Escherichia coli is one of the most widely used hosts for the production of heterologous proteins and its genetics are far better characterized than those of any other microorganism. The E. coli expression system is regarded as the most commonly used, economical, and classical expression system because of its simple structure, clear genetic background, high yield of target protein, and its short culture period. In recent decades, E. coli expression system has also been developed and improved continuously, and been used intensively by scientific researchers and industrial users for a large number of recombinant protein expression. The system is mainly used for antigen preparation, ligand preparation, and expression of cytokines and bacteria (Staphylococcus aureus, Escherichia coli, etc.) proteins services.
Abvigen has extensive experience and be very professional in E. coli protein expression and purification. We can solve various difficult problems during the protein expression and purification process. We have successfully developed many proteins expressed in E. coli, which contain proteins with high purity.
