通过活性染料标记溶壁微球菌做为基质,测定生物体液中微量溶菌酶。本比色法除回收率稍高外,操作简便、重现性良好、灵敏度高,可直接应用于未浓缩处理的低溶菌酶含量标本的测定,可以考虑推广应用。 Microbial lysozyme was measured in living body fluid by using reactive dye-labeled Microcystis as substrate. The colorimetric method has the advantages of simple operation, good reproducibility and high sensitivity, and can be directly applied to the determination of low lysozyme content samples which have not been concentrated and can be popularized and applied.
