The quantitative measurement of the proteome has been shown to yield new insights into physiology and cell biology that cannot be determined from the genome and transcriptome because the quantitative relationship between transcriptome and proteome is complex. MS-based proteomics techniques, such as SWATH-MS, have recently advanced to the point at which they may be reliably applied by biologists who are not specialists in mass spectrometry. Here we provide standard protocols for preparation of tissue samples for input into the SWATH-MS analytical pipeline. These protocols are designed for high-throughput processing of tissues with ≥5 mg of sample available for analysis. Studies with extremely limited amounts of tissue should consider PCT-SWATH. An experienced single user should be able to process 48 samples per day for injection into the mass spectrometer, or up to 144 samples a week. The machine time necessary for running these samples with SWATH is approximately 1.5 hr per sample. Data acquisition protocols are also provided. © 2017 by John Wiley & Sons, Inc.
蛋白质组的定量测量已被证明能为生理学和细胞生物学带来新的见解,而这些见解无法从基因组和转录组中确定,因为转录组和蛋白质组之间的定量关系很复杂。基于质谱的蛋白质组学技术,如SWATH-MS,最近已发展到非质谱专家的生物学家也可可靠应用的程度。在此,我们提供了用于制备组织样本以输入SWATH-MS分析流程的标准方案。这些方案设计用于对有≥5毫克样本可供分析的组织进行高通量处理。对于组织量极少的研究应考虑PCT-SWATH。一位经验丰富的单人用户每天应能够处理48个样本以供注入质谱仪,或每周最多处理144个样本。使用SWATH运行这些样本所需的机器时间约为每个样本1.5小时。还提供了数据采集方案。© 2017约翰威立父子公司版权所有
