AYeastSecretionTrapAssayforIdentificationofSecretedProteins...
Secreted proteins from plants and phytopathogens play important roles in their interactions and contribute to elaborate mechanisms of attack, defense, and counter-defense, as well as surveillance and signaling. There is therefore considerable interest in developing techniques to characterize “secretomes.” Here, we describe the use of the yeast secretion trap (YST) functional screen to isolate and identify s......阅读全文

离子阱质谱仪（Ion－trap，IT）
A：离子产物扫描法（Production scanning）是蛋白质组学研究里最常用的MS/MS质谱检测策略。该方法的目的就是要获得蛋白质片段离子的质谱图，然后据此鉴定出蛋白质的氨基酸序列。在本试验中，第一个质谱仪MS1是用来筛选出某一特定的母离子。随后，被选出的母离子在碰撞池中经由碰撞诱导解离作用
离子阱质谱仪（Ion－trap，IT）
在离子阱质谱仪中，可以捕获离子，因此也可以积累离子。离子阱技术具有无法比拟的高灵敏度和快速数据采集能力。将离子阱技术与数据依赖性采集技术（data-dependent acquisition）结合起来，我们就能进行高通量的质谱检测。不过，离子阱质谱仪的分辨率有限，捕获离子的能力不高，再加上空间电荷效
