Methylamidation
Web1 mrt. 2024 · Methylamidation can label all carboxyl groups regardless of their position. To check the methylamidation reaction efficiency, we used a synthetic peptide with the sequence of TPVEPEVAIHR ([M+H] + m/z 1247.7) as a model. After methylamidation reaction, the original peptide peak disappeared while another peak emerged at m/z … WebAfter methylamidation, sialylated glycans can be analyzed by MALDI-MS without loss of the sialic acid moiety.

WebThe methylamidation step leads to a 24% increase in the peak capacity of the separation and direct correlation of electrophoretic and MALDI-MS results. In total, 37 unique N- glycan structures were assigned to 52 different peaks recorded in the electropherograms of the serum samples. WebThe repeatability of methylamidation was examined to evaluate the applicability of the approach to profiling of O-acetylation in sialic acids. In conclusion, the combination of methylamidation and permethylation methodology is a powerful MALDI-TOF MS-based tool for profiling O-acetylation in sialic acids applicable to screening of N-glycans.
