产品详细介绍

简要概述

钙离子荧光探针Fluo-8L, 钠盐是美国AAT Bioquest生产的用于钙通量测定的试剂,钙测量对于许多生物学研究至关重要。在结合Ca2+后显示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Ca2+浓度的变化。在可见光激发钙指示剂中,Fluo-3和Fluo-4最常用。但是,Fluo-3 AM和Fluo-4 AM在酯酶水解后在活细胞中仅适度发荧光,并且需要苛刻的细胞加载条件才能最大化其细胞钙反应。开发Fluo-8®染料可改善细胞负载和钙响应,同时保持便捷的Fluo-3和Fluo-4光谱波长(在〜490 nm处具有最大激发和在〜520 nm处具有最大发射)。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®的亮度是Fluo-4 AM的2倍,是Fluo-3 AM的4倍。AAT Bioquest提供了一套出色的Fluo-8®试剂,具有不同的钙结合亲和力(Fluo-8®:Kd = 389 nM; Fluo-8H:Kd = 232 nM; Fluo-8L:Kd = 1.86 µM; Fluo-8FF :Kd = 10 µM)。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Fluo-8L, 钠盐。

钙离子篇:时间轴式讲解应用于钙离子检测的探针

产品说明书

操作步骤

1.使用钙指示剂AM Esters加载细胞:

        AM酯是非极性酯,其易于穿过活细胞膜,并且通过活细胞内的细胞酯酶快速水解。 AM酯广泛用于非侵入性地将各种极性荧光探针装载到活细胞中。 但是,使用AM酯时必须小心,因为它们易于水解,特别是在溶液中。 它们应在使用前用高质量的无水二甲基亚砜(DMSO)重新配制。 DMSO储备溶液应在-20°C下干燥储存并避光。 在这些条件下,AM酯应稳定数月。

        以下是我们推荐的将AM酯加载到活细胞中的方案。该方案仅提供指南,实际情况应根据您的具体需求进行修改。

a)在高质量无水DMSO中制备2至5 mM AM酯原液。

b)在实验当天,将钙指示剂溶解在DMSO中或将等份的指示剂储备溶液解冻至室温。使用0.02%Pluronic®F-127在您选择的缓冲液(如Hanks和Hepes缓冲液)中制备1至10μM的工作溶液。对于大多数细胞系,我们建议钙指示剂的最终浓度为4-5 uM。 细胞加载所需指标的确切浓度必须根据经验确定。 为避免因过载和潜在染料毒性引起的任何伪影,建议使用可产生足够信号强度的最小探针浓度。

注意:非离子洗涤剂Pluronic®F-127有时用于增加钙指示剂AM酯的水溶性。

c)如果您的细胞含有有机阴离子转运蛋白,可以在细胞培养基中加入丙磺舒(1-2.5 mM)或磺吡酮(0.1-0.25 mM),以减少脱酯化指标的泄漏。 在室温或37°C下用钙指示剂酯孵育细胞20分钟至1小时。

d)在HHBS或您选择的缓冲液(含有阴离子转运蛋白抑制剂,如2.5mM丙磺舒,如果适用)中洗涤细胞1-2次以除去过量的探针。

e)在所需的Ex / Em波长下进行实验(见说明书中的表1)。

 

2.测量细胞内钙响应:

        为了确定溶液的游离钙浓度或单波长钙指示剂的Kd,使用以下等式:[Ca]free = Kd[F – Fmin]/Fmax – F]

        其中F是实验钙水平下指示剂的荧光,Fmin是不存在钙时的荧光,Fmax是钙饱和探针的荧光。 解离常数(Kd)是探针对钙的亲和力的量度。 与校准溶液相比,荧光指示剂的Ca2 +结合和光谱性质在细胞环境中变化非常显着。 细胞内指标的原位校准通常产生显着高于体外测定的Kd值。 通过在离子载体如A-23187,4-溴A-23187和离子霉素存在下将加载的细胞暴露于受控的Ca 2+缓冲液来进行原位校准。 或者,细胞透化剂如洋地黄皂苷或X-100可用于将指示剂暴露于细胞外培养基的受控Ca2 +水平。 说明书中的表1列出了一些钙试剂的Kd值供您参考。

