Description

GlykoPrep HC cartridges are solid-phase extraction spin cartridges, packed with ~5 mg of Hypercarb™ porous graphitic carbon (PGC), designed for purification of glycans from non-carbohydrate material, including salts and proteins. When samples are loaded on the column, salts pass through, while glycans and protein adsorb onto the matrix. The glycans may then be selectively eluted from the column.

Applications:

• Desalting of N-glycans released by native digestion with e.g. PNGase F
• Protein removal and desalting following exoglycosidase digestion of released glycans (e.g. sialidase digestion, fucosidase digestion prior to 2-AB labeling)
• Cleanup of glycans released by hydrazinolysis
• Desalting glycan samples including anionic species prior to mass spectrometry
• Cleanup of fluorescently-labeled glycans (e.g. glycans labeled with 2-AB, InstantAB™) from labeling reactions*

Note: these cartridges are not suitable for removing detergent.

*Not recommended for cleanup of InstantPC-labeled N-glycans, as these must be stored in Gly-X/InstantPC Eluent with 10% ACN. Samples applied to HC cartridges must be aqueous or low organic (<5%).

Sample prep considerations:

• Glycan samples to be cleaned must be in an aqueous buffer or a buffer containing a low percentage (<5%) of organic solvent.• If the sample contains organic solvent, dilute with water until the organic solvent content is less than 5% by volume. For example, dilute a 5 μl 2-AB labeling reaction with 95 μl water prior to loading.• Samples should not contain detergents such as SDS.• Suggested starting upper limit for the HC cartridges is ~50 μg glycans. The binding capacity for specific glycoproteins & glycans may need to be determined. Minimum glycan load will depend on the sensitivity of the analytical methods used.

The H Cleanup Module requires minimal equipment. All you need is a centrifuge with a deep-well plate rotor (minimum 44 mm height) and a Starter Labware Kit (AM200).

Alternatively, the cartridges may be run in a microcentrifuge using Eppendorf tubes and AM400 adapters - please see the User Manual for details.
