OCR是线粒体功能的重要指标

由于氧主要在线粒体氧化磷酸化产生三磷酸腺苷(ATP)的过程中消耗,因此其耗氧率(OCR)是分析线粒体功能的指标。众所周知,癌细胞通过糖酵解途径产生ATP,其效率低于氧化磷酸化。在免疫细胞中,氧化磷酸化的优势是抑制抗肿瘤,而糖酵解途径的优势促进抗肿瘤作用。因此,细胞的OCR作为能量代谢的检测指标。

产品概述

细胞外氧消耗量试剂盒包括氧气探针,其具有随着介质中氧气浓度的降低而增加荧光强度的特性,矿物油阻止氧气从空气中流入。

在用荧光酶标仪根据细胞外氧浓度测量荧光强度之后,根据Stern-Volmer方程计算细胞的OCR(自动计算表)。

*该产品在群马大学Toshitada Yoshihara博士的指导下实现了产品化。

与现有方法比较

到目前为止,OCR测量需要昂贵的设备,如通量分析仪,实时动态检测酶标仪,以及酶标仪的功能调节。该试剂盒推荐给初此使用的人,因为它可以与常规荧光酶标仪一起使用,并附带所有必要试剂的完整包装。

细胞种类: HepG2

细胞数: 5×10⁴ cells/well

试剂: FCCP (Carbonyl cyanide 4-(trifluoromethoxy)phenylhydrazone)

FCCP 浓度: 2 μmol/l

实验例:抑制线粒体电子传输链

用抗霉素刺激大鼠细胞,评估线粒体电子运输链抑制后细胞状态的变化,检测多种指标。

结果表明,电子传输链的抑制导致(1)线粒体膜电位的降低和(2)OCR的降低。此外,观察到(3)整个糖酵解途径的NAD+/NADH比率降低,这是由于丙酮酸到乳酸的代谢增加,以维持糖酵解通路;(4)由于活性氧(ROS)增加,GSH耗竭;(6)由于谷胱甘肽生物合成所需NADPH减少,NADP+/NADPH比率增加。

实验例:不同细胞系代谢途径依赖性的比较

    许多癌症细胞通过糖酵解途径产生ATP。另一方面,最近有报道称,糖酵解途径被抑制的癌症细胞,可通过增强线粒体功能将能量代谢转移到OXPHOS而达到存活的目的,代谢途径的依赖性因细胞系不同而异。

基于乳酸生成、ATP水平和OCR值,比较了两种癌症细胞HeLa和HepG2中OXPHOS和糖酵解的依赖性关系。

<通过乳酸生产和ATP水平进行评估>

我们证实了当寡霉素刺激和糖酵解途径中的 2-Deoxy-D-glucose(2-DG)抑制OXPHOS的ATP合成时,ATP和乳酸产生的变化。结果表明,HeLa细胞依赖于糖酵解,HepG2细胞依赖于OXPHOS合成ATP。

*有关结果的更多信息,请参下方的“所用技术和产品的补充信息”部分。

所用技术和产品的补充信息
<通过乳酸产生和ATP的量进行评估>

当OXPHOS在HeLa细胞中被抑制时,ATP水平保持不变(①),乳酸产生增加(②)。这表明,即使OXPHOS被抑制,糖酵解也可以被进一步激活。相反,当糖酵解被抑制时,ATP水平显著降低(③),表明能量的产生依赖于糖酵解。另一方面,当OXPHOS在HepG2细胞中被抑制时,乳酸的产生增加(④),表明细胞试图通过增强糖酵解来补偿能量的产生,但ATP水平仍然降低(⑤)。这意味着,即使糖酵解增加,ATP的产生也没有得到足够的代偿。此外,当糖酵解被抑制时,ATP水平下降更多(⑥),这表明HepG2细胞的能量产生更多地依赖于OXPHOS而不是糖酵解。

本数据同时使用了:糖酵解/氧化磷酸化检测试剂盒—Glycolysis/OXPHOS Assay Kit(G270)

