线粒体膜电位检测试剂盒—JC-1 MitoMP Detection Kit货号:MT09

产品概述

细胞中的线粒体作为有氧呼吸产生ATP的主要场所,是体内重要的细胞器之一,常被用于早期细胞毒性、氧化应激、细胞凋亡等研究中1)。线粒体活性的降低与机能失调,已被证实与癌症、衰老、神经退行性疾病 (如阿尔兹海默症、帕金森病等) 等密切相关2)3)

JC-1是一种被广泛使用的小分子线粒体膜电位探针,依赖于线粒体膜电位在线粒体中聚集,染料伴随聚集过程,荧光从绿色 (530 nm) 变为红色 (590 nm)。当线粒体发生去极化,红/绿荧光强度比值降低。以往的研究者反映,JC-1不易溶于水并有大量沉淀产生。但与其他公司的产品不同,同仁化学研究所研制的JC-1试剂解决了这一问题,避免了沉淀的产生。同时使用试剂盒中配制的成像缓冲液 (Imaging Buffer),可大幅降低荧光背景并在检测过程中保护细胞不受损伤。

当JC-1工作液的浓度为2 μmol/l, 每次用量为100 μl时,可以检测500次。

产品特点

1.为什么要检测线粒体膜电位

线粒体不仅是细胞内产生能量的场所,它还与癌症、衰老、阿尔兹海默症、帕金森等神经变异性疾病密切相关。因此,针对线粒体状态的研究非常重要,其中线粒体膜电位的变化经常被作为重要的指标之一检测。

当线粒体正常、膜电位差保持不变时,JC-1会聚集并发出红色荧光,而当膜电位降低时,JC-1会作为单体存在并发出绿色荧光。红色和绿色荧光强度的变化可以作为检测线粒体状态的指标。

2.初次使用也很容易上手

3.去极化的检测实例

使用去极化剂carbonylcyanide-p-trifluoromethoxyphenylhydrazone(FCCP)对HeLa细胞进行处理,用本试

剂盒进行检测。可以发现与未加药物的细胞相比,加药组细胞的红色荧光明显减少。

2.诱导自噬的实验例

使用表达Parkin的HeLa细胞,分别使用线粒体自噬试剂盒(Mitophagy Detection Kit:MD01)和线粒体膜电位检测试剂盒(JC-1 MitoMP Detection Kit: MT09)来观察添加和不添加CCCP(羰基氰化物间氯苯)的线粒体状态的变化。

结果证明在未经CCCP处理的细胞中几乎未检测到线粒体自噬的发生,并且线粒体膜电位正常维持。 而在添加了CCCP的细胞中,证实了线粒体膜电位的降低(JC-1的红色荧光的降低)和线粒体的自噬(Mtphagy染料的荧光的增强)。

红色Ex:561 nm,Em:560-610 nm

实验条件

1.将Parkin质粒导入HeLa细胞

使用HilyMax(货号:H357)将Parkin质粒引入HeLa细胞中(Parkin质粒/HilyMax试剂:0.1 μg/0.2 μl)

然后过夜培养,收集细胞进行以下检测。

2.自噬检测

向表达Parkin的HeLa细胞中添加0.1 μmol/l Mtphagy工作溶液,并在37°C下孵育30分钟。然后将细胞用HBSS洗涤,加入10 μg/ml CCCP/MEM溶液,并在37℃下孵育2小时。荧光显微镜下观察处理后的细胞。

3.线粒体膜电位检测

将10 μg/ml的CCCP/MEM溶液添加至表达Parkin的HeLa细胞中,并在37℃下孵育1.5小时。加入4 μmol/l的JC-1工作溶液使终浓度至2 μmol/l,并将细胞溶液在37℃下孵育30分钟。孵育后将细胞用HBSS洗涤,加入成像缓冲液,在荧光显微镜下观察细胞。

3.线粒体膜电位与细胞周期关联性

将已知能在细胞周期的G2/M期起作用以终止细胞增殖并诱导细胞衰老的阿霉素(DOX)加入A549细胞后,

使用细胞周期检测试剂盒蓝色(产品代码:C549)/深红色(产品代码:C548)后检测。

结果证实了A549细胞的细胞周期确实发生了变化,同时用细胞衰老检测试剂盒–SPiDER-βGal(产品代码:SG03)证实了细胞产生衰老,实验证实了线粒体膜电位会发生变化。

