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。

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

使用Fluo-8®AM酯类

1.使用Fluo-8®AM酯:

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。它们应在使用前重新配制成高质量的无水二甲基亚砜(DMSO)。DMSO储备溶液可以在-20℃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Fluo-8®AM酯加入活细胞的方案。该协议仅提供指南,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 Fluo-8®AM酯原液。

b)在实验当天,将Fluo-8® 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0.02%Pluronic®F-127的缓冲液中制备1至10μM的工作溶液。对于大多数细胞系,建议使用浓度范围为4-5 uM的Fluo-8®试剂。细胞加载所需指示剂的确切浓度必须凭经验确定。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染料浓度。

注意:非离子洗涤剂Pluronic®F-127有时用于增加Fluo-8®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渗漏。

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)在细胞培养箱中孵育或染料装载板室温下为20分钟至一小时。

f)用HHBS或您选择的缓冲液(含有阴离子转运蛋白抑制剂,如2.5 mM丙磺舒,如果适用)替换染料工作溶液,以去除多余的探针。

g)运行用Ex / Em比值=490/525纳米

 

使用Screen Quest Fluo-8 NW钙测定试剂盒进行HTS应用

        可以通过直接测量受体介导的cAMP积累或细胞内Ca2+浓度的变化来检测GPCR活化。通过Gq偶联的GPCR靶标产生细胞内Ca2+的增加可以使用Fluo-8®试剂和荧光酶标仪的组合进行测量。荧光成像板读取器(例如,FLIPR,FDSS或BMG NovoStar)具有冷却的CCD相机成像系统,其同时收集来自微孔板(96孔和384孔)的每个孔的信号。这些读板器可以以亚秒的间隔读取,这使得能够捕获响应的动力学,并且具有可以被编程用于连续液体添加的集成移液器。除了对GPCR靶标的强大应用外,我们的Screen Quest Fluo-8钙测定试剂盒还可用于表征钙离子通道和筛选钙离子通道靶向化合物。

图1.使用Screen Quest Fluo-8 NW测定试剂盒和Fluo-4 NW测定试剂盒在HEK-293细胞中测量卡巴胆碱剂量反应 将HEK-293细胞以40,000个细胞/100μL/孔接种过夜,置于96孔黑色壁/透明底板中。除去生长培养基,并将细胞分别与100μL的Screen Quest Fluo 8-NW钙测定试剂盒和Fluo-4 NW试剂盒(根据制造商的说明书)在室温下温育1小时。通过NOVOstar(BMG LabTech)添加卡巴胆碱(25μL/孔)以达到最终指示的浓度。Fluo-8 NW 的EC 50约为1.2 uM。

与基于Fluo-3或Fluo-4的其他商业钙测定试剂盒相比,我们的Screen Quest 钙测定试剂盒具有以下HTS应用优势:

  • 广泛的应用:与GPCR和钙通道目标一起使用。
  • 方便的光谱波长:最大激发波长@ 490 nm; 最大发射@ ~514 nm。
  • 灵活的染料加载:室温下的染料加载(而不是Fluo-4 AM所需的37ºC)。
  • 无需清洗,无淬火干扰您的目标。
  • 强大的性能:使用Fluo-4 AM或Fluo-3 AM无法进行钙分析。
  • 最强信号强度:比Fluo-4 AM亮2倍;比Fluo-3 AM亮4倍。

使用Fluo-8® 

        钙校准可以通过测量具有精确已知的游离Ca 2+浓度的溶液中的指示剂的盐形式(荧光酶标仪中25至50μM)的荧光强度来进行。可以基于30mM MOPS EGTA Ca 2+缓冲液使用校准溶液。通常,水含有微量的钙离子。强烈建议使用30 mM MOPS + 100 mM KCl,pH 7.2作为缓冲系统。可以简单地制备如下所列的0和39μM钙原液,这两种溶液用于制备不同Ca 2+浓度的连续溶液

A.0μM钙:30mM MOPS + 100mM KCl,pH 7.2缓冲液+ 10mM EGTA

B.39μM钙:30mM MOPS + 100mM KCl,pH 7.2缓冲液+ 10mM EGTA + 10mM CaCl 2

 

为了确定溶液的游离钙浓度或 单波长钙指示剂的K d,使用以下等式:

的[Ca] 游离 = K d [F─˚F 分钟 ] / F 最大 ─F]

其中F是特定实验钙水平下指示剂的荧光强度,F min是不存在钙时的荧光强度,F max是钙饱和探针的荧光强度。

 

