单位定义
一个单位定义为在1X T4多核苷酸激酶反应缓冲液中,37℃下30分钟内催化掺入1 nmol [ 32 P](ATP供体)的酶量。
质量控制分析
单位表征测定
单位活性使用2倍系列稀释法测量。在1X反应缓冲液中制备酶的稀释液,并将其加入到50μL含有10μMOligo dT单链DNA,1X PNK反应缓冲液和66μMATP的反应中,并将[γ- 32 P] ATP反应在37°孵育30分钟将其置于冰上,并使用Sambrook和Russell的方法(Molecular Cloning,v3,2001,pp.A8.25-A8.26)进行分析。
蛋白质浓度(OD 280)测量使用使用2.0mg / ml BSA样品(Pierce Cat#23209)标准化的Nanodrop ND-1000分光光度计
在OD 280处分析2.0μL酶样品并用产品储存溶液冲切。使用消光系数63,440和分子量34,620道尔顿将观察到的3个重复样品的平均测量结果转换为mg / mL。
SDS-Page(物理纯度评估)
将2.0μL酶溶液加载到变性的4-20%Tris-甘氨酸SDS-PAGE凝胶上,其侧翼为宽范围MW标记和2.0μL1:100稀释的样品。电泳后,将凝胶染色并比较样品以确定物理纯度。该测试的验收标准要求浓缩样品中污染带的总量不超过稀释样品中目的蛋白质条带的质量,确认浓缩样品的纯度大于99%。
