Abstract

Matrices are necessary materials for ionizing analytes in matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS). The choice of a matrix appropriate for each analyte controls the analyses. Thus, in some cases, development or improvement of matrices can become a tool for solving problems. This paper reviews MALDI matrix research that the author has conducted in the recent decade. It describes glycopeptide, carbohydrate, or phosphopeptide analyses using 2,5-dihydroxybenzoic acid (2,5-DHB), 1,1,3,3-tetramethylguanidinium (TMG) salts of p-coumaric acid (CA) (G3CA), 3-aminoquinoline (3-AQ)/α-cyano-4-hydroxycinnamic acid (CHCA) (3-AQ/CHCA) or 3-AQ/CA and gengeral peptide, peptide containing disulfide bonds or hydrophobic peptide analyses using butylamine salt of CHCA (CHCAB), 1,5-diaminonaphthalene (1,5-DAN), octyl 2,5-dihydroxybenzoate (alkylated dihydroxybenzoate, ADHB), or 1-(2,4,6-trihydroxyphenyl)octan-1-one (alkylated trihydroxyacetophenone, ATHAP).

摘要

基质是基质辅助激光解吸/电离质谱(MALDI-MS)中使分析物离子化的必要材料。为每种分析物选择合适的基质可控制分析过程。因此,在某些情况下,基质的开发或改进可成为解决问题的一种手段。本文综述了作者在近十年中开展的MALDI基质研究。它描述了使用2,5-二羟基苯甲酸(2,5-DHB)、对香豆酸(CA)的1,1,3,3-四甲基胍盐(TMG)(G3CA)、3-氨基喹啉(3-AQ)/α-氰基-4-羟基肉桂酸(CHCA)(3-AQ/CHCA)或3-AQ/CA进行糖肽、碳水化合物或磷酸肽分析,以及使用CHCA的丁胺盐(CHCAB)、1,5-二氨基萘(1,5-DAN)、辛基2,5-二羟基苯甲酸酯(烷基化二羟基苯甲酸酯,ADHB)或1-(2,4,6-三羟基苯基)辛-1-酮(烷基化三羟基苯乙酮,ATHAP)进行一般肽、含二硫键的肽或疏水肽分析。
