Trypsin for General Research Applications

For the many uses of this protease, we offer trypsins from bovine, porcine, and human pancreas. Products vary in specific activity and purity, so that researchers can choose the product best suited to their needs, which may range from protein sequencing to immunohistochemistry. Most activities are expressed as BAEE (Na-benzolyl-L-arginine ethyl ester) units. Several products have been treated to essentially eliminate chymotryptic activity, for applications that require cleavage only at arginine or lysine residues. For procedures where several proteolytic activities can be helpful, as in cell culture, elastase and chymotrypsin are present. All products in this group are sold as dry powders; some are salt-free, some have been dialyzed into lactose before lyophilization, one is an ethanol precipitate and one has been prepared by crystallization. Researchers can thus choose the method of preparation best suited for their own application.
