概述

总谷胱甘肽(T-GSH)包括还原型(GSH)和氧化型(GSSG)谷胱甘肽。GSSG 又称为二硫代谷胱甘肽, 由两分子的还原型谷胱甘肽氧化而成。谷胱甘肽能帮助保持正常的免疫系统功能,并具有抗氧化作用、整合解毒 作用。GSSG 会被谷胱甘肽还原酶还原成 GSH,因此机体中大多数是以还原型形式存在。测定细胞内 GSH 和 GSSG 含量以及 GSH/GSSG 比值,能够很好地反映细胞所处的氧化还原状态,也是谷胱甘肽氧化还原循环的主 要指标之一。 

本试剂盒检测原理是使用适当的封闭剂抑制样品中原有的还原型谷胱甘肽,然后利用谷胱甘肽还原酶 (Glutathione reductase,GR)将 GSSG 还原为 GSH,GSH 与 5,5-二硫双(2-硝基苯甲酸)(DTNB)反应生 成 2-硝基-5-巯基苯甲酸,反应液呈黄色,测定其在 412 nm 处的吸光度值的变化即可计算样本中 GSSG 的含量。

样本制备:

注意:推荐使用新鲜样本,如果不立即进行实验,样本可在-80℃保存 30 天。因 提取缓冲液中含有蛋白质沉淀剂,因此上清液不能直接用于蛋白浓度测定。如需测定蛋白含量,需另取相同样本,把提取缓冲液换成去离子水提取制备。本试剂盒涉及氧化还原反应,具有还原或氧化特性的试剂比如 DTT、TCEP、β-巯基乙 醇、铁离子、半胱氨酸等会干扰反应,另外 Tris 也会影响检测,因此在样本制备过程中应避免使用含有这些物质的试剂。推荐使用氧化锆研磨珠研磨样本,超声破碎前检查探头是否生锈。 

1. 动植物组织样本:请尽量使用新鲜的组织样本进行测定。称取 0.1 g 组织样本,加入 1 mL 预冷的提取缓冲液,快速冰上匀浆(匀浆器提前放冰上预冷)。匀浆后的样本,4℃,8000 g 离心 10 min,取上清液置 冰上待测。 

2. 血清(浆)样本:请尽量使用新鲜的血清(浆)进行测定。取 60 µL 血清(浆),加入 3 倍体积的提取缓冲液,室温静置 5 min,4℃,8000 g 离心 10 min,取上清液置冰上待测。

3. 细胞(菌)样本:请尽量使用新鲜的细胞(菌)进行测定,而不要使用冻存的细胞(菌)进行测定。收集 5×10 6个细胞(菌),用 1 mL 预冷的 PBS 清洗细胞(菌)2 次(PBS 重悬,4℃,600 g 离心 10 min), 加入 1 mL 提取缓冲液重悬细胞(菌),冰浴超声波破碎 5 min(功率 20%或 200W,超声 3 s,间隔 7s,重复 30 次),4℃,8000 g 离心 10 min,取上清液置冰上待测。细胞也可以使用冻融法提取,重悬的细胞反复快速冻融 2-3 次(在液氮中冻结,37℃水浴中溶解),4℃,8000 g 离心 10 min,取上清液置冰 上待测。 

4. 全血样本:请尽量使用新鲜的全血样本进行测定。取 60 µL 全血样本,加入 3 倍体积的提取缓冲液, 快速冰上匀浆(匀浆器提前放冰上预冷),匀浆后的样本,4℃,8000 g 离心 10 min,液体表层可能会出现一层“血膜”,为避免“血膜”干扰,取上清 4℃,8000 g 再离心 1 min,取上清液置冰上待测。 

5. 红细胞样本:将抗凝管收集的血液 4℃,1000 g 离心 10 min。弃去上层血浆及白细胞层,用 5 倍体积预冷 的 PBS 清洗红细胞 2 次,4℃,1000 g 离心 10 min,取 100 µL 红细胞加入 0.3 mL 提取缓冲液,快速冰上匀浆或者研磨、超声破碎,参考上述样本破碎方法,4℃,8000 g 离心 10 min,取上清液置冰上待测。

实验步骤:

