MS-based proteomics has become an indispensable tool in system biology generating a need for accurate and precise quantitation of peptide standards. The presented method utilizes ultra performance LC-MS/MS (UPLC-MS/MS) to accurately quantify peptide standards at concentrations of 0.1-10 microM. The ability for accurate quantitation of micro-molar concentrations has the advantages that quantitation can be performed routinely with high precision and the high sensitivity of the method minimizes the amounts required.
基于质谱的蛋白质组学已成为系统生物学中不可或缺的工具，这就需要对肽标准品进行准确且精确的定量。本文所提出的方法利用超高效液相色谱-串联质谱（UPLC-MS/MS）对浓度为0.1-10微摩尔的肽标准品进行准确定量。对微摩尔浓度进行准确定量的能力具有以下优势：定量可常规高精度地进行，且该方法的高灵敏度使所需量最小化。
