Thermo Scientific Pierceペプチド脱塩スピンカラムは、酵素消化後のペプチドサンプルの脱塩を効率的に行える、すぐに使用可能な遠心スピンカラムです。各カラムに含まれるポリマーベースの疎水性レジンは、質量分析やその他のメソッド用の調製において、ペプチドサンプルの優れた結合および回収特性を提供します。

Pierceペプチド脱塩スピンカラムの特長:
MS効率を低下するコンタミ成分を除去 — シグナル抑制を大幅に抑え、質量分析における感度を向上させます
高い結合キャパシティー—特殊な疎水性ポリマーベースレジンにより、5 µgのペプチドから最大5 mgの天然およびTMT標識ペプチドまで、優れた回収率を実現します
使いやすい — レジンは、多くの一般的な2 mL チューブに適合するシングルユーススピンカラムフォーマットで提供されています
適合性 — レジンは、TMT標識ペプチドなどのさまざまな複雑なサンプルで検証済みで、極端なpH条件下でも安定しています

Pierceペプチド脱塩スピンカラムを使用すると、便利で再現性のある方法により、質量分析の前にペプチドサンプルから脱塩および汚染物質を除去できます。各スピンカラムは、5 µg~5 mgの天然およびTMT標識ペプチドを結合できます。スピンカラムフォーマットのため、約30分で複数のサンプル(各10~300 µL)を並行処理できます。

質量分析は、生体化合物の研究に不可欠です。しかし、サンプル調製の過程で使用されるバッファーや試薬の多くは質量分析の妨げとなり、スペクトルの質の低下や感度の低下を招きます。Pierceペプチド脱塩スピンカラムは、サンプルロスを最小限に抑えながら多くの疎水性サンプル汚染物質を除去するように設計されているため、質量分析による消化タンパク質サンプルの高感度かつ包括的な分析が可能です。

よくあるご質問(FAQ)

How do I determine if my sample is compatible and ready for LC-MS?

Samples prepared using LC/MS grade reagents are suitable for LC-MS; however, particulates and other small molecules can all interfere with liquid chromatography separation and mass spectrometer source ionization. We recommend visual inspection of samples for particulate matter and using Pierce Peptide Desalting Spin Columns (Cat. Nos. 89851, 89852), Pierce C18 Spin Tips (Cat. No. 84850) or an in-line C18 trap column (https://www.thermofisher.com/order/catalog/product/164564-CMD) to remove non-volatile salts before MS analysis.

After TMT reagent labeling, I still see a lot of excess TMT tags in my sample. How should I remove it?

We offer EasyPep MS sample preparation kits (EasyPep Maxi Sample Prep Kit (Cat. No. A45734), EasyPep Mini MS Sample Prep Kit (Cat. No. A40006), EasyPep 96 MS Sample Prep Kit (Cat. No. A45733)) that contain wash buffers specifically formulated to clean up TMT-labeled protein digests. To remove excess TMT reagent from samples prepared using other sample preparation methods, we recommend using Pierce Peptide Desalting Spin Columns (Cat. Nos. 89851, 89852) with extra washes using 5% methanol. The Pierce High pH Reversed-Phase Peptide Fractionation Kit (Cat. No. 84868) can also be used to remove excess unreacted TMT tags before collecting fractions.

I'm seeing a peak in my mass spectrometry analysis results that seems to always be present in my system. What can I do?

The peak most likely represents PEG or a similar contaminant. Clean your MS system and/or perform sample clean-up using Pierce Peptide Desalting Spin Columns (Cat. Nos. 89851, 89852) or Pierce C18 Resin. In addition, ensure that LC-MS pre-blended solvents are being used (formic acid/water, formic acid/acetonitrile, etc.)

I cleaned up my peptide sample using C18 or desalting columns, but I lost most of my peptides. What went wrong?

Peptides do not bind well to reversed phase resins at neutral pH or in the presence of organic solvents (e.g., acetonitrile). Acidify protein digest samples using formic acid or trifluoroacetic acid (TFA) to pH <3 before desalting. Ensure that samples do not contain organic solvents before and after clean-up by drying them down using a SpeedVac concentrator or equivalent.

If I already removed small contaminants and detergents at the protein level, do I still need to desalt my peptides prior to mass spectrometry analysis?

Yes. We recommend performing additional cleanup after protein digestion to remove any residual salts or partially digested proteins using Pierce Peptide Desalting Spin Columns (Cat. Nos. 89851, 89852), Pierce C18 Spin Tips (Cat. No. 84850) or an in-line C18 trap column (https://www.thermofisher.com/order/catalog/product/164564-CMD).

Integrating cross-linking mass spectrometry (XL-MS) into structural biology workflows provides valuable information about the spatial arrangement of amino acid stretches, which can guide elucidation of protein assembly architecture. Additionally, the combination of XL-MS with peptide quantitation techniques is a powerful approach to delineate protein interface dynamics across diverse conditions. While ... More

Multiplexed proteomics using isobaric tagging allows for simultaneously comparing the proteomes of multiple samples. In this technique, digested peptides from each sample are labeled with a chemical tag prior to pooling sample for LC-MS/MS with nanoflow chromatography (NanoLC). The isobaric nature of the tag prevents deconvolution of samples until fragmentation ... More
