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.

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 autonomously active B-cell receptors or B-cell receptor complexes. 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.

Abstract: The invention relates to the field of the preparation, identification and selection of biological binding molecules such as antibodies or fragments thereof, and also the use thereof in the context of therapy and prophylaxis of cancers, such as malignant B-cell neoplasia in particular. The binding molecules are capable of selectively binding to B-cell receptors that have a light chain according to SEQ ID NO. 18.

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.