常见问题Q&A

Q1: 本试剂盒可以检测多少次?
A1:大概的使用次数请参考下表:
检测装置 容器 使用次数 液量
流式细胞仪 100次 0.5 ml/次
荧光显微镜
荧光酶标仪
35 mm dish 25块板 2 ml/孔
8孔Chamber Slide 30块板 200 μl/孔
96孔板 5块板 100 μl/孔
Q2:在JC-1染色后,可以使用PBS代替HBSS洗涤吗?
A2:我们建议使用HBSS来减少对细胞的损伤。如果您手边没有HBSS的话,建议使用培养基洗净。
Q3:可以使用含血清的培养基吗?
A3:在清洗细胞和Working Solution中可以使用含血清的培养基。在观察荧光时建议使用Imaging Buffer。如果一定要使用含血清的培养基的话,建议不要加酚红。
Q4:染色后细胞固定或者固定后进行染色可以实现吗?
A4:细胞固定操作会使得线粒体去极化,所以染色前后均不能进行细胞固定。
 

Q5:处理后的样品与对照组相比较,红和绿两种荧光值都增加(或减少)了,结果该如何解释?

A5:请先比较实验组和对照组的荧光比值,两者相比,荧光比越低,线粒体膜电位越低。

用荧光之比进行结果分析的理由。

JC-1由于膜电位依存性地在细胞中积蓄,根据细胞的状态,每个细胞的JC-1的浓度有可能不同。

由于对照组和实验组处理样品的细胞状态不同,JC-1的累积浓度不同。)

另外,在线粒体膜电位较高的状态下,JC-1会聚集在一起,使荧光从绿色转移到红色。

该聚集体的量取决于膜电位的程度,因此可以用红/绿之比来比较样品之间的线粒体膜电位。

产品概述

细胞中的线粒体作为有氧呼吸产生ATP的主要场所,是体内重要的细胞器之一,常被用于早期细胞毒性、氧化应激、细胞凋亡等研究中1)。线粒体活性的降低与机能失调,已被证实与癌症、衰老、神经退行性疾病 (如阿尔兹海默症、帕金森病等) 等密切相关2)3)

JC-1是一种被广泛使用的小分子线粒体膜电位探针,依赖于线粒体膜电位在线粒体中聚集,染料伴随聚集过程,荧光从绿色 (530 nm) 变为红色 (590 nm)。当线粒体发生去极化,红/绿荧光强度比值降低。以往的研究者反映,JC-1不易溶于水并有大量沉淀产生。但与其他公司的产品不同,同仁化学研究所研制的JC-1试剂解决了这一问题,避免了沉淀的产生。同时使用试剂盒中配制的成像缓冲液 (Imaging Buffer),可大幅降低荧光背景并在检测过程中保护细胞不受损伤。

当JC-1工作液的浓度为2 μmol/l, 每次用量为100 μl时,可以检测500次。

产品特点

1.为什么要检测线粒体膜电位

线粒体不仅是细胞内产生能量的场所,它还与癌症、衰老、阿尔兹海默症、帕金森等神经变异性疾病密切相关。因此,针对线粒体状态的研究非常重要,其中线粒体膜电位的变化经常被作为重要的指标之一检测。

当线粒体正常、膜电位差保持不变时,JC-1会聚集并发出红色荧光,而当膜电位降低时,JC-1会作为单体存在并发出绿色荧光。红色和绿色荧光强度的变化可以作为检测线粒体状态的指标。

2.诱导自噬的实验例

使用表达Parkin的HeLa细胞,分别使用线粒体自噬试剂盒(Mitophagy Detection Kit:MD01)和线粒体膜电位检测试剂盒(JC-1 MitoMP Detection Kit: MT09)来观察添加和不添加CCCP(羰基氰化物间氯苯)的线粒体状态的变化。

结果证明在未经CCCP处理的细胞中几乎未检测到线粒体自噬的发生,并且线粒体膜电位正常维持。 而在添加了CCCP的细胞中,证实了线粒体膜电位的降低(JC-1的红色荧光的降低)和线粒体的自噬(Mtphagy染料的荧光的增强)。

3.线粒体膜电位检测

将10 μg/ml的CCCP/MEM溶液添加至表达Parkin的HeLa细胞中,并在37℃下孵育1.5小时。加入4 μmol/l的JC-1工作溶液使终浓度至2 μmol/l,并将细胞溶液在37℃下孵育30分钟。孵育后将细胞用HBSS洗涤,加入成像缓冲液,在荧光显微镜下观察细胞。

