The enzyme phosphoglycerate kinase (PGK) was immobilized in a variety of quaternary ammonium salt modified Nafion membranes in order to protect it from denaturization due to pH and/or temperature fluctuations. To compare the relative efficiency of the immobilized enzyme with the enzyme in solution, the enzymatic activity of the membranes consisting of the enzyme and salt modified Nafion was observed via UV/Vis spectrophotometry.
