以所有理论质谱的连续窗口采集(SWATH-MS)为例的数据独立分析(DIA)提供了稳健的定量蛋白质组学数据,但缺乏公共的原代人类T细胞谱库是当前的资源缺口。在这里,我们报告了一个高质量的光谱库的生成,其中包含来自遗传无关供体的人类T细胞的4,833种不同蛋白质的数据,覆盖了UniProt/SwissProt审查的人类蛋白质组的约24%。使用新的人类T细胞光谱库对18个原代T细胞样本进行SWATH-MS分析,以1%的错误发现率(FDR)可靠地鉴定和定量了2,850种蛋白质。相比之下,更大的泛人类光谱库在同一数据集中识别和定量了2,794种T细胞蛋白。由于文库鉴定了一组重叠的蛋白质,因此将两个文库组合导致4,078种人类T细胞蛋白质的定量。总的来说,这个大型数据档案将成为人类T细胞蛋白质组学研究的有用公共资源。人T细胞文库可在SWATHTlas获得,数据可通过ProteomeXchange(PXD 019446和PXD 019542)和PeptideAtlas(PASS 01587)获得。描述报告数据的机器可访问元数据文件:10.6084/m9.figshare.12991619
Data independent analysis (DIA) exemplified by sequential window acquisition of all theoretical mass spectra (SWATH-MS) provides robust quantitative proteomics data, but the lack of a public primary human T-cell spectral library is a current resource gap. Here, we report the generation of a high-quality spectral library containing data for 4,833 distinct proteins from human T-cells across genetically unrelated donors, covering ~24% proteins of the UniProt/SwissProt reviewed human proteome. SWATH-MS analysis of 18 primary T-cell samples using the new human T-cell spectral library reliably identified and quantified 2,850 proteins at 1% false discovery rate (FDR). In comparison, the larger Pan-human spectral library identified and quantified 2,794 T-cell proteins in the same dataset. As the libraries identified an overlapping set of proteins, combining the two libraries resulted in quantification of 4,078 human T-cell proteins. Collectively, this large data archive will be a useful public resource for human T-cell proteomic studies. The human T-cell library is available at SWATHAtlas and the data are available via ProteomeXchange (PXD019446 and PXD019542) and PeptideAtlas (PASS01587).
