提出了一种简单且可扩展的方法,用于哺乳动物质膜囊泡 (PMV) 的收获、纯化和芯片处理,并针对下游蛋白质组分析进行了优化。固定在 PMV 的微流体流通池上后,嵌入的膜蛋白被蛋白水解消化,收获肽并通过 LC-MS/MS 进行分析。超过 93% 的检测到的蛋白质是质膜衍生的。
A simple and scalable methodis presented for harvesting, purification, and on‐chip processing of mammalian plasma membrane vesicles (PMVs) optimized for downstream proteome analysis. After immobilization on a microfluidic flowcell of PMVs, the embedded membrane proteins are proteolytically digested, and the peptides harvested and analyzed by LC‐MS/MS. Over 93 % of the detected proteins are plasma‐membrane‐derived.