简要概述

钙离子荧光探针Fluo-8L, 钾盐是美国AAT Bioquest生产的用于钙通量测定的试剂,钙测量对于许多生物学研究至关重要。在结合Ca2+后显示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Ca2+浓度的变化。在可见光激发钙指示剂中,Fluo-3和Fluo-4最常用。但是,Fluo-3 AM和Fluo-4 AM在酯酶水解后在活细胞中仅适度发荧光,并且需要苛刻的细胞加载条件才能最大化其细胞钙反应。开发Fluo-8®染料可改善细胞负载和钙响应,同时保持便捷的Fluo-3和Fluo-4光谱波长(在〜490 nm处具有最大激发和在〜520 nm处具有最大发射)。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®的亮度是Fluo-4 AM的2倍,是Fluo-3 AM的4倍。AAT Bioquest提供了一套出色的Fluo-8®试剂,具有不同的钙结合亲和力(Fluo-8®:Kd = 389 nM; Fluo-8H:Kd = 232 nM; Fluo-8L:Kd = 1.86 µM; Fluo-8FF :Kd = 10 µM)。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Fluo-8L, 钾盐。

钙离子篇:时间轴式讲解应用于钙离子检测的探针

产品说明书

操作步骤

1.使用钙指示剂AM Esters加载细胞:

        AM酯是非极性酯,其易于穿过活细胞膜,并且通过活细胞内的细胞酯酶快速水解。 AM酯广泛用于非侵入性地将各种极性荧光探针装载到活细胞中。 但是,使用AM酯时必须小心,因为它们易于水解,特别是在溶液中。 它们应在使用前用高质量的无水二甲基亚砜(DMSO)重新配制。 DMSO储备溶液应在-20°C下干燥储存并避光。 在这些条件下,AM酯应稳定数月。

        以下是我们推荐的将AM酯加载到活细胞中的方案。该方案仅提供指南,实际情况应根据您的具体需求进行修改。

a)在高质量无水DMSO中制备2至5 mM AM酯原液。

b)在实验当天,将钙指示剂溶解在DMSO中或将等份的指示剂储备溶液解冻至室温。使用0.02%Pluronic®F-127在您选择的缓冲液(如Hanks和Hepes缓冲液)中制备1至10μM的工作溶液。对于大多数细胞系,我们建议钙指示剂的最终浓度为4-5 uM。 细胞加载所需指标的确切浓度必须根据经验确定。 为避免因过载和潜在染料毒性引起的任何伪影,建议使用可产生足够信号强度的最小探针浓度。

注意:非离子洗涤剂Pluronic®F-127有时用于增加钙指示剂AM酯的水溶性。

c)如果您的细胞含有有机阴离子转运蛋白,可以在细胞培养基中加入丙磺舒(1-2.5 mM)或磺吡酮(0.1-0.25 mM),以减少脱酯化指标的泄漏。 在室温或37°C下用钙指示剂酯孵育细胞20分钟至1小时。

d)在HHBS或您选择的缓冲液(含有阴离子转运蛋白抑制剂,如2.5mM丙磺舒,如果适用)中洗涤细胞1-2次以除去过量的探针。

e)在所需的Ex / Em波长下进行实验(见说明书中的表1)。

 

2.测量细胞内钙响应:

        为了确定溶液的游离钙浓度或单波长钙指示剂的Kd,使用以下等式:[Ca]free = Kd[F – Fmin]/Fmax – F]

        其中F是实验钙水平下指示剂的荧光,Fmin是不存在钙时的荧光,Fmax是钙饱和探针的荧光。 解离常数(Kd)是探针对钙的亲和力的量度。 与校准溶液相比,荧光指示剂的Ca2 +结合和光谱性质在细胞环境中变化非常显着。 细胞内指标的原位校准通常产生显着高于体外测定的Kd值。 通过在离子载体如A-23187,4-溴A-23187和离子霉素存在下将加载的细胞暴露于受控的Ca 2+缓冲液来进行原位校准。 或者,细胞透化剂如洋地黄皂苷或X-100可用于将指示剂暴露于细胞外培养基的受控Ca2 +水平。 说明书中的表1列出了一些钙试剂的Kd值供您参考。