1. 酶标仪准备:预热 30 min 以上,调节波长到 412 nm。

2. 抑制剂工作液的配制:临用前配制,现配现用。对于 96 孔板,每孔配制 160.5 µL 抑制剂工作液。吸取 0.5 µL 抑制剂,160 µL 检测缓冲液,充分混匀。 

酶促工作液的配制:临用前配制,现配现用。对于 96 孔板,每孔配制 22 µL 酶促工作液。吸取 0.4 µL 酶,1.6 µL 检测缓冲液 ,20 µL 谷胱甘肽还原酶辅因子工作液,充分混匀。

注意:酶需混匀后再取用。  

3. 检测体系配制:在 96 孔板中按照如下方式操作:

试剂空白孔 (μL)标准孔 (μL)测定孔 (μL)
样本0020
氧化型谷胱甘肽标准品0200
提取缓冲液2000
抑制剂工作液160160160
酶促工作液222222
显色底物202020
注意: 抑制剂工作液加入混匀后 37℃避光孵育 30 min,然后依次加入酶促工作液和显色底物。

注意:因反应迅速,建议单独做标准曲线,并从低浓度到高浓度的顺序向标准品中添加显色底物。检测样本时, 在 5 min 内完成全部加样操作不会影响检测结果。

4. 吸光度检测:充分混匀后立即在 412 nm 处读取吸光度值 A1,分别标记为 A1 空白、A1 标准和 A1 测定,室温(25℃)避光孵育 5 min 后,立即在 412 nm 处读取吸光度值 A2,分别标记为 A2 空白、A2 标准和 A2 测定。

结果计算:

以下为您提供的推导过程计算公式和简洁计算公式,两者完全相等。

1.数据处理

计算 ΔA=A2−A1,ΔΔA标准=ΔA标准−ΔA空白,ΔΔA测定=ΔA测定−ΔA空白。

 2.标准曲线绘制 以标准品浓度为 y 轴,ΔΔA标准为 x 轴,绘制标准曲线。将 ΔΔA测定代入方程得到 y 值(µM)。 

3.样本 GSSG 计算 

按样本质量计算

 GSSG (nmol/g)=y×V样÷(W×V样÷V提取)×n=y÷W×n 

按细胞或细菌数量计算

 GSSG (nmol/104)=y×V样÷(N×÷V提取)×n=y÷N×n 

按液体体积计算 

GSSG (nmol/mL)=y×V样÷(V样÷V2×V1)×n=4y×n 

按蛋白浓度计算 

GSSG (nmol/mg prot)=y×V样÷(V样×Cpr)×n=y÷Cpr×n nmol:1μM=1nmol/mL;

V样:加入样本体积,20μL;

V提取:加入Extraction Buffer体积,1mL;

V1:提取时加入的液体样本体积;

V2:液体样本提取时的总体积(加入的提取液体积为3V1,V2=4V1);

W:样本质量,g;

n:样本稀释倍数;

Cpr:样本蛋白质浓度,mg/mL;

N:细胞或细菌数量,以10⁴为单位(例如细胞数量为5×10⁶,N=500)。

结果展示:

典型标准曲线:y=30.554x+0.7721,R²=0.9973

示例:取 0.1 g 兔脑组织,检测时不稀释(n=1),按照测定步骤操作,采用 96 孔板检测。测得:ΔA测定=A2 测定−A1 测定=0.2510−0.1067=0.1443,ΔA空白=A2 空白−A1 空白=0.0877−0.0863=0.0013,ΔΔA测定=ΔA测定−ΔA空白=0.1443−0.0013=0.1430。将 ΔΔA测定代入标准曲线方程,得到 y=5.141。按样本质量计算: GSSG (nmol/g)=y÷W×n=5.141÷0.1×1=51.41 nmol/g。

常见问题:

检测得到的样本 ΔΔA测定过高或者过低怎么办?

