Comparative and optimized dabsyl-amino acid analysis of synthetic phosphopeptides and glycopeptides.
L Gorbics et al.
Journal of chromatography. A, 676(1), 169-176 (1994-07-29)
The optimal conditions for amino acid analysis of phosphopeptides and N-acetylglucosamine- and N-acetylgalactosamine-containing glycopeptides were investigated by dabsyl-Cl derivatization and reversed-phase high-performance liquid chromatographic separation. By comparing the chromatographic behaviour of the dabsylated phosphoamino acids and dabsylated aminosugars on three
