Thermo Scientific Pierce TMT11plex 酵母消化标准品是使用 TMT11plex 试剂标记的四种同类系冻干酵母肽混合物,用于监测进行 Tandem Mass Tag (TMT) 定量测定的 LC-MS/MS 系统的性能。

Pierce TMT11plex 酵母消化标准品特点包括:
便利—使用即用型冻干式 TMT11plex 试剂预先标记
经过高度验证—验证酵母菌株的基因型、TMT-标记株的等摩尔混合以及使用 TMT 对总蛋白进行定量
诊断—用于 LC 和 MS 仪器状态质量评估的出色 QC 检测工具
定量—旨在测量 11 通道中每个通道的 TMT 报告离子的定量精度

使用 TMT 试剂的蛋白质组学定量策略使样品多通路和精确测量蛋白质丰度成为可能。然而,成功执行此工作流程包括可能需要优化的多个步骤,包括色谱、质谱 (MS) 和数据分析。成功完成该工作流程的一个关键参数是能够在多通路技术的 11 个通道中一致地检测到 TMT 片段离子。该标准品经专门设计作为监测 LC-MS/MS 系统(用于 TMT 定量和 MS 方法优化及校验)性能的工具。

Pierce TMT11plex 酵母消化标准品由四种基因品系的酿酒酵母(一种亲本菌株 BY4741 以及三种缺乏非必需蛋白 Met6、His4 或 Ura2 的菌株)组成,使用 TMT11-plex 标记试剂一式三份(敲除菌株)或两份(亲本菌株)标记(参见图)。敲除菌株与亲本菌株结合使用,可以比较缺失菌株和亲本菌株中的肽和蛋白丰度,从而监测系统性能,进行定量分析。

除了常规质量控制评估之外,该标准还可以作为一种方法开发工具,以测量不同 MS 方法的准确度、精确度和动态范围,包括优化离线分馏、色谱、MS 采集或数据分析设置。

本标准的多功能应用程序使日间至实验间 TMT 定量具有更高可重现性。

常见问题解答 (FAQ)

After running the Pierce TMT11plex Yeast Digest Standard, I observe low signal to noise ratio and poor quantitation accuracy for the Tandem Mass Tag (TMT) reporter ions. What do you recommend?

Here are some recommendations:

- Clean and recalibrate the mass spectrometry instrument using one of our Pierce Calibration Solutions (https://www.thermofisher.com/search/browse/category/us/en/600654).
- Verify settings for liquid chromatography (LC) acquisition methods.
- Fractionate TMT-labeled samples using the Pierce High pH Reversed-Phase Peptide Fractionation Kit (Cat. No. 84868) to reduce sample complexity.

How do I use the Pierce TMT11plex Yeast Digest Standard to optimize my LC-MS acquisition parameters?

The Pierce TMT11plex Yeast Digest Standard (i.e., TKO standard) is a lyophilized yeast peptide mixture of four congenic strains labeled with TMT11plex reagents. It can be used to rapidly and accurately assess ion interference (co-isolation of multiple analytes of similar mass-to-charge) for TMT-based quantitative mass spectrometry proteomic analysis.

Which standard do you recommend using for Tandem Mass Tag (TMT) workflows?

We recommend using our Pierce TMT11plex Yeast Digest Standard (Cat. Nos. A40938, A40939) for LC-MS method optimization and for assessing system suitability for TMT-labeled samples.

Which standards and calibrants do you recommend using for assessing LC-MS system suitability?

Here are our recommendations:

- Pierce Peptide Retention Time Calibration Mixture (Cat. No. 88321) for LC system and gradient optimization
- Pierce BSA Protein Digest, MS grade (Cat. No. 88341), Pierce 6 Protein Digest, equimolar, LC-MS grade (Cat. No. 88342), and Pierce HeLa Protein Digest Standard (Cat. Nos. 88328, 88329) for "bottom up" LC-MS method optimization and LC-MS suitability assessment
- Pierce LC-MS/MS System Suitability Standard (7 x 5 Mix) (Cat. No. A40010) for assessing the gradient, sensitivity, and dynamic range of the LC-MS system for discovery and targeted peptide quantitative workflows
- Pierce TMT11plex Yeast Digest Standard (Cat. Nos. A40938, A40939) for assessing system performance for TMT-based quantitative workflows
- Pierce Intact Protein Standard Mix (Cat. Nos. A33526, A33527) for "top down" LC-MS method optimization and LC-MS suitability assessment

What type of mass spectrometer can I use for Tandem Mass Tag (TMT) analysis?

We recommend using high-resolution Orbitrap Tribrid (e.g., Fusion, Lumos, Eclipse), Orbitrap Exploris (e.g., 240, 480), or Q Exactive (e.g,. Plus, HF, HFX) series of instruments.