        以下是我们推荐的将AM酯加载到活细胞中的方案。该方案仅提供指南,实际情况应根据您的具体需求进行修改。

a)在高质量无水DMSO中制备2至5 mM AM酯原液。

b)在实验当天,将钙指示剂溶解在DMSO中或将等份的指示剂储备溶液解冻至室温。使用0.02%Pluronic®F-127在您选择的缓冲液(如Hanks和Hepes缓冲液)中制备1至10μM的工作溶液。对于大多数细胞系,我们建议钙指示剂的最终浓度为4-5 uM。 细胞加载所需指标的确切浓度必须根据经验确定。 为避免因过载和潜在染料毒性引起的任何伪影,建议使用可产生足够信号强度的最小探针浓度。

注意:非离子洗涤剂Pluronic®F-127有时用于增加钙指示剂AM酯的水溶性。

c)如果您的细胞含有有机阴离子转运蛋白,可以在细胞培养基中加入丙磺舒(1-2.5 mM)或磺吡酮(0.1-0.25 mM),以减少脱酯化指标的泄漏。 在室温或37°C下用钙指示剂酯孵育细胞20分钟至1小时。

d)在HHBS或您选择的缓冲液(含有阴离子转运蛋白抑制剂,如2.5mM丙磺舒,如果适用)中洗涤细胞1-2次以除去过量的探针。

e)在所需的Ex / Em波长下进行实验(见说明书中的表1)。

 

2.测量细胞内钙响应:

        为了确定溶液的游离钙浓度或单波长钙指示剂的Kd,使用以下等式:[Ca]free = Kd[F – Fmin]/Fmax – F]

        其中F是实验钙水平下指示剂的荧光,Fmin是不存在钙时的荧光,Fmax是钙饱和探针的荧光。 解离常数(Kd)是探针对钙的亲和力的量度。 与校准溶液相比,荧光指示剂的Ca2 +结合和光谱性质在细胞环境中变化非常显着。 细胞内指标的原位校准通常产生显着高于体外测定的Kd值。 通过在离子载体如A-23187,4-溴A-23187和离子霉素存在下将加载的细胞暴露于受控的Ca 2+缓冲液来进行原位校准。 或者,细胞透化剂如洋地黄皂苷或X-100可用于将指示剂暴露于细胞外培养基的受控Ca2 +水平。 说明书中的表1列出了一些钙试剂的Kd值供您参考。

基本描述 This is a negative control peptide containing the reversed sequence of the first two amino acids of the receptor-activating (tethered ligand) peptide SFLLRN-NH2. It shows no detectable affinity for the binding sites. Whereas SFLLRN-NH2 effectively displaces [3H]haTRAP, thrombin receptor-activating peptide, the same peptide with serine and phenylalanine reversed, FSLLRN-NH2, does not.

产品介绍

钙离子荧光探针Fluo-8FF, AM 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。在结合Ca2+后显示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Ca2+浓度的变化。在可见光激发钙指示剂中,Fluo-3和Fluo-4最常用。但是,Fluo-3 AM和Fluo-4 AM在酯酶水解后在活细胞中仅适度发荧光,并且需要苛刻的细胞加载条件才能最大化其细胞钙反应。开发Fluo-8®染料可改善细胞负载和钙响应,同时保持便捷的Fluo-3和Fluo-4光谱波长(在〜490 nm处具有最大激发和在〜520 nm处具有最大发射)。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®的亮度是Fluo-4 AM的2倍,是Fluo-3 AM的4倍。AAT Bioquest提供了一套出色的Fluo-8®试剂,具有不同的钙结合亲和力(Fluo-8®:Kd = 389 nM; Fluo-8H:Kd = 232 nM; Fluo-8L:Kd = 1.86 µM; Fluo-8FF :Kd = 10 µM)。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Fluo-8FF, AM 。

