Sample preparation is a key step in proteomics workflows. Tube-gel (TG) is a fast and repeatable sample preparation method that consists in the instantaneous trapping of the sample in a polyacrylamide gel matrix. It takes advantage of in-gel sample preparations by allowing the use of high concentrations of sodium-dodecyl sulfate but avoids the time-consuming step of electrophoresis. Therefore, TG limits the sample handling and is thus particularly suitable for high-throughput quantitative proteomics when large sample numbers have to be processed, as it is often the case in biomarker research and clinical proteomics projects.
样品制备是蛋白质组学工作流程中的关键步骤。管凝胶(TG)是一种快速且可重复的样品制备方法,其原理是将样品瞬间捕获在聚丙烯酰胺凝胶基质中。它利用凝胶内样品制备方法,允许使用高浓度的十二烷基硫酸钠,但避免了耗时的电泳步骤。因此,TG减少了样品处理,特别适用于需要处理大量样品的高通量定量蛋白质组学,在生物标志物研究和临床蛋白质组学项目中经常如此。
