简要概述

钙离子荧光探针Fluo-8H, AM是美国AAT Bioquest生产的用于标记钙离子的荧光探针，钙的测量对于许多生物学研究至关重要。荧光探针显示结合Ca²⁺后的光谱响应，使研究人员能够通过荧光显微镜，流式细胞仪，荧光光谱和荧光酶标仪研究细胞内游离Ca²⁺浓度的变化。Fluo-3和Fluo-4最常用于可见光可兴奋的钙指示剂中。然而，Fluo-3 AM和Fluo-4 AM在酯酶水解后仅在活细胞中发生中度荧光，并且需要苛刻的细胞负载条件以最大化其细胞钙响应。Fluo-8®染料的开发是为了改善细胞负载和钙响应，同时保持方便的Fluo-3和Fluo-4光谱波长，最大激发波长为~490 nm，最大发射波长为~520 nm。Fluo-8®AM仅需要室温，而Fluo-3 AM和Fluo-4 AM需要37℃的细胞负载。此外，Fluo-8®比Fluo-4 AM亮2倍，比Fluo-3 AM亮4倍。AAT Bioquest提供一系列具有不同钙结合亲和力的优异Fluo-8®试剂（Fluo-8®：Kd = 389 nM; Fluo-8H：Kd = 232 nM; Fluo-8L：Kd =1.86μM; Fluo-8FF ：Kd =10μM）。我们还提供多种包装尺寸，以满足您的特殊需求，例如1毫克; 10×50μg; 20×50μg; HTS包装，无需额外包装费用。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-8H，AM原液。
2.1使用的Fluo-8H，AM的量：1毫克
2.2所需浓度：2 mM
2.3在合适的容器中，将1mg Fluo-8H TM，AM与465.12μL无水DMSO混合。
 

3.使用10μMFluo-8H ，AM 4在HHBS中制备2X工作溶液，0.08％Pluronic®F-127和2 mM丙磺舒。
3.1最终孔内浓度为Fluo-8H ，AM：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-8H TM，AM，25.6μL10％Pluronic F-127和256μL25mM丙磺舒。然后，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，我们建议使用Fluo-8H™的最终浓度，AM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以下：5μMFluo-8H ，AM，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 = 494/517 nm运行实验。
