TrypZean® is recombinant bovine trypsin expressed in corn, available either as a lyophilized powder or in sterile solution. It is intended for use in animal cell culture. Because the recombinant protease is purified from a plant source, it can have none of the animal contaminants that could be present either in trypsin extracted and purified from animal pancreas, or recombinant trypsin produced in animal cells. The plant product origin also helps contain the cost of production.
