Takara Recombinant protein expression: Brevibacillus Expression System II

Overview

• Efficient production of secreted or intracellular recombinant target proteins
• Negligible amounts of extracellular protease; products remain intact in culture medium
• Unlike E. coli, no endotoxins
• Proteins are produced in active form
• Easy to culture, handle, and sterilize

Examples of proteins expressed using the Brevibacillus Expression System II

Examples of expressed proteins using the Brevibacillus Expression System II are shown in the table below. 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 protein are possible even for proteins with extensive disulfide bonds.
