摘要
电喷雾串联质谱测序法是蛋白质组研究中蛋白质鉴定的最有力的手段之一.肽段离子在ESI-Q-TOF中往往以多电荷形式出现(2~4个电荷),其中m/z在500~1000之间带双电荷的离子最适合测序.……
Sequence analysis of peptides with sodium adduct is very important for protein identification. Five peptides with sodium adduct were sequenced by nano-ESI-MS - MS and the sequences were analyzed. S, P and Y are the amino acids which add sodium ion.
