产品介绍
钙离子荧光探针Fluo-5N,AM是美国AAT Bioquest生产的钙离子荧光探针,Fluo-5N是Fluo-4的类似物,具有较低的钙结合亲和力(Kd = ~90 uM),使其适用于检测1μM至1 mM范围内的细胞内钙水平,这将使Fluo-4的反应饱和。。 通过将溶解的指示剂直接加入含有培养细胞的培养皿中,可以将Fluo-5N AM酯直接加载到活细胞中。 它与氩离子激光源在488 nm激发相容,使Fluo-5N可用于共聚焦显微镜,流式细胞仪和微孔板筛选应用。 它的激发和发射波长分别为494和516 nm。 钙结合后,其荧光强度增加> 100倍。金畔生物是AAT Bioquest 的中国代理商,为您提供最优质的钙离子荧光探针。

产品说明书
操作步骤
1.准备HHBS缓冲液,10%Pluronic®F-127溶液和25 mM Probenecid溶液。
2.在高质量无水DMSO中制备2 mM至5 mM Fluo-5N,AM *细胞渗透物*储备溶液。
2.1使用的Fluo-5N,AM *细胞渗透物*的量:1mg
2.2所需浓度:2 mM
2.3在合适的容器中,将1mg Fluo-5N,AM *细胞渗透物*与443.29μL无水DMSO混合。
3.使用10μMFluo-5N,AM *细胞渗透物* 4在HHBS中制备2X工作溶液,0.08%Pluronic®F-127和2 mM丙磺舒。
3.1最终井内浓度的Fluo-5N,AM *细胞渗透物*:5μM
3.2Pluronic®F-127的最终井内浓度:0.04%
3.3最终孔内浓度的丙磺舒:1mM
3.4在合适的容器中混合16μLFluo-5N,AM *细胞渗透物*,25.6μL10%Pluronic®F-127和256μL25mM丙磺舒。接下来,添加HHBS或您选择的缓冲液,直到体积为3.2 mL。
注意:对于大多数细胞系,我们建议最终浓度为Fluo-5N,AM *细胞渗透物*为4至5μM。
注意:推荐的Pluronic F-127井浓度最终为0.02%至0.04%。
注意:推荐的最终浓度为1至2.5 mM的Probenecid。
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,并将每种组分的最终浓度调节至:5μMFluo-5N,AM *细胞渗透物*,0.04%Pluronic F-127,1mM丙磺舒。
5.孵育染料
5.1将染料加载板在细胞培养箱中孵育20-120分钟。
5.2将染料加载板在室温下孵育30分钟。
6.用1.0 mM Probenecid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160μL的25mM丙磺舒。 接下来,添加HHBS或您选择的缓冲液,直到体积为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 = 494/516 nm运行实验
