摘要:
According to the method for detecting optical properties, especially luminescence reactions and refraction behaviour of molecules (14) which are directly or indirectly bound on a support (12), electromagnetic waves, especially laser light (26), are radiated onto the support. The light that is emitted or refracted by the molecules is then detected by a detector (28). The detector and the support are moved in relation to each other during and after the radiation of the electromagnetic waves. The support used is especially a transparent support with integrated position markings (20) which can be detected by a detector, especially an optoelectronic scanning system. At least one of the integrated position markings is selected while the support and the detector are being moved in relation to each other or thereafter so that the light that is detected by the detector can be associated with a location on the support. A device for carrying out the method is provided with a detector, especially an optoelectronic scanning system, for detecting the position markings that are integrated in the support.
摘要:
According to the inventive method for applying substances to a support, especially monomers for the combinatorial synthesis of molecule libraries, the substances are first embedded in a matrix consisting of at least one solvent, said solvent being in a solid state of aggregation at a temperature below 90 °C, preferably below 50 °C. The substances that are embedded in the matrix form transport units which are subsequently applied to the support in a solid state of aggregation, at a temperature below 90 °C, preferably below 50 °C. Alternatively, the transport units can be dissolved with a second solvent part and applied to the support in a liquid state of aggregation, where they adopt a solid or gel-like stage of aggregation after said solvent part has completely or partially evaporated. The substances on the matrix are then mobilised by modifying their physical environment and brought into the vicinity of the support surface through a physical process. Here, the substances link up with the molecules. This method can be repeated to apply multiple layers to the support in precise positions. The method can be carried out using a device which essentially has the structure of a laser printer or a laser copier or an ink-jet printer.

The present invention relates to a method for selecting monoclonal antibodies. The method comprises the fusion of B-lymphocytes with myeloma cells to form hybridome cells that produce antibodies. The antibodies are presented on the cell surface of the hybridome cells by an antibody-binding protein. The invention also relates to the binding of antibodies to antigens and to means which can be used therefor.

摘要:
The invention relates to modularly constructed RNA molecules which can bind to a ligand and which are characterized by two sequence regions. Said first sequence region contributes to the maintenance of the three-dimensional structure of the RNA molecule, and a second sequence region is responsible for the specific bond of the ligand. These RNA molecules, e.g. the NINTROX-RNA, can be used for directly influencing the gene expression. The invention also relates to vectors containing the inventive RNA molecules, to medicaments and diagnostic compositions which contain said RNA molecules or vectors, to an antibody which specifically recognizes these RNA molecules or antisense RNA which specifically binds to these RNA molecules, or to ribozymes which split these RNA molecules. In addition, the invention relates to non-human mammals whose NINTROX gene is modified by inserting a heterologous sequence and to the cells obtained therefrom.