<OCR值评估>

使用相同数量的细胞,我们测量了当用线粒体解偶联剂FCCP刺激细胞来促进细胞耗氧量时的OCR值。结果表明,HepG2细胞比HeLa细胞具有更高的OCR值,这表明对OXPHOS的依赖性更强,这与ATP水平和乳酸产生的结果有关。

Q:如何使用此试剂盒计算OCR?
A:请使用Excel计算表并遵循以下说明

 

<OCR计算程序概述>

(1) 将OCR测量获得的强度值输入计算表,使用Stern-Volmer公式自动计算氧含量(nmol)。

(2) 根据时间(min)与氧含量(nmol)的关系图,检查所有测量条件下获得的线性范围。

(3) 计算步骤(2)中确认的时间(min)和氧含量(nmol)范围内的斜率。

(4) 根据步骤(3)中计算的斜率计算OCR(pmol/min)。

有关详细信息,请参阅手册中的“分析”。

*需要计算OCR的客户请至【网站首页】-【技术支持】-【实验工具】即可找到OCR计算器

 

Q:矿物油对细胞有细胞毒性吗?
A: 当通过Cell Counting Kit-8细胞毒性测定测定时,在用矿物油处理的细胞中未观察到毒性。

 

Q:为什么使用此试剂盒需要搭配可控温的酶标仪?
A: 在添加试剂和矿物油后,将微孔板与培养箱(或加热块、恒温室等)一起孵育,酶标仪中的温差将影响OCR结果。这导致数据再现性下降。因此,请使用温度可控的酶标仪。

Q:OCR检测后如何测量细胞数
A:使用核酸探针(代码:H342)Hoechst 33342测量每个孔的细胞数,这是该方案的一个示例。

<说明>

(1) 将细胞接种到孔中进行OCR测量(液体体积:100μl/孔)。

(2) 将制备校准曲线的细胞接种到孔中(液体体积:100μl/孔)。

(3) OCR根据说明书进行测量。

Q:可以长期存储工作液吗
A 工作液不能储存,需要现配现用。
Q:氧探针或矿物油的反复冷冻和解冻是否会影响测定?
A 我们已经证实,氧气探针和矿物油的反复冻融循环对测定没有影响。
Q:对照组与实验组之间OCR没有差异,有哪些可能得原因?
A请检查以下两个实验条件。

(1) 如果在测量过程中温度发生变化,可能会影响OCR结果。请确保以下两个步骤完全按照说明书执行。

・矿物油、溶剂和稀释溶剂等溶液在使用前应预热至37°C左右。

・加入试剂和矿物油后,请使用温度可控的酶标仪进行孵育。

请参阅Q&A“为什么使用此试剂盒需要搭配可控温的酶标仪?”。

(2) 建议在最终计算前,优化单元格数据。如果细胞数量较低,实验组和对照组之间的差异也可能并不显著。

Seed Bead™ Kits

Applications

  • Generate seeds of protein crystals

Features

  • Easily generate consistent seed stocks
  • Use serial dilution to control the number of seeds introduced into the drop
  • Microseed matrix screening (MMS) seed stock
  • PTFE, Stainless Steel, Zirconium Silicate Ceramic, or Glass Seed Bead

Description

The Seed Bead kits are used to create a seed stock for performing subsequent seeding experiments. The Seed Bead kits contains 24 Seed Bead Tubes, a special 1.5 ml microcentrifuge tube, shaped to maintain the seed in the sample during mixing. Each tube is configured with a PTFE, Stainless Steel, Zirconium Silicate Ceramic, or Glass Seed Beads.

Seeding allows one to grow crystals in the metastable zone. Crystallization in this zone provides control, reproducibility and an improved likelihood of a successful crystallization experiment. Also, crystals can grow from seeds but cannot spontaneously nucleate. By placing a seed or solution of seeds in a drop which is saturated to the metastable zone, one can use the seeds to grow larger single crystals. By controlling the number of seeds introduced into the drop, one can control the number of crystals grown. It is not practically possible to measure and know the number of seeds introduced to a drop, but by performing serial dilutions from a concentrated seed stock, one can control the number of crystals grown in the drop.

