We present an in-depth analysis of mouse plasma leading to the development of a publicly available repository composed of 568 liquid chromatography-tandem mass spectrometry runs. A total of 13,779 distinct peptides have been identified with high confidence. The corresponding approximately 3,000 proteins are estimated to span a 7 logarithmic range of abundance in plasma. A major finding from this study is the identification of novel isoforms and transcript variants not previously predicted from genome analysis.
我们对小鼠血浆进行了深入分析,从而开发出一个公开可用的数据库,该数据库由568次液相色谱-串联质谱分析组成。总共已高可信度地鉴定出13779种不同的肽段。据估计,相应的约3000种蛋白质在血浆中的丰度跨越7个对数范围。这项研究的一个主要发现是鉴定出了以前基因组分析未预测到的新型异构体和转录变体。