常见问题Q&A

Q1: 本试剂盒可以检测多少次?
A1:大概的使用次数请参考下表:
检测装置 容器 使用次数 液量
流式细胞仪 100次 0.5 ml/次
荧光显微镜
荧光酶标仪
35 mm dish 25块板 2 ml/孔
8孔Chamber Slide 30块板 200 μl/孔
96孔板 5块板 100 μl/孔
Q2:在JC-1染色后,可以使用PBS代替HBSS洗涤吗?
A2:我们建议使用HBSS来减少对细胞的损伤。如果您手边没有HBSS的话,建议使用培养基洗净。
Q3:可以使用含血清的培养基吗?
A3:在清洗细胞和Working Solution中可以使用含血清的培养基。在观察荧光时建议使用Imaging Buffer。如果一定要使用含血清的培养基的话,建议不要加酚红。
Q4:染色后细胞固定或者固定后进行染色可以实现吗?
A4:细胞固定操作会使得线粒体去极化,所以染色前后均不能进行细胞固定。
 

Q5:处理后的样品与对照组相比较,红和绿两种荧光值都增加(或减少)了,结果该如何解释?

A5:请先比较实验组和对照组的荧光比值,两者相比,荧光比越低,线粒体膜电位越低。

用荧光之比进行结果分析的理由。

JC-1由于膜电位依存性地在细胞中积蓄,根据细胞的状态,每个细胞的JC-1的浓度有可能不同。

由于对照组和实验组处理样品的细胞状态不同,JC-1的累积浓度不同。)

另外,在线粒体膜电位较高的状态下,JC-1会聚集在一起,使荧光从绿色转移到红色。

该聚集体的量取决于膜电位的程度,因此可以用红/绿之比来比较样品之间的线粒体膜电位。

产品概述

线粒体利用氧气合成ATP,从而产生细胞所需的能量,是重要的细胞器之一。线粒体活性低下和机能障碍与癌症、老化、阿尔茨海默病、帕金森病等神经变性疾病密切相关。因此,线粒体膜电位(MMP)作为线粒体相关疾病的一个有希望的靶点已被广泛研究。

产品特点

解决传统试剂的三个问题

观察线粒体膜电位时,使用JC-1、TMRE、TMRM,但由于PFA不可固定、容易淬灭,数据的再现性等问题。MT-1 MitoMP Detection Kit是克服了这些问题的线粒体膜电位的检测试剂。

并且,通过本试剂盒中包含的Imaging Buffer,可以在抑制了荧光背景和对细胞的损伤的状态下进行观察。

①固定后也可检测

由于微小的细胞状态的变化,也会造成线粒体膜电位发生变化,所以取得数据的重现性需要特别注意。通用的线粒体膜电位检测试剂(JC-1、TMRE)如果对细胞进行固定处理的话会失去荧光,所以需要使用活细胞进行迅速的测定。MT-1即使进行染色后进行PFA固定操作,也能保持荧光,因此可以进行高重复性的实验。

线粒体膜电位检测试剂盒货号:MT13

②可监控

没有进行药物刺激的细胞通过各种试剂染色,确认了荧光强度的变化。结果,JC-1和TMRE在染色后约10分钟左右荧光强度下降,MT-1仍保持了一定的荧光强度

线粒体膜电位检测试剂盒货号:MT13

③高灵敏度

线粒体膜电位的细微变化在JC-1中有难以检测的情况,在这种情况下,使用四甲基罗丹明乙酯(TMRE)监测MMP。MT-1可提供与TMRE同等的检测灵敏度。

实验例

1.通过去极化的实验例

通过线粒体去极化剂的cyanide-p-trifluoromethoxyphenylhydrazone (FCCP)处理HeLa细胞,用该试剂观察膜电位的变化。

线粒体膜电位检测试剂盒货号:MT13

结果,确认了FCCP处理的细胞线粒体膜电位下降的情况。

2.凋亡诱导细胞线粒体膜电位的变化

预先在MT-1中染色的HL60细胞中添加Etoposide,诱导凋亡后,与Annexin V、FITC Conjugate一同染色,并通过流式细胞仪检测。

线粒体膜电位检测试剂盒货号:MT13

结果发现Annexin V-FITC产生的荧光强度变化(绿色荧光强度的增加)确认了凋亡的发生,以及从MT-1产生的荧光强度变化(红色荧光强度的降低)发现了线粒体膜电位的变化。

