2′-/3′-AHC-GDP

2′-/3′-AHC-GDP is an analogue of guanosine-5′-O-diphosphate (GDP) in which a hexyl spacer with a terminal amino group has been attached either to the ribose 2′-hydroxy group or to the 3′-hydroxy group by a carbamate bond. It is suitable as a ligand in affinity chromatography or for coupling of various labelling structures including fluorophores. The spacer is connected to the ribose 2′-hydroxy group of the guanosine part.
