Metal Fluor Zn-520是美国AAT Bioquest生产的 用于检测突触囊泡中存在的较高锌离子浓度的锌离子探针,并响应电刺激或兴奋毒性激动剂(0.05-50μM)释放,干扰钙敏感性小。 Metal Fluor Zn-520在结合锌离子(> 250倍)后显示出很强的荧光增强作用。 该细胞渗透性AM-酯可用于检测细胞内锌离子水平。百萤生物是AAT Bioquest的中国代理商,为您提供优质的锌离子探针Zn Metal Fluor 520, AM。
操作步骤
1.准备HHBS缓冲液
2.在高质量无水DMSO中制备2 mM至5 mM Metal Fluor Zn-520,AM原液
2.1使用的金属Fluor Zn-520,AM的量:1毫克
2.2所需浓度:2 mM
2.3在合适的容器中,混合1mg的Metal Fluor TM Zn-520,AM和692.89μL的无水DMSO。
3.使用10μM金属Fluor Zn-520,AM 2在HHBS中制备2X工作溶液
3.1终孔内浓度为Metal Fluor™Zn-520,AM:5μM
3.2在合适的容器中混合16μL的Metal Fluor Zn-520,AM。接下来,添加HHBS或您选择的缓冲液,
注意:对于大多数细胞系,我们建议使用Metal Fluor Zn-520,AM的终浓度为4至5μM。
4.将100μL染料工作溶液加入已经含有100μL培养基的所需孔中
4.1该步骤将染料工作溶液从2X稀释至1X,并将每种组分的终浓度调节至以下:5μM的Metal Fluor Zn-520,AM
5.孵育染料
5.1将染料加载板在细胞培养箱中孵育30-60分钟。
5.2将染料加载板在室温下孵育30分钟。
6.准备HHBS缓冲液(或您选择的缓冲液)。
6.1在合适的容器中加入HHBS或您选择的缓冲液,直至体积为4 mL。
7.用HHBS缓冲液或您选择的缓冲液替换染料工作溶液,使用1.0 mM Probenecid。
7.1首先,从所需孔中除去200μL染料工作溶液和培养基。
7.2在相同的孔中加入200μL含有1.0mM丙磺舒的HHBS(或您选择的缓冲液)。
8.运行实验
8.1为您的样品添加所需的处理。
8.2以Ex / Em = 492/514 nm运行实验。
