    Abstract: The present invention relates to the area of improved anti-IgE antibodies and antigen binding agents, and compositions thereof, which target IgE, for instance: for use in treating disorders caused by IgE (such as allergic responses, or certain autoimmune responses); and, in particular, disorders caused by the interaction of IgE with the FcεRI receptor. In particular, this invention relates to improved anti-IgE antibodies and antigen binding agents related to novel mutants of omalizumab (Xolair®). The improved anti-IgE antibodies and antigen binding agents of the invention may have improved affinity for IgE and/or an improved interaction with the Cε2 domain of IgE and/or an improved modified epitope on IgE (for instance further involving the Cε2 domain of IgE) and/or the ability to disassociate IgE from the FcεRI receptor for instance at pharmaceutically-relevant concentrations. In one aspect, improved or novel treatments for IgE mediated disorders are disclosed in which IgE is targeted (for instance free IgE and/or IgE complexed with the FcεRI receptor).

    Abstract: The present invention relates to a method of identifying, separating and characterizing a cell or a population of cells, by capturing at the cell surface, secreted soluble substances (such as an immunoglobulin) that cell or population of cell secrete. This is achieved by combing on a heterodimerically-tethered multispecific protein complex combining a binding specificity for the secreted molecule and a binding specificity for a surface antigen specific for that cell or population of cells. This method may be used in research and experimental purposes, such as patients' stratification in preparation of clinical trials or personalized therapies by identifying cell populations relevant to a pathology and/or prognosis.
