Examples of Proteins Expressed Using the Brevibacillus Expression System II

High expression levels have been achieved for a variety of proteins (enzymes, antigens, and cytokines) regardless of their genetic origin (bacterial, archaeal, or eukaryotic).
Because secreted eukaryotic proteins often depend on intact disulfide bonds for activity, it is generally difficult to produce active proteins using typical prokaryote-based expression systems.
However, due to the secretory advantages of the Brevibacillus Expression System II, high expression levels of active recombinant proteins are possible even for proteins with extensive disulfide bonds.
