Research interests

Molecular, immunological and structural characterization of allergen-specific antibodies and nanobodies to answer fundamental questions regarding the interaction allergen/IgE antibodies as well as to develop tools for diagnosis, prevention and treatment of allergy. 

Techniques, methods & infrastructure

Our expertise includes a broad spectrum of state-of-the-art-methodologies in molecular and cellular biology and immunology, e.g. generation of antibody/nanobody libraries, phage display technology, isolation and characterization of monoclonal antibodies/nanobodies, cell culture, mediator release experiments, DNA cloning, ELISA, immunoblotting, Biacore, mouse models.
