【摘要】 本文介绍超氧化物歧化酶（SOD）的氯甘脲和氯胺T标记方法的比较,结果表明:SOD用氯甘脲标记法¹³¹I标记率（55.34％）较同样条件下氯胺T标记法¹³¹I标记率（42.37％）为高;而且用氯甘脲标记方法的SOD酶的活性（0.5 U/μg）较氯胺T标记方法的SOD酶活性（0.2U/μg）要高。且前者具有操作简单、经济、高效、快速的优点。更多还原

【Abstract】 A comparison of radioiodine labelling methods of SOD with iodogen and chloramine T is reported. The result indicated that the radioiodine labelling rate for the former (55.34%) was higher than that for the latter (42.37%) at the same condition, and the enzyme activity for the former (0.5U/μg) was also higher than that for the latter (0.2U/μg). And the former is a simple, economic, efficient and speedy method.更多还原
