摘要：A stabilized urease solution is formulated by blending water, buffering agents, abacteriostat, chelating agent, polyhydroxy organic compound and urease. The preferredbuffering agents are selected from low- conductivity zwitterionic buffer salts, such as N-2-hydroxyethyl- piperazine-N'-2-ethanesulfonic acid, triethanolamine, tris(hydroxymethyl)aminomethane, diethanolamine, aminomethyl propanol and mixtures thereof.
