The present teachings relate to methods, systems, and kits for the preparation, purification and/or analysis of a glycan or glycoconjugate, and specifically to a magnetic bead based sample preparation protocol. In some aspects, the sample preparation protocol can provide for glycoconjugate capture, glycan release, fluorescent derivatization, and glycan purification for subsequent capillary electrophoresis, liquid chromatography, or other glycoanalytical method using magnetic beads containing negatively charged carboxyl groups extending from the surface of the magnetic beads.

Glycan sample preparation

The present teachings relate to methods, systems, and kits for the preparation, purification and/or analysis of a glycan or glycoconjugate, and specifically to a magnetic bead based sample preparation protocol that can enable full automation and reduced sample preparation time relative to current methods of glycoanalysis. In some aspects, the sample preparation protocol can provide for glycoconjugate capture, glycan release, fluorescent derivatization, and glycan purification for subsequent capillary electrophoresis, liquid chromatography, or other glycoanalytical method without requiring time-consuming sample preparation steps such as centrifugation or vacuum-centrifugation.
