Abstract: The present invention provides a method for immobilizing a polysaccharide (PS) to a solid surface, said polysaccharide having a keto-carboxy group (—C(?O)—COOH) or a ketal or hemiketal group corresponding thereto, e.g. derived from KDO (2-keto-3-deoxy-D-manno-octonic acid)), 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 (e.g. biotin or an anthraquinone); and (b) immobilizing the polysaccharide-report molecule conjugate by forming a specific bond (e.g. by photocoupling or formation of an affinity pair) between the recognition/substrate site of said reporter molecule and a reception/reagent site of the solid surface. The present invention also provides a solid surface thus obtainable and the use of such solid surfaces for diagnostic purposes, e.g.

Abstract: A hapten-polymer carrier complex was found to be useful for immunoassay purposes, specifically ELISAs, for the detection of pesticides and their degradation products in hydrosoil and ground water. The degradation products of Casoron G® (also known as dichlorobenzonitrile and dichlorbenil) and Prefix® (also known as chlorthiamid and dichlorobenzthiamide) are analytes detected with high specificity and sensitivity, particularly the degradation product BAM (2,6-dichlorobenzamide). The polymer carrier complex is bound to the hapten via a linker unit, strategically positioned meta to the amide or amide derivative of BAM.

Abstract: The invention relates to novel analysis slides or substrates with a closed configuration. The slides may be used for any application which normally utilizes a conventional microscope slide and can be used in conjunction with any type of equipment typically used to manipulate or evaluate a standard microscope slide. In particular, the invention provides closed slides for covalent immobilization of polypeptides and nucleic acids. Further provided are methods for carrying out biological assays using arrays of biomolecules immobilized on the slides of the invention. The arrays of the invention are comprised of a unique meandering or straight channel design as compared to the rectangular design of conventional arrays.

Abstract: A method for enhancing hybridisation of a capture oligonucleotide to a target sequence using a helper probe comprising modified nucleotide residues is disclosed. The method exhibits significantly improved binding abilities. In particular the method is suitable for detection of SNP sites.

Abstract: Chimeric oligonucleotides are provided that contain non-modified DNA or RNA residues and modified nucleic acid residues. A modified nucleic acid residue is placed in the −1 position of the 3′ and/or 5′ end of the oligonucleotide. The oligonucleotides can exhibit significantly enhanced hybridization properties and improved capabilities as primers in nucleic acid extension and amplification reactions.

Abstract: The present invention features methods for self-learning, self-engineering microarrays for the analysis of complex mixtures of nucleic acids and systems and apparatuses embodying such methods. In more particular aspects, the present invention features methods and systems that include inputting data relating to one or more biomolecules into a database; identifying at least one of a plurality of groupings for data to be obtained (mined) from the universal database; inputting at least one of the groupings into a neural network program, which can analyze the data and generate new design rules for predicting biological data; and adapting a software program including initial design rules to the new design rules.

Abstract: The present invention provides a method for immobilising a polysaccharide (PS) to a solid surface, said polysaccharide having a keto-carboxy group (—C(═O)—COOH) or a ketal or hemiketal group corresponding thereto, e.g. derived from KDO (2-keto-3-deoxy-D-manno-octonic acid)), 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 (e.g. biotin or an anthraquinone); and (b) immobilising the polysaccharide-report molecule conjugate by forming a specific bond (e.g. by photocoupling or formation of an affinity pair) between the recognition/substrate site of said reporter molecule and a reception/reagent site of the solid surface.

Abstract: The present invention relates to a method of detecting variant nucleic acid whose nucleotide sequence differs from one another at a single (or more) position(s). The method uses a set of chimeric oligonucleotides containing DNA monomers and monomers of a novel class of DNA analogues, locked nucleic acid (LNA). LNA oligomers obey the Watson-Crick base-pairing rules and form duplexes that are significantly more stable than similar duplexes formed by DNA. The “allele-specific” LNA-containing oligonucleotides wherein the LNA nucleotide(s) are found at the 3′ position can be extended by means of enzymes only where the nucleotide(s), which is/are terminal in direction of extension, is/are complementary to the corresponding nucleotides of the nucleic acid (of the one allele) to be detected. Thus discrimination between alleles without subsequent differential hybridization with labelled oligonucleotides is possible.
