产品介绍

Oxonol V是一种敏感的慢响应膜电位探针,已广泛用于测量许多生物系统的膜电位。Oxonol V的荧光在膜超极化时降低。通常,慢响应探针在跨膜分布中表现出电位依赖性变化,并伴有荧光变化。它们的光学响应幅度远远大于快速响应探针(通常每mV荧光变化1%)。慢响应探针,包括阳离子碳花青素,若丹明和阴离子恶臭酚,适用于检测由呼吸活动,离子通道通透性,药物结合和其他因素引起的非兴奋性细胞的平均膜电位变化。

产品介绍

线粒体膜电位荧光探针10-壬基吖啶橙溴化物是美国AAT Bioquest生产的细胞膜电位荧光探针。10-壬基吖啶橙(NAO)是吖啶橙的衍生物, 是一种用于完整细胞内线粒体特异性荧光标记物。与Rh123相比,细胞中NAO的积聚与质子动力驱动关系不大,但是与线粒体相关膜蛋白或者脂类发生作用相关。NAO的摄入不依赖于线粒体跨膜电势差,可用于检测线粒体。NAO可与心磷脂等带负电荷磷脂特异性结合, 其与线粒体膜的相互作用不依赖于线粒体的膜电位; 分析细胞凋亡时, 可用罗丹明123来检测线粒体的膜电位, 而用NAO来检测线粒体结构的完整性。NAO和罗丹明123(Rh123)是研究线粒体功能一对好的染料。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的线粒体膜电位荧光探针10-壬基吖啶橙溴化物。

简要概述

我们的Cell Meter 检测试剂盒是一套用于检测细胞功能的工具。可以使用多种参数。该特定试剂盒旨在通过测量线粒体膜电位(MMP)的丢失来检测细胞凋亡。线粒体膜电位的凋亡与线粒体通透性过渡孔的开放相吻合,导致细胞色素C释放到细胞质中,进而触发凋亡级联反应中的其他下游事件。该荧光测定法使用我们专有的阳离子MitoLite Orange检测细胞中线粒体膜电位的变化。在正常细胞中,当线粒体中积累了MitoLite Orange时,橙色荧光强度会增加。但是,在凋亡细胞中,MMP凋亡后,MitoLite Orange的荧光强度降低。可以对用MitoLite Orange染色的细胞进行荧光检测。我们的Cell Meter 橙色线粒体膜电位测定试剂盒可通过优化的测定方法提供所有必需成分。该试剂盒可用于筛选凋亡激活剂和抑制剂。而且该测定可以以方便的96孔和384孔荧光酶标仪进行检测,而无需清洗步骤。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的Cell Meter 线粒体膜电位检测试剂盒。

产品说明书

样品实验方案

简要概述

  1. 准备细胞
  2. 添加测试化合物
  3. 添加MitoTell Orange工作溶液(100 µL /孔/ 96孔板或25 µL /孔/ 384孔板)
  4. 将板在5%CO2、37°C的培养箱中孵育15-30分钟
  5. 添加测定缓冲液B(50 µL /孔/ 96孔板或12.5 µL /孔/ 384孔板)
  6. 检测Ex / Em = 540/590 nm(截止= 570 nm)的荧光增加(底部读取模式)

 

溶液配制

工作溶液配制

将50 µL的200X MitoTell 橙色(组分A)添加到10 mL的测定缓冲液A(组分B)中,并充分混合以制成MitoTell Orange工作溶液,避光。

 

实验步骤

1.用测试化合物处理细胞一段时间,以诱导细胞凋亡,并建立平行对照实验。

阴性对照:仅用载体处理细胞。

阳性对照:在37°C 5%CO2培养箱中,以5-50 µM的浓度用FCCP或CCCP处理细胞15至30分钟。 注意:CCCP或FCCP可以与MitoTell Orange同时添加。 为了获得最佳结果,可能需要为每个单独的细胞系滴定CCCP或FCCP。

2.取出细胞培养基。注意:在添加MitoTell Orange工作溶液之前,必须除去细胞培养基。

3.将100 µL /孔/ 96孔板或25 µL /孔/ 384孔板的MitoTell Orange工作溶液添加到细胞板中。

4.将板在5%CO2、37°C​​的培养箱中避光放置15-30分钟。注意:适当的孵育时间取决于所用的单个细胞类型和细胞浓度。优化每个实验的孵育时间。

5.将50 µL /孔/ 96孔板或12.5 µL /孔/ 384孔板的测定缓冲液B(组分C)添加到细胞板中。注意:加载后请勿洗涤细胞。对于非贴壁细胞,建议在加入测定缓冲液B(组分C)后,以800 rpm离心细胞板2分钟,然后制动。

6.在加入分析缓冲液B(成分C)10至30分钟后,使用荧光酶标仪(底部读取模式)在Ex/Em=640/680 nm(截止=665 nm)处检测荧光强度,可以使用终点模式,也可以使用动力学模式。
