Peak pairs with a mass difference of 14 Da were identified as N-terminal peptides while the internal peptides were single peaks and the ratios of their peak intensity were calculated for relative quantification of proteins.
标记后的蛋白质的N端肽以相差14 Da的成对峰形式在质谱中出现,而非N-末端肽则是以单峰呈现,从而实现了末端肽的特异性识别;通过端肽的信号强度对3种标记蛋白质的不同比例的混合溶液实现了相对定量分析。
