DNASE I,LYO., 100 MG

产品描述 General description 牛胰腺脱氧核糖核酸酶I(DNase I)是DNA小沟相互作用的核酸酶,具有相对较低的特异性。该蛋白质由两个中心β 折叠构成,而每个折叠由六个β-链所组成。该结构被大量的环以及α-螺旋区域包围。该酶与核酸外切酶III具有结构相似性。DNase I是研究得最透彻的哺乳动物来源的内切酶之一。 Application 在组织解离过程中,部分细胞被裂解并导致DNA的释放。单分子DNA可能会导致细胞结团。向解离缓冲液中加入DNase I会导致该细胞外DNA的降解,因而避免了因意外结团造成的细胞损失。 Unit Definition 一个单位表示在测定条件下导致吸光度以0.001每分钟的速率而增加的酶活力。 Preparation Note 激活剂:二价金属离子 (Ca2+, Mg2+) 工作浓度:0.01 至 1 mg/ml 注意:必须针对每种细胞类型单独确定工作浓度。为实现最佳活性,酶须添加 5 mM Mg2+。 Reconstitution 用无菌的双蒸水对冻干酶进行重悬(10 mg/ml);用PBS(磷酸盐缓冲液)、HBSS(Hank′s 平衡盐溶液)或培养基进行进一步的稀释。 Other Notes 仅用于生命科学研究。不可用于诊断。
