    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.
