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,本试剂盒采用黄嘌呤氧化酶法(羟胺法)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:全程约50分钟,可测100例左右样本。
2、取样量微:本法取手指或耳垂等末梢血20ul~50ul即可测红细胞中的SOD,只需2ml静脉血可测白细胞中的SOD及血小板中SOD,只需50mg左右组织就可测组织匀浆、胞浆中的SOD,0.2g组织可测线粒体及微粒体中的SOD。
3、灵敏度高:IC50=0.05g/ml,是邻苯三酚法的18倍。
4、稳定性好:试剂盒2~8℃存放6个月有效。
5、再现性好:变异系数CV=1.7%。
6、回收试验: X =103.3%。
7、受外界影响因素小:干扰因素少,重复性强。
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。
