Enzymatic Tools for Protein Processing and Analysis

ProteoSure™ family enzymes and proteins are genetically engineered and expressed in E.coli. They are purified via our proprietary ProteoSure™ purification process for the highest specific enzymatic activities. Unlike other commercial enzymes that are derived from an animal source via lengthy extraction and purification process, our ProteoSure™ proteins contain no animal derived impurities and retain their full enzymatic potency. The animal-free recombinant proteins are suitable for a broad range of protein processing and analysis applications. Explore our recombinant enzymatic tools:
