USE OF A ZWITTERIONIC DETERGENT/SURFACTANT FOR PURIFYING GLUTAMIC ACID DECARBOXYLASE (GAD) AND A COMPOSITION CONTAINING GAD

摘要

The extraction and purification of glutamic acid decarboxylase is improved by using buffer solutions containing zwitterionic detergents/surfactants preferably according to the following chemical formula: CyH2y+1 - N<+>(CH3)2 - CxH2x - SO3<-> wherein x is an integer from 1 to 5 and y is an integer from 2 to 20.