解离常数(K d)是探针对钙的亲和力的量度。与校准溶液相比,荧光指示剂的钙结合和光谱性质在细胞环境中变化非常显着。细胞内指标的原位反应校准通常产生显着高于体外测定的K d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Triton®X-100可用于将指示剂暴露于受控Ca.2+水平的细胞外培养基。

产品介绍

钙离子荧光探针Fluo-8L, 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提供了一套我们的出色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)。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;10×50 µg;20×50 µg;HTS包装,不收取额外包装费用。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, AM 。

产品介绍

D-荧光素醋酸是美国AAT Bioquest生产的荧光染料,D-荧光素乙酯含有在羧基位置连接的甲基部分,因此防止它被萤火虫荧光素酶识别。 然而,酯通过脂肪酶活性有效地水解,并且所得的D-荧光素被荧光素酶很好地识别。 D-荧光素甲酯是用于在均相测定中或在与荧光素酶及其辅因子组合的细胞裂解物样品中化学发光测量脂肪酶活性的敏感底物。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的D-荧光素醋酸。

简要概述

Amplite 荧光素酶报告基因检测试剂盒是美国AAT Bioquest生产的用于荧光素酶报告基因检测的试剂盒。β-半乳糖苷酶,β-葡萄糖醛酸酶和荧光素酶是常见的报告基因。最好的多功能常见报告基因是来自于北美的萤火虫Photinus pyralis的荧光素酶。此酶蛋白的活性不需要进行蛋白质翻译后修饰获得。它在活细胞中高浓度积累不会造成细胞毒性,可以在原核和真核细胞中使用。在ATP、镁离子和氧存在的条件下,萤火虫荧光素酶催化荧光素氧化形成生物荧光。Amplite 荧光素酶报告基因检测试剂盒利用与荧光强度相关的公式来定量检测活细胞和细胞抽提物中的荧光素酶。在荧光素酶的催化下,我们的试剂/试剂盒会产生具有强烈荧光的荧光产物。本试剂盒提供所有的必需组分,并且经过优化处理,我们还提供可以用于HTS(高通量筛选)实验方案。本试剂盒具有非常好的灵敏度,可以用于对灵敏度有要求的分析。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的Amplite 荧光素酶报告基因检测试剂盒。

产品说明书

分离细胞的检测方案

概述

用密度为5×105到2×106个细胞/ mL的测试化合物制备细胞

将FAM-YVAD-FMK以1:150的比例加入到细胞溶液中

在室温下孵育1小时

将细胞沉淀,用缓冲液或生长培养基洗涤并重悬细胞

在Ex / Em = 490 / 525nm处分析细胞

注:使用前将所有部件在室温下解冻。

 

操作方法

1.根据您的特异性诱导方案,将细胞培养至最适于细胞凋亡诱导的密度,但不超过2 x 106个细胞/ mL。同时,对于每种标记条件,以与诱导群体相同的密度培养非诱导的阴性对照细胞群。以下是一些诱导悬浮培养细胞凋亡的例子:

1)用2μg/ ml喜树碱处理Jurkat细胞3小时。

2)用1μM星形孢菌素处理Jurkat细胞3小时。

3)用4μg/ ml喜树碱处理HL-60细胞4小时。

4)用1μM星形孢菌素处理HL-60细胞4小时。

注意:应对每个细胞系进行单独评估,以确定诱导细胞凋亡的最佳细胞密度。

2.通过向FAM-YVAD-FMK(组分A)的小瓶中加入50μLDMSO制备150X FAM-YVAD-FMK DMSO储备溶液。

3.将150×FAM-YVAD-FMK DMSO储备溶液(来自步骤1)以1:150的比例添加到细胞溶液中,并将细胞在37℃,5%CO 2培养箱中孵育1小时。

注1:对于FAM-YVAD-FMK标记,细胞可以浓缩至~5×10 6个细胞/ mL。 未使用的150X FAM-YVAD-FMK DMSO储备溶液应分为单次使用的等分试样并储存在-20°C。

注2:对于粘附细胞,用0.5mM EDTA轻轻提起细胞以保持细胞完整,并在用FAM-YVAD-FMK孵育之前用含血清的培养基洗涤细胞一次。

注3:适当的孵育时间取决于所用的细胞类型和细胞浓度。 优化每个实验的孵育时间。

4.将细胞以约200g旋转5分钟,并用1mL洗涤缓冲液(组分B)洗涤细胞两次。 将细胞重悬于所需量的洗涤缓冲液中。

注1:FAM-YVAD-FMK是荧光的,因此清除任何未结合的试剂以消除背景非常重要。

注2:对于分离的细胞,应将细胞浓度调节至每个微量滴定板孔中2-5×10 5个细胞/100μL等分试样,用于步骤6。

5.如果需要,用DNA染色标记细胞(如用于死细胞的碘化丙锭,或用于细胞核染色的整个群体的Hoechst)。

6.通过荧光显微镜,流式细胞仪或荧光酶标仪在Ex / Em = 490 / 525nm处检测荧光强度(对于碘化丙锭,Ex / Em = 535/635 nm;对于Hoechst染料,Ex / Em = 350 / 461纳米)。