如果样本的ΔΔA测定大于标准品最高浓度的 ΔΔA标准,则说明样本 GSSG 含量太高,需用提取液适当稀释(计算公式中乘以相应稀释倍数);如果样本的 ΔΔA测定小于标准品最低浓度的 ΔΔA标准,可提高样本量或者减少提取液体积。

  Glutathione is a tripeptide containing a γ-amide bond and a sulfhydryl group, composed of glutamate, cysteine, and glycine. It is widely found in animal and plant tissues and microorganisms. In living organisms, it helps maintain normal immune system function and has antioxidant and detoxifying effects. Glutathione exists in two forms: reduced (GSH) and oxidized (GSSG). GSSG, also known as glutathione disulfide, is formed by the oxidation of two glutathione molecules. GSSG can be reduced back to GSH by glutathione reductase; therefore, it exists primarily in the reduced form in organisms. The ratio of reduced to oxidized glutathione (GSH/GSSG) serves as a key dynamic indicator for assessing the cellular redox state.

  Detection Principle: Endogenous GSH in the sample is masked by 2-vinylpyridine. Under the catalysis of glutathione reductase (GR), GSSG is reduced to GSH. The generated GSH then reacts with 5,5'-Dithiobis-(2-nitrobenzoic acid) (DTNB) to produce yellow-colored 5-thio-2-nitrobenzoic acid (TNB), which has a characteristic absorption peak at 412 nm. The GSSG content is quantified by measuring the change in absorbance.

  Detection Range: 1-20 µM

  Sensitivity: 1 µM

  Applicable Samples: Animal/plant tissues, blood cells, cells, bacteria, serum (plasma).

3. Sample Preparation

Note: Fresh samples are recommended. If not used immediately, samples can be stored at -80°C for up to 10 days. Because the Extraction Buffer contains a protein precipitant, the supernatant cannot be used for protein concentration determination. If protein content needs to be measured, prepare another identical sample using deionized water instead of Extraction Buffer.

3.1 Animal/Plant Tissue Samples:

Use fresh tissue samples whenever possible. Weigh 0.1 g of tissue, add 1 mL of pre-cooled Extraction Buffer, and homogenize quickly on ice (pre-cool the homogenizer on ice). Centrifuge the homogenate at 8000 g, 4°C for 10 min. Collect the supernatant and keep on ice for detection.

3.2 Serum/Plasma Samples:

Use fresh serum (plasma) whenever possible. Centrifuge the collected serum (plasma) at 600 g, 4°C for 10 min. Within 30 minutes, aspirate the supernatant into another tube. Add an equal volume of Extraction Buffer, mix, then centrifuge at 8000 g, 4°C for 10 min. Collect the supernatant and keep on ice for detection.

3.3 Cell or Bacterial Samples:

Use fresh cells (bacteria) whenever possible; avoid using frozen cells (bacteria). Collect 5×10⁶ cells (bacteria). Wash twice with 1 mL of pre-cooled PBS (resuspend in PBS, centrifuge at 600 g, 4°C for 10 min). Add 3 times the volume of Extraction Buffer relative to the cell (bacterial) pellet to resuspend the cells (bacteria). Disrupt by ultrasound on ice (power 20% or 200 W, ultrasonicate for 3 s, interval 7 s, repeat 30 times). Centrifuge at 8000 g, 4°C for 10 min. Collect the supernatant and keep on ice for detection.

Note: Cells can also be extracted using a freeze-thaw method (not suitable for bacteria): Resuspend cells and subject to 2-3 rapid freeze-thaw cycles (freeze in liquid nitrogen, thaw in a 37°C water bath). Centrifuge at 8000 g, 4°C for 10 min. Collect the supernatant and keep on ice for detection.

4. Assay Steps

4.1 Microplate Reader Preparation: Preheat for at least 30 minutes, set wavelength to 412 nm.

4.2 Assay System Setup (Step 1 - Pre-treatment): Perform the following operations in 1.5 mL EP tubes. This step must be done in EP tubes. Do not add Inhibitor directly to the 96-well plate as it may corrode the plate. Inhibitor is toxic and irritant; recommended to handle in a fume hood.

