产品介绍

新型钙离子荧光探针Calbryte 590,钾盐是美国AAT Bioquest生产的钙离子荧光探针,细胞内钙通量测定法是监测信号转导途径和G蛋白偶联受体(GPCR)和钙通道靶标的高通量筛选的一种广泛使用的方法。随后在1989年推出Rhod-2,后来开发了具有改善的信噪比的Rhod-4和Cal-590,它们成为用于共聚焦显微镜,流式细胞术和高通量筛选应用的广泛使用的红色荧光Ca2 +指示剂。Calbryte 590是用于测量细胞内钙的新一代红色荧光指示剂。Calbryte 590的信号/背景比率和细胞内保留特性大大提高,使其成为评估GPCR和钙通道靶标以及在活细胞中筛选其激动剂和拮抗剂的最强大的红色荧光指示剂。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的新型钙离子荧光探针Calbryte 590,钾盐。

产品介绍

新型钙离子荧光探针Calbryte-520XL AM是美国AAT Bioquest生产的钙离子荧光探针,Calbryte 520XL,AM是一种具有极低亲和力的新型荧光且可渗透细胞的钙指示剂。像其他染料AM细胞加载一样,Calbryte 520XL AM酯不发荧光,一旦进入细胞内部,它就会被细胞内酯酶水解并被激活。激活的指示剂是一种极性分子,不再能够自由扩散通过细胞膜,基本上被困在细胞内部。Calbryte 520XL对钙离子的亲和力低,Kd约为300 uM,这与众所周知的Rhod 5N相似,但比Rhod-5N稳定得多。Calbryte 520XL在高浓度钙离子存在下产生明亮的荧光信号。它具有与Fluo-4相同的激发和发射波长,因此相同的Fluo-4测定设置可轻松应用于基于Calbryte 520XL的钙测定。Calbryte 520XL是Rhod-5N的绝佳替代品。我们还提供Calbryte 520XL,钾盐(#20645),Calbryte 520XL-右旋糖酐(#20648),Calbryte 520XL叠氮化物(#20643),它们可以通过众所周知的点击化学轻松地偶联到载体上。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的新型钙离子荧光探针Calbryte-520XL AM。

产品介绍

新型钙离子荧光探针Calbryte 630,钾盐是美国AAT Bioquest生产的钙离子荧光探针,钙测量对于许多生物学研究至关重要。显示结合钙后光谱响应的荧光探针使研究人员能够使用荧光显微镜,流式细胞仪,荧光光谱和荧光酶标仪来研究细胞内游离钙浓度的变化。x-Rhod-1通常用作红色荧光钙指示剂。但是,x-Rhod-1在酯酶水解后在活细胞中仅适度发荧光,并且细胞钙反应非常小。Calbryte 630的开发旨在改善x-Rhod-1的细胞负载和钙反应,同时保持x-Rhod-1的光谱波长,使其与TexasRed®滤光片兼容。在CHO和HEK细胞中,Cal-630 AM的细胞钙反应比x-Rhod-1敏感得多。Calbryte 630的光谱与FITC,AlexaFluor®488和GFP的光谱完全分离,使其成为与GFP细胞系或FITC / AlexaFluor®488标记的抗体进行细胞内分析多重检测的理想钙探针。Calbryte 630是用于测量细胞内钙的新一代红色荧光指示剂。Calbryte 630 AM的信号/背景比和细胞内保留特性大大提高,使其成为评估GPCR和钙通道靶标以及在活细胞中筛选其激动剂和拮抗剂的最强大的深红色荧光指示剂。像其他染料AM细胞上样一样,Calbryte 630 AM酯是非荧光的,一旦进入细胞内部,它就会被细胞内酯酶水解并被激活。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的新型钙离子荧光探针Calbryte 630,钾盐。

简要概述

新型钙离子荧光探针Cal-520 AM是美国AAT Bioquest生产的钙离子荧光探针,Calbryte 520,Calbryte 590和Calbryte 630提供最强大的均匀荧光测定工具,用于检测细胞内钙动员。与现有的钙指示剂(如Fluo-3 AM,Fluo-4 AM和Rhod-2 AM)相比,这些钙敏感染料明显更亮,并提供更高的信噪比,大大提高了细胞内保留和负载效率。表达通过钙发出信号的GPCR或钙通道的细胞可以预装载可以穿过细胞膜的Calbryte 520 AM,Calbryte 590 AM或Calbryte 630 AM。一旦进入细胞内,Cal520 AM,Calbryte 590 AM或Calbryte 630 AM的亲脂性阻断AM基团被细胞内酯酶切割,产生带负电荷的荧光Calbryte 染料,留在细胞内。它们与钙结合后的荧光大大增强。当用激动剂刺激细胞时,该受体表示细胞内钙的释放,这显着增加了Calbryte 520,Calbryte 590或Calbryte 630的荧光。高灵敏度和> 100倍荧光增强的特性使Calbryte 520 AM, Calbryte 590 AM或Calbryte 630 AM是测量细胞内钙的最强大指标。

