????? 超氧化物歧化酶對機體的氧化與抗氧化平衡起著至關重要的作用。此酶能清除超氧陰離子自由基,保護細胞免受損傷,本試劑盒采用黃嘌呤氧化酶法(羥胺法)測定SOD活力??蓽y血清(漿)、腦脊液、胸水、腹水、腎透析液、尿液、精液、紅細胞、白細胞、血小板、心肌培養細胞、腫瘤培養細胞、各種動植物組織細胞、及亞細胞水平(線粒體、微粒體)中的SOD活力,并可檢測微生物、藥物、食品、飲料、化妝品中的SOD活力。
產品優點如下:
1、快速簡便:全程約50分鐘,可測100例左右樣本。
2、取樣量微:本法取手指或耳垂等末梢血20ul~50ul即可測紅細胞中的SOD,只需2ml靜脈血可測白細胞中的SOD及血小板中SOD,只需50mg左右組織就可測組織勻漿、胞漿中的SOD,0.2g組織可測線粒體及微粒體中的SOD。
3、靈敏度高:IC50=0.05g/ml,是鄰苯三酚法的18倍。
4、穩定性好:試劑盒2~8℃存放6個月有效。
5、再現性好:變異系數CV=1.7%。
6、回收試驗: X =103.3%。
7、受外界影響因素?。焊蓴_因素少,重復性強。
8、測試面廣:可測動物血液、組織、各種體液、灌流液等、各種培養細胞、細菌、植物組織、各種水產以及化妝品、保健品等,效果均佳。