Using the Seed Bead kits, one can create crystal seed stock for subsequent seeding experiments. Crystals are placed in the microcentrifuge tube with the Seed Bead(s) and either vortexed or sonicated to generate a seed stock. Then by performing serial dilutions, one can control the number and size of crystals in the experiment.

The Seed Bead kit is useful for the preparation of seed stocks for automated and semi-automated microseeding (D’Arcy 2007, Harlos 2008).

Each Seed Bead Kit (HR2-320) contains 24 special microcentrifuge tubes, each tube containing a single 3mm PTFE Seed Bead.

Each Seed Bead Steel Kit (HR4-780) contains 24 special microcentrifuge tubes, each tube containing a six 1.6 mm Stainless Steel Seed Beads.

Each Seed Bead Ceramic Kit (HR4-781) contains 24 special microcentrifuge tubes, each tube containing a ten 1.0 mm Zirconium Silicate Ceramic Seed Beads.

Each Seed Bead Glass Kit (HR4-782) contains 24 special microcentrifuge tubes, each tube containing a ten 1.0 mm Glass Seed Beads.

LCP Sandwich Set

Applications

  • Crystallization screening of membrane proteins in lipidic mesophase as well as bicelle method and batch method

Features

  • Small volume LCP, bicelle and microbatch crystallization
  • High quality glass optics
  • Excellent drop optics since mesophase bolus is physically sandwiched between two optically clear surfaces eliminating the mesophase / aqueous medium interface and the corresponding roughness
  • Glass plate allows for visualization of microcrystals using birefringence-free examination between crossed polarizers
  • Superhydrophobic glass surfaces
  • Optimized for bright field, UV and fluorescent microscopy
  • Excellent stability, resistant to evaporation

Description

The LCP Sandwich Set consists of a base glass slide and an optimized cover slip. LCP Sandwich Set developed jointly with the renowned Scripps Research Institute in La Jolla, California, USA and is manufactured by Paul Marienfeld (0890003).

The LCP Glass Sandwich Set is a specially designed plate for either automated or manual setting of 96 Lipidic Cubic Phase matrix screening experiments. The plate can also be used for the bicelle method and batch method. The thin (< 2 mm high) plates have exquisite optical properties and are well suited for the detection of microcrystals and for birefringence-free imaging between crossed polarizers. The plates allow for in meso crystallization trials with 50 nanoliters protein/lipid mesophase and 1 microliter precipitant solution per trial.

The 96 well LCP Glass Sandwich Plate consists of a) 127.8 x 85.5 x 1 mm glass base plate with the footprint of an SBS-compliant plate, a 140 µm thick double sticky spacer with 96 punched out holes and b) a 0.2 mm thick glass coverslip. The double sticky spacer is already adhered to the base plate. A brown paper liner covers and protects the top of the double sticky spacer and base plate. The 0.2 mm thick glass coverslip fits over and seals the entire 96 well lower plate. Alternatively a series of twenty-four siliconized 18 x 18 mm No. 1 square cover slides (HR3-152) can be used to seal the entire 96 well lower plate. Each 18 x 18 mm No. 1 cover slide seals 4 wells. Space for a bar code is available at the left end of the plate. Each well can contain 50 nanoliters of cubic phase and 1 microliter of crystallization reagent.

18 x 18 mm No. 1 Siliconized Cover Slides are made from chemically resistant borosilicate glass D 263 M of the first hydrolytic class. The slides are colorless, clear, and suitable for fluorescence microscopy. The slides feature a super hydrophobic surface on both sides. The slides are No. thickness (0.13 ro 0.16 mm). The slides are supplied in a two compartment plastic box, 100 slides per box, 10 boxes per case, 1,000 slides total for HR3-152.

The Tungsten-carbide glass cutter can be used for cutting and removal of the upper coverglass that seals the LCP Sandwich Set. Sold separately.
