General description

Maltoheptaose is a glucose heptamer.

Application

A partial hydrolysis of maltoheptaose has been used to prepare a dextran ladder in a study that assessed cationic labeling of oligosaccharides. The sensitivity of O-2-[aminoethyl]fluorescein was evaluated using maltoheptaose in a study that investigated the development of a novel fluorescent tag for the electrophoretic separation of oligosaccharides.

The effects of varying the electron energy and cationizing agents on electron activated dissociation (ExD) of metal-adducted oligosaccharides were explored, using permethylated maltoheptaose as the model system. Across the examined range of electron energy, the metal-adducted oligosaccharide exhibited several fragmentation
