超氧化物歧化酶对机体的氧化与抗氧化平衡起着至关重要的作用。此酶能清除超氧阴离子自由基，保护细胞免受损伤，本试剂盒采用WST-1法测定SOD活力。可测血清(浆)、脑脊液、胸水、腹水、肾透析液、尿液、精液、红细胞、白细胞、血小板、心肌培养细胞、肿瘤培养细胞、各种动植物组织细胞、及亚细胞水平(线粒体、微粒体)中的SOD活力，并可检测微生物、药物、食品、饮料、化妆品中的SOD活力。
产品优点如下：
1、快速简便：双试剂，96孔板直接操作，快速、简便。
2、取样量微：需要的样本量是羟胺法的1/10。
3、灵敏度高：检测线0.5U/ml，是羟胺法5倍，邻苯三酚法的200倍
4、稳定性好：批内CV=5.50%,批间CV=3.32%，试剂盒2～8℃存放3个月有效。
5、再现性好：变异系数CV=1.2%。
6、回收试验： X =102.3%。
7、受外界影响因素小：干扰因素少，重复性强。且特异性强，不受类SOD物质的干扰
8、测试面广：可测动物血液、组织、各种体液、灌流液等、各种培养细胞、细菌、植物组织、各种水产以及化妆品、保健品等，效果均佳。