5. Result Calculation The following provides both the derived formula and the simplified calculation formula, which are completely equivalent. 
5.1 Data Processing 
Calculate ΔA = A2 - A1 for each. 
Then calculate ΔΔA standard = ΔA standard - ΔA blank And ΔΔA test = ΔA test - ΔA blank 
5.2 Standard Curve Plotting 
5.2 Standard Curve Plotting Plot the standard curve with standard concentration as the y-axis and ΔΔA standard as the x-axis. Substitute ΔΔA test into the equation to obtain the y value (µM). 
5.3 Sample GSSG Content Calculation 
(1) Based on sample mass: GSSG (nmol/g) = y × V standard ÷ V sample × V extract ÷ W × n = 10 × y ÷ W × n 
(2) Based on cell or bacterial count: GSSG (nmol/10⁴) = y × V standard ÷ V sample × V extract ÷ 500 × n = 0.02 × y × V extract × n 
(3) Based on liquid volume: GSSG (nmol/mL) = y × V standard ÷ V sample × 2 × n = 20 × y × n 
(4) Based on protein concentration: GSSG (nmol/mg prot) = y × V standard ÷ V sample ÷ Cpr × n = 10 × y ÷ Cpr × n 
Parameter Description: 
1 µM = 1 nmol/mL; 
V standard : Volume of standard added, 30 µL; 
V sample : Volume of sample added, 3 µL; 
V extract : Volume of Extraction Buffer added, 1 mL (for cells/bacteria, use the actual volume used); 
W: Sample mass, g; 
n: Sample dilution factor; 
Cpr: Sample protein concentration, mg/mL; 
500: Cell or bacterial count, in units of 10⁴; 
2: Dilution factor for liquid samples (added equal volume of Extraction Buffer).
6. Result Presentation
Typical Standard Curve: y = 8.0042x + 0.212, R² = 0.9997
Example-1: 0.1 g of rat liver tissue was processed and assayed according to the procedure using a 96-well plate. 
Measured: ΔA test = A2 test - A1 test = 0.386 - 0.120 = 0.266 ΔA blank = A2 blank - A1 blank = 0.132 - 0.097 = 0.035 
ΔΔA test = ΔA test - ΔA blank = 0.266 - 0.035 = 0.231 
Substituting ΔΔA test into the standard curve equation gives y = 2.061 µM. 
Calculated based on sample mass: 
GSSG (nmol/g) = y × V standard ÷ V sample × V extract ÷ W × n = 10 × y ÷ W × n = 206.1 nmol/g.

Precautions

1. It is recommended to perform preliminary experiments using 2-3 samples expected to have significant differences before formal testing.

2. The samples extracted with this kit are suitable for the detection of oxidized glutathione (GSSG). Because the extraction buffer contains a protein precipitant, the supernatant cannot be used for protein concentration determination. If protein content needs to be measured, prepare another identical sample using deionized water instead of the extraction buffer. For protein concentration determination, Aladdin BCA Protein Quantification Kit (B665595) or Ready-to-Use BCA Protein Quantification Kit (R1491648) are recommended.

3. This kit is compatible with spectrophotometer detection. Adjust the preparation volume of detection reagents proportionally according to the spectrophotometer's requirements.

4. It is recommended to establish your own standard curve for improved accuracy. If not, you may refer to the typical standard curve formula provided in the results section for calculation.

5. Biochemical reagents are generally irritating and biologically toxic. For your safety and health, please wear appropriate personal protective equipment (lab coat, mask, gloves, hair cap, etc.) throughout the experiment and perform experiments in a fume hood or biosafety cabinet.

6. This product is for scientific research use only. Not intended for clinical diagnosis.

Frequently Asked Questions 

Q: What should I do if the sample ΔA test is too high or too low? 

Frequently Asked Questions Q: What should I do if the sample ΔA test is too high or too low? A: If the sample ΔA test is greater than the ΔA standard of the 20 µM standard, the GSSG content in the sample is too high. Dilute the sample appropriately with deionized water (multiply by the dilution factor in the calculation). If the sample ΔA test is less than 0.005, increase the sample amount.

Q: Can blood cell samples be detected?

A: Yes, blood cell samples can be detected. Centrifuge the collected anticoagulated blood at 600 g, 4°C for 10 min. Discard the upper plasma and wash the pellet 2-3 times with 3 volumes of PBS (resuspend blood cells in PBS, centrifuge at 600 g, 4°C for 10 min). Add an equal volume of Extraction Buffer, mix, and let stand at 4°C for 10 min. Centrifuge at 8000 g, 4°C for 10 min. Collect the supernatant and keep on ice for detection.
