Abstract | 本发明提供了一种高通量集成化磷酸化蛋白组学检测方法,通过将连接在链霉亲和素板上的探针与诱饵蛋白形成捕获骨架,对酪氨酸磷酸化蛋白复合物进行富集捕获,酶解得到多肽,实现减少100倍探针用量的条件下300倍灵敏度的提升。利用150μm内径自填色谱柱高效液相色谱实现短梯度快速分离,结合Q Extractive HF‑X质谱仪在DIA数据采集模式下进行高效检测,可在不损失定性与定量检测性能条件下,实现单个样品35min内分离检测。实现了对不同EGF刺激时间下与不同浓度抑制剂作用下细胞中相关信号通路蛋白磷酸化条件瞬时变化的鉴定。为酪氨酸磷酸化蛋白质复合物的富集与鉴定提供了高通量、高灵敏、快速的检测方法。 |
Other Abstract | The invention provides a high-flux integrated phosphorylated proteomics detection method. A capture skeleton is formed by a probe connected to a streptavidin plate and bait protein, a tyrosine phosphorylated protein compound is enriched, captured and subjected to enzymolysis to obtain polypeptide, and the sensitivity is improved by 300 times under the condition that the use amount of the probe isreduced by 100 times. Short-gradient rapid separation is realized by utilizing high performance liquid chromatography of a self-filling chromatographic column with the inner diameter of 150 microns; efficient detection is carried out in a DIA data acquisition mode by combining a Q Extractive HF-X mass spectrometer, and separation and detection of a single sample within 35 minutes can be realized under the condition of not losing qualitative and quantitative detection performance. Identification of transient changes of phosphorylation conditions of related signal channel proteins in cells underthe action of inhibitors with different concentrations in different EGF stimulation time is realized. And a high-flux, high-sensitivity and rapid detection method is provided for enrichment and identification of the tyrosine phosphorylated protein compound. |
