The methods of preparating immobilized lactate oxidase enzyme-membrane-ring and the properties of the rings are described in this paper . We believe that the rings are equivalent to the YSI enzyme-membrane-ring of U. S. A. and the former can forms a complete set with YSI-23L LACTATE .

本文研究了固定化L-乳酸氧化酶膜圈的制作技术及其生化特性，并与美国YSI酶膜圈进行了比较，认为二者具有等值性，可与YSI-23L型乳酸分析仪配套使用。
