    • The invention relates to methods of manipulating immobilised carbohydrates by derivatisation. Depending on the nature of the derivatisation, the carbohydrate may thereby be more easily detected and/or identified or handled. In particular, the invention relates to methods of preparing a reactive sugar comprising the steps of: i) providing a sample comprising a reducing sugar; ii) providing a solid support covalently attached to a linker comprising a capture group comprising an —NH2 group, wherein said linker optionally is attached to said solid support via a spacer; iii) reacting said reducing sugar with said —NH2 group, thereby obtaining an immobilised sugar; iv) reacting free —NH2 groups with a capping agent, wherein the capping agent comprises a reactive group capable of reacting with an —NH2 group; and v) reducing C═N bonds with a reducing agent, thereby obtaining an reactive sugar of the structure SugarCHn—NH— linked to a solid support via a linker and optionally a spacer, wherein n is 1 or 2.

    • The present invention provides an improved method of preparing a 4,7-di-O-alkyl chromogenic ketoside of N-acetylneuraminic acid (Neu5Ac) for use in detecting influenza virus types A and B. The ketosides are substrates that are selectively cleaved by a neuraminidase on influenza virus, but not be neuraminidases found on other viruses or on bacteria. The synthesis is efficient and provides large quantities of the ketoside for commercial development. The synthesis includes a step of alkylating the 4- and 7-hydroxyl groups of a protected alkyl ester alkyl ketoside derivative of Neu5Ac by a process that comprises contacting the derivative with a composition comprising an alkyl halide to form a 4,7-di-O-alkyl protected alkyl ester alkyl ketoside derivative of Neu5Ac. The synthesis alternatively includes protecting the 8- and 9-hydroxyl groups of an alkyl ester alkyl ketoside derivative of Neu5Ac by forming an 8,9-epoxide protected alkyl ester alkyl ketoside derivative of Neu5Ac.
