Abstract:
1. A method for immobilising a bacterial polysaccharide (PS) to a solid surface, said polysaccharide having a keto-carboxy group (—C(═O)—COOH) or a ketal or hemiketal group corresponding thereto), the method comprising the steps of: a) forming a covalent bond between the carboxy group of the polysaccharide and a reporter molecule (RM), thereby forming a polysaccharide-reporter molecule conjugate (PS-RM), said reporter molecule comprising a recognition/substrate site; and b) immobilising the polysaccharide-reporter molecule conjugate (PS-RM) by forming a specific bond between the recognition/substrate site of said reporter molecule and a reception/reagent site of the solid surface.