6.1对于流式细胞仪,使用FL1通道监测荧光强度(FL2通道用于碘化丙锭染色)。

6.2用于荧光显微镜和荧光酶标仪。将100μL细胞悬浮液置于96孔黑壁/微量滴定板透明底部的每个孔中。

注意:如果需要平衡细胞浓度,调整诱导细胞的悬浮体积以接近非诱导细胞群的细胞密度。如果您的细胞治疗不会导致受刺激细胞群数量的显着损失,则此调整步骤是可选的。

6.3使用FITC通道在荧光显微镜下观察细胞(用于碘化丙啶染色的TRITC通道,用于Hoechst染色的DAPI通道)。

6.4使用荧光酶标仪,使用Ex / Em = 490 / 525nm(在515nm处截止)底部读取模式监测荧光强度。

产品详细介绍

简要概述

Amplite NAD/NADH比率检测试剂盒(比色法)是美国AAT Bioquest研发的检测NAD/NADH的试剂盒,烟酰胺腺嘌呤二核苷酸(NAD)和烟酰胺腺嘌呤二核苷酸磷酸(NADP)是细胞中发现的两种重要的辅酶。 NAD形成NADP,通过酯键将磷酸基团添加到腺苷核苷酸的2’位置。 NADH(NADPH)是NAD(NADP)的还原形式,NAD(NADP)是NADH(NADPH)的氧化形式。 NAD或NADP在氧化还原反应中起辅助因子的作用,在细胞反应中转移电子。 氧化形式和还原形式之间的平衡是NAD / NADH(NADP / NADPH)比率。 该比率是指示细胞氧化还原状态的重要组分,并且它是反映代谢活性和细胞健康的测量。 在健康的哺乳动物组织中,游离NAD +和NADH之间的比率的估计可以高达700.相反,NADP / NADPH比率通常为约0.005,因此NADPH是该辅酶的主要形式。

该Amplite 比色NAD / NADH比率分析试剂盒提供了一种比色法,用于测量培养细胞中细胞内总NAD / NADH量和NAD / NADH比率。 在该测定中,裂解物中的NAD可以用NAD提取溶液提取并通过酶反应转化为NADH,然后通过NADH探针识别,在反应后得到黄色染料,其在460nm处具有吸光度。 产生的染料量与细胞裂解物中NAD或NADH的浓度成正比,可用作细胞NAD / NADH浓度的指示剂。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的NAD/NADH检测试剂盒。

简要概述

Amplite NADP/NADPH比率检测试剂盒 (比色法)是美国AAT Bioquest研发的检测NADP/NADPH的试剂盒,烟酰胺腺嘌呤二核苷酸(NAD)和烟酰胺腺嘌呤二核苷酸磷酸(NADP)是细胞中发现的两种重要的辅酶。 NAD形成NADP,通过酯键将磷酸基团添加到腺苷核苷酸的2’位置。 NADH(NADPH)是NAD(NADP)的还原形式,NAD(NADP)是NADH(NADPH)的氧化形式。 NAD或NADP在氧化还原反应中起辅助因子的作用,在细胞反应中转移电子。 氧化形式和还原形式之间的平衡是NAD / NADH(NADP / NADPH)比率。 该比率是指示细胞氧化还原状态的重要组分,并且它是反映代谢活性和细胞健康的测量。 在健康的哺乳动物组织中,游离NAD和NADH之间的比率的估计可以高达700。相反,NADP / NADPH比率通常为约0.005,因此NADPH是该辅酶的主要形式。

该Amplite 比色NADP / NADPH比率分析试剂盒提供了一种比色法,用于测量培养细胞中细胞内总NADP / NADPH量和NADP / NADPH比率。 在该测定中,裂解物中的NADPH可以用NADPH提取溶液提取,然后通过NADPH探针识别,在反应后得到黄色染料,其在460nm处具有吸光度。 产生的染料量与细胞裂解物中NADP或NADPH的浓度成正比,可用作细胞NADP / NADPH浓度的指示剂。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的NADP/NADPH检测试剂盒。