简要概述

Cell Meter 荧光法细胞内pH检测试剂盒  是美国AAT Bioquest生产的胞内pH检测试剂盒,细胞内pH变化涉及多种生理和病理过程,包括细胞增殖,细胞凋亡,受精,恶性肿瘤,多药耐药性,离子转运,溶酶体贮积症和阿尔茨海默病。 Cell Meter 荧光细胞内pH测定试剂盒利用AAT Bioquest专有的荧光指示剂测量相对细胞内pH变化。它是一种均相的,动力学的活细胞荧光测定法,它使用标准程序或酸负荷程序。设计标准方案用于治疗靶标,同时治疗时细胞内pH降低。 “酸负荷”程序旨在测量与GPCR活化或生长因子活性引起的细胞代谢变化相关的细胞内pH的增加。在“酸负荷”程序中,在将荧光pH染料以最小体积加载到细胞中之后加入氯化铵溶液。该“酸加载”步骤之后是在相对大体积(~4X)的缓冲液中加入激动剂。突然的体积变化引发来自细胞的氨(NH 3)流出,导致细胞内pH的快速降低,并因此导致荧光信号的降低。通过相对荧光信号增加测量激动剂对随后的细胞内pH恢复的影响。金畔生物是AAT Bioquest 的中国代理商,为您提供最优质的Cell Meter 荧光法细胞内pH检测试剂盒 。

操作步骤

运行pH测定以获得标准细胞

1.将100μL/孔(96孔板)或25μL/孔(384孔板)RatioWorks TM BCFL,AM染料加工溶液加入到细胞板中。注意:如果化合物干扰血清,重要的是用HHBS缓冲液替换生长培养基(96孔板100μL/孔或染料加载前384孔板25μL/孔)。

2.将染料加载板在细胞培养箱中孵育30分钟,然后在室温下将板孵育另外30分钟。注意:如果测定需要37°C,立即进行实验,无需进一步室温孵育。

3.使用HHBS或所需的缓冲液制备复合板。

4.通过监测Ex / Em = 490 / 535nm(截止= 515nm)或505 / 535nm和430 / 535nm(截止= 515nm)处的荧光进行pH测定以进行比率测量。添加化合物为50μL/孔(96孔板)或25μL/孔(384孔板)。注意:化合物应在化合物添加后3至5分钟内完成,但在测定开发过程中建议至少8分钟的数据收集。

 

运行pH测定酸

1.从细胞板上除去生长培养基。

2.将50μL/孔/ 96孔板RatioWorks™BCFL,AM染料加工溶液添加到细胞板中。

3.将染料加载板在细胞培养箱中孵育30分钟,然后在室温下将板孵育另外30分钟。注意:如果测定需要37°C,立即进行实验,无需进一步室温孵育。

4.加入5μL的220mM NH 4 Cl并将板离心5秒。在室温下孵育15分钟。注意:NH4Cl溶液应在HHBS(组分C)中新鲜制备。

5.使用HHBS或所需的缓冲液制备复合板。

6.通过监测Ex / Em = 490 / 535nm(截止= 515nm)或505 / 535nm和430 / 535nm(截止= 515nm)处的荧光进行pH测定以进行比率测量。添加的化合物为200μL/孔/ 96孔板。注意:化合物应在化合物添加后3至5分钟内完成,但在测定开发过程中建议至少8分钟的数据收集。

 

示例数据分析和数据

        从空白标准孔获得的读数(RFU)用作阴性对照。 从其他标准的读数中减去该值,以获得基线校正值。 然后,绘制标准读数以获得标准曲线和方程。 该等式可用于计算Carbachol样品。

图1. CHO-M1细胞中的卡巴胆碱剂量反应。 在96孔黑壁/透明底板中,将CHO-M1细胞以每100μL/孔60,000个细胞接种过夜。 将生长培养基用50μL/孔的RatioWorks BCFL,AM染料加载溶液替换37℃1小时,然后用5μL/孔的220mM NH 4 Cl孵育15分钟。 通过FlexStation(Molecular Devices)添加Carbachol(200μL/孔)以达到最终指示的浓度。 使用Ex / Em = 490 / 535nm(截止= 515nm)产生荧光信号。
