[An improved method of determining the carbonic anhydrase activity of erythrocytes]

The article describes a method of determining erythrocytic carbonic anhydrase activity based on measuring medium pH which characterizes the rate of the carbon dioxide hydration in the borate buffer under the effect of enzyme. The use of modern measuring technique makes it possible to rapidly obtain the results of high precision. The normal activity of the erythrocytic carbonic anhydrase of the capillary blood considerably exceeds that of the enzyme in the vascular bed.
