SWATH DIA (data independent acquisition) - SCIEX
SWATH DIA helps generate a permanent digital proteome map with highly reproducible retrospective analysis of cellular and tissue specimens. It combines quantitative reproducibility with the speed and sensitivity gains of modern mass spectrometers.
SWATH蛋白组学定量分析详解 - 知乎 - 知乎专栏
SWATH（Sequential Window Acquisition of all Theoretical fragment ions）是一项由ETH Zürich研究所的Dr. Ruedi Aebersold团队与AB SCIEX在2012年共同研发的一项全新的质谱采集模式技术。 SWATH最大的特点在于这项技术可以像Label-free技术一样不用标记样品，但检测精度却又远高于Label-free等技术，能够达到和MRM技术同一级别。 SWATH综合了shotgun proteomics高通量检测的特点与精准定量分析的优势，是真正意义上的全景质谱检测手段MS/MSALL。 SWATH之 …
SWATH-MS: Data Acquisition and Analysis - ScienceDirect
2016年1月1日 · SWATH-MS is a relatively novel mass-spectrometry-based approach that combines the strengths of DDA and DIA. DIA allows for precise quantification of proteins based on the area under the peak similar to multiple reaction monitoring (MRM) approach without the need for peptide labeling.