除了方便的激发波长和钙的大荧光增强外,Calbryte 520,Calbryte 590和Calbryte 630主要定位于细胞溶胶中,不像Rhod-2主要位于线粒体中。 此外,Calbryte 590和Calbryte 630的长Ex / Em波长使这些染料成为完美的钙指示剂,可与绿色荧光蛋白(GFP)细胞系进行多色检测。 此外,Calbryte 520,Calbryte 590或Calbryte 630钙测定经过优化,可与大多数现有荧光仪器兼容。 Calbryte 520可在488 nm处激发,并与FITC滤光片组配合使用。 Calbryte 590经过优化,可在555 nm激发,并与TRITC / Cy3滤光片组配合使用。 Calbryte 630经过优化,可在594 nm激发,并与TexasRed®滤光片组配合使用。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

使用Calbryte 520 AM,Calbryte 590 AM或Calbryte 630 AM酯类

1.操作步骤

        Calbryte AM酯应在使用前在无水DMSO中重新配制。 DMSO储备溶液可以在-20℃下储存(干燥)并避光。 在这些条件下,AM酯应稳定三个月。 以下是我们推荐的将Calbryte 520 AM,Calbryte 590 AM或Calbryte 630 AM酯加入活细胞的方案。 该方案仅提供指南,实际应根据您的特定需求进行修改。

a)在无水DMSO中制备2至5mM Calbryte 520AM,Calbryte 590AM或Calbryte 630AM酯的储备溶液。

b)将Calbryte 520 AM,Calbryte 590 AM或Calbryte 630 AM溶解在DMSO中或将等份的指示剂储备溶液解冻至室温。 在Hanks和Hepes缓冲液(HHBS)或您选择的缓冲液(0.04%Pluronic®F-127)中制备10至20μM的染料工作溶液。 细胞加载所需指示剂的确切浓度必须根据经验确定。

注意:非离子型洗涤剂Pluronic®F-127有时用于增加Calbryte 520 AM,Calbryte 590 AM或Calbryte 630 AM酯的水溶性。 各种Pluronic®F-127可从金畔购买。

c)如果您的细胞(如CHO细胞)含有有机阴离子转运蛋白,可将丙磺舒(1-2 mM)添加到染料工作溶液中(最终浓度为0.5-1 mM)

注意:各种ReadiUse 丙磺舒(包括水溶性钠盐和稳定溶液)均可从金畔购买。

d)将等体积的染料工作溶液(来自步骤b或c)加入细胞板中。

e)将染料加载板在细胞培养箱中孵育约60分钟,然后将板在室温下再孵育15分钟。

f)用HHBS或您选择的含有阴离子转运蛋白抑制剂(如1 mM丙磺舒)的缓冲液替换染料工作溶液,以去除多余的探针。

g)对于Calbryte 520 AM,在Ex / Em = 490 / 525nm处进行钙测试,对于Calbryte 590 AM,使用540/590nm进行钙测试,对于Calbryte 630 AM,使用610/640nm进行钙测试。

图3. CHO-K细胞中内源性P2Y受体对ATP的反应。 在96孔黑壁/透明底板中,将CHO-K细胞以每100μL/孔40,000个细胞接种过夜。 将100μL具有2mM丙磺舒的HbBS中的Calbryte 590AM或Calbryte  630 AM加入孔中,并将细胞在37℃下孵育1小时。 将染料加载培养基替换为200μLHHBS,用50μL50μMATP处理,并使用TRITC通道(Calbryte  590)和Texas Red Channel(Calbryte 630)用荧光显微镜(Keyence)成像。

 

结论

        由于Ca 2+在生物学中的重要性,已经建立了许多用于分析细胞和/或亚细胞Ca 2+活性机制的技术/方法。 尽管用于分析Ca 2+活性的每种方法都具有优于其他方法的某些优点,但每种方法也存在缺点。 凭借上述出色的性能,我们相信Calbryte 520,Calbryte 590和Calbryte 630钙检测试剂为各种生物系统中的细胞内钙分析和监测提供了新的强大工具。

        正如可能预测的那样,Ca2 +分析中许多研究人员的兴趣从细胞水平转移到亚细胞水平。 已经发现Ca2 +在整个细胞中均匀分布,并且在多种细胞(例如,卵母细胞,心肌细胞,肝细胞和外分泌细胞)中观察到Ca2 +的细胞内异质性(例如Ca2+ waves and Ca2+ sparks)。 随着20世纪80年代共聚焦激光扫描显微镜(CLSM)和2000年代先进的酶标仪(如FLIPR,FDSS和NOVOStar专用于细胞内Ca2 +检测)的出现,细胞内Ca2 +的测量显着加速。 共聚焦激光扫描显微镜和最近的多光子显微镜除了测量其浓度外,还允许在亚细胞水平上对细胞内Ca 2+信号传导进行精确的空间和时间分析。
