by site-specific in vitro mutagenisis.
