    摘要： A method for purification of a nucleic acid comprising the steps of (a) adsorbing on a substrate the nucleic acid from a composition containing (i) an aqueous buffer, (ii) salts in a high concentration, (iii) a water-miscible, non-acidic organic compound, and (iv) the nucleic acid; (b) optionally washing with a washing solution the substrate with the adsorbed nucleic acid; (c) contacting the substrate with the adsorbed nucleic acid with a solution containing salts in a lower concentration compared to the composition of step (a), thereby desorbing the nucleic acid from the substrate; (d) separating the solution with the desorbed nucleic acid from the substrate, thereby purifying the nucleic acid; and optionally (e) precipitating the desorbed nucleic acid from the solution of step (d) and isolating the precipitated nucleic acid, thereby further purifying the nucleic acid.

    摘要： The present invention concerns a method for the detection of an analyte in a sample liquid by luminescence measurement according to the principle of a ligand-receptor assay, e.g. an immunoassay or a hybridization assay or a combination thereof, wherein a sample liquid is incubated with at least one receptor which carries a luminescent label and the presence or/and the amount of the analyte to be detected is determined in the sample liquid by measuring the luminescence in a measuring medium containing dispersed components.

    摘要： Methods of optimising binding assays are disclosed using binding agents having binding sites specific for an analyte by varying the density of binding sites on a solid phase, advantageously extending the working range of the assay and/or improving the precision of the assay within a given range. Processes for manufacturing an assay kit following the optimisation method and to methods of carrying out assays for analytes using these assay kits are also provided.
