Cell Counting Kit (CCK-8) CCK-8试剂盒
产品介绍
Cell Counting Kit-8简称CCK-8试剂盒,是一种基于WST-8(化学名:2-(2-甲氧基-4-硝苯基)-3-(4-硝苯基)-5-(2,4-二磺基苯)-2H-四唑单钠盐)的广泛应用于细胞增殖和细胞毒性的快速高灵敏度检测试剂盒。
WST-8属于MTT的升级产品,工作原理为:在电子耦合试剂存在的情况下,可以被线粒体内的脱氢酶还原生成高度水溶性的橙黄色的甲臜产物(formazan)。颜色的深浅与细胞的增殖成正比,与细胞毒性成反比。使用酶标仪在450nm波长处测定OD值,间接反映活细胞数量。
CCK-8法应用非常广泛,如药物筛选、细胞增殖测定、细胞毒性测定、肿瘤药敏试验以及生物因子的活性检测等。
产品特色
操作简单:产品本身是液体,即开即用;甲臜产物是水溶性的,不需要用有机溶剂溶解。
灵敏度高:线性范围广,灵敏度高,重复性好。
细胞毒性低:细胞毒性非常低,对后续实验没有影响。
稳定性好:培养液中酚红和血清的存在不会对检测造成影响。
应用性广:可用于大规模、高通量样品检测。