3.同时评估线粒体超氧化物和膜电位

用 HBSS 冲洗 HeLa 细胞后,用 MT-1 线粒体氧化酶检测试剂盒和线粒体超氧化物检测染料((mtSOX Deep Red: MT14)共同染色,同时观察线粒体 ROS 和膜电位的产生情况。因此,线粒体膜电位的降低和线粒体 ROS 的产生是同时观察到的。

常见问题Q&A

Q1:使用荧光显微镜检测时需要注意什么?
A1:请尽量减少激发光照射时间并提高检测灵敏度。

细胞长期暴露于激发光内可能导致细胞损伤和荧光染料降解,请优化检测时间。

Q2:MT-1检测后可以固定吗?
A2:应使用4%多聚甲醛(PFA)固定,且不能与(Triton X-100、NP-40等)一起使用,因为这可能导致染泄漏。
Q3:固定后可以对细胞染色吗?
A3:由于MT-1在线粒体中的积累取决于线粒体膜电位,因此固定后不适用于染色。
Q4:是否需要做阳性对照?
A4:作为阳性对照,可在技术手册中找到使用FCCP(羰基氰化物-对三氟甲氧基苯腙)的实验例。
 

Q5:优化染色条件时,应使用何种浓度的MT-1染料

 

A5:MT-1染料的浓度建议稀释1000倍。但在优化染色条件时,请参考以下内容。

<荧光强度弱>

请优化以下浓度:稀释500-1000倍。

<观察到非特异性吸附>

请优化以下浓度:稀释1000至2000倍。

Q6:我可以使用缓冲液来制备MT-1工作溶液吗?
A6:可以使用Hanks的HEPES和HBSS。也可以使用MEM、RPMI和含10%FBS的MEM制备。
Q7:添加MT-1工作液后,可以不清洗直接上机检测吗?
A7:染色后,无需清洗即可观察样品。但我们不建议在不清洗的情况下长期观察它们,因为它们可能具有细胞毒性。

我们建议去除上清液并用培养基替换。

Q8:MT-1染色后,是否可以用PBS代替HBSS来清洗?
A8:我们建议使用HBSS来减少细胞损伤。如果您没有HBSS,我们建议使用培养基来代替清洗。

生物活性

JC-1 (CBIC2) is a fluorescent lipophilic carbocyanine dye used to measure mitochondrial membrane potential. JC-1 forms complexes known as J-aggregates at high ΔΨm. Aggregates of JC-1 emit an orange-red fluorescence (Ex/Em=585/590 nm). While in cells with low ΔΨm, JC-1 remains in the monomeric form. JC-1 monomers emit a green fluorescence (Ex/Em=510/527 nm).

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Labeling of Cells:
1. Culture cells in 6-, 12- , 24-, or 96-well plates at a density of 5× 105 cells/mL. Incubate the cells according to your normal protocol.
2. Ensure that the JC-1 and DMSO has equilibrated to room temperature, and then prepare a 200 μM stock solution by dissolving the contents of one vial in DMSO provided.
3. For the control tube, allow the vial of CCCP has come to room temperature, add 1 μL of CCCP (50 mM). Incubate cells at 37°C for 5 minutes.
4. Add 10 μL JC-1 (200 μM) per well to make the final concentration at 2 μM. Incubate cells at 37°C, 5% CO2, for 15-20 minutes. If additional labeling followed, for example with an annexin V, begin with step 2.a. If not, proceed with step 1.e.
5. After incubation, centrifuge cells for 3-4 minutes at 400× g at 4°C, carefully aspirate the supernant.
6. Wash cells twice with PBS (1×): add 2 mL PBS (1×) to suspend cells and vortex to mix thoroughly. Centrifuge cells for 3-4 minutes at 400× g at 4°C, carefully aspirate the supernant.
7. Add 500 μL PBS (1×) to suspend cells. Analyze sample on a flow cytometer, fluorescence microscopy, or fluorescence microplate reader.

    以 1 mL 工作液为例,取 100 μL 12.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。

    将 0.9 g 氯化钠,完全溶解于 100 mL ddH₂O 中,得到澄清透明的生理盐水溶液
