Abstract
Several methods for purification of thyroid protease have been investigated. Chromatography on diethylaminoethyl and carboxymethyl cellulose resulted in purification and separation of two distinct acidic proteases. One protease shewed a pH optimum of 3.8 and the other 5.7. A combination of chromatography on both types of cellulose columns resulted in 500 fold purification of both enzymes.Keywords
