Abstract: The invention relates to unglycosylated folded C-terminal fragments of a multidomain serine protease of the complement cascade obtainable by expression in a bacterial host, wherein said serine protease is capable of binding a recognition molecule of the complement cascade, e.g. C1 or MBL. The invention also relates to methods and bacterial expression vectors for the preparation of said fragments, uses of said fragments for raising antibodies and screening substrates or inhibitors of said serine proteases and uses of the fragments in research and treatment of complement related disorders. The invention also relates to assay methods for assessing MASP-1 and MASP-2 levels in a sample of biological origin. The invention provides for research tools, assays and diagnostic kits useful in complement research and research and diagnosis of complement related disorders.

Abstract: In general, the invention relates to receptors capable of the efficient recognition and binding of target molecules, said receptors being composed of flagellin proteins which comprise the flagellar filaments of bacteria. More closely, the invention relates to modified flagellins or flagellin fragments useful as receptors, and filamentous receptor-structures comprising them. Moreover, the invention relates to procedures for their preparation and their uses. Flagellin-based receptors can be produced easily and inexpensively by bacteria, and purified with an ease without lysing the cells. Moreover, flagellins, due to their polymerization ability, can be used to build various filamentous structures. Starting from flagellin receptors of the invention filaments of desired length and construction can be prepared with a very high binding site density on their surface. These supramolecular objects may serve as basic recognition units for biological sensors and diagnostic kits.
