  • Patent number: 11644459
    Abstract: The present invention relates to the field of producing, identifying, and selecting biological binding molecules, e.g. in particular antibodies or fragments thereof, which selectively bind to somatically hypermutated B-cell receptors or B-cell receptor complexes. The method is used in order to select a biological binding molecule which specifically binds to a B-cell receptor having hypermutated regions as the target receptor, but not to a B-cell receptor without hypermutated regions, and is carried out in a cell-based system using immature B cells which are in the pro/pre stage and cause a ‘Triple Knockout’ of the genes for RAG2 or RAG1, Lambda5, and SLP65.

  • Patent number: 11634487
    Abstract: The present invention relates to the field of production, identification and selection of biological binding molecules such as antibodies or fragments thereof, as well as to diagnostic procedures using them in the diagnosis of cancers, in particular malignant B-cell neoplasia. The binding molecules are able to selectively bind to autonomously active or autonomously activated B-cell receptors, the autonomously active or autonomously activated B-cell receptors being characterized by the presence of structural domains to which the binding molecule selectively binds and which are responsible for the autonomously active or autonomously activated state of the B-cell receptors.

  • Patent number: 11591391
    Abstract: The present invention relates to the field of the production, identification and selection of biological binding molecules such as antibodies or fragments thereof, as well as to their use in the therapy and prophylaxis of cancer diseases, such as, in particular, malignant B-cell neoplasia. The binding molecules are able to selectively bind to autonomously active or autonomously activated B-cell receptors, the autonomously active or autonomously activated B-cell receptors being characterized by the presence of structural domains to which the binding molecule selectively binds and which are responsible for the autonomously active or autonomously activated state of the B-cell receptors.

  • Publication number: 20230014648
    Abstract: The task of the invention is therefore making available transfer capsules that are taken up by the target cell type and permanently or transiently modify the target cell, without exerting any toxic effects on the cell during this process. The solution according to the invention consists of the use of monodisperse cores, so as to produce polyelectrolyte nanocapsules having cell-specific sizes from them. The sizes for hematopoietic cells are in a range of 20-80 nm, preferably in a range of 40-60 nm. In this regard, the sizes of the particles must be in a very narrow range, so as to prevent toxic effects from occurring. In order to keep the toxicity of the nanocapsules low, it is furthermore important to remove the nanoparticles around which the capsules are built up (cores) before use. Methods in this regard are known from the state of the art (for example dissolution by means of EDTA). A further task is the stabilization of the transfer capsules.

The method is used in order to select a biological binding molecule which specifically binds to an autonomously active or autonomously activated B-cell receptor as the target receptor, but not to an inactive or non-activated B-cell receptor, and is carried out in a cell-based system using immature B cells which are in the pro/pre-stage and cause a ‘triple knockout’ of the genes for RAG2 or RAG1, lambda5, and SLP65.

  • Publication number: 20220137077
    Abstract: In a flow cytometry measurement method, an analysis medium is provided, which includes a fluid and biological cells contained therein. A labeling molecule is provided and is brought in contact with the analysis medium in such a way that the labeling molecule can bind specifically to a target structure located on the surface of the cell if the cell has said cell structure. For the individual cells, flow cytometry measured values are captured for a first and a second physical parameter. The first parameter is fluorescence radiation emitted by the labeling molecule when the labeling molecule is excited. The cells are classified on the basis of the flow cytometry measured values. A first calibrator and a second calibrator are provided, which have solid particles matching in shape, size and material. A target structure matching the target structure of the cells is immobilized on the surface of the first calibrator. The second calibrator does not have said target structure.

  • Patent number: 10989631
    Abstract: A sampling device for taking samples from a gaseous beverage under pressure includes a connection for a beverage line, a pump having a pump chamber, a particle filter, a discharging opening for a beverage sample, an outlet for waste, a control device, and a line system connected to the pump chamber with adjustable valves. The sampling device is configured so a beverage sample with a volume smaller than the volume of the pump chamber is introduced from the connection into the pump chamber. The pump chamber is then separated from the connection and is expanded so gas exits from the beverage sample. The pump chamber is then connected to the outlet opening and compressed so gas which has passed out of the beverage sample is displaced. Then, the pump chamber is connected to the discharging opening via the particle filter and compressed so the beverage sample is displaced.
