Abstract: The invention relates to proteins containing any of the sequences according to general formula (Ih): X1CRX2X3X4X5??(Ih) where X1 is F, Y, L, P, Q, M, V, W, A, T and X2 is A, G, S, T and X3 is V, A, I, L, M, D, H, S and X4 is K, I, Q, R, H, S, F, M, N, L, V and X5 is R, V, I, K, M, Q, E, F, L, N, Y, D, S, H. and its salts, esters and pharmaceutically acceptable prodrugs. The invention further relates to pharmaceutical preparations and kits containing said proteins, to screening procedures using said proteins. The proteins of the invention are useful in the treatment or prevention of diseases that can be treated by inhibiting the complement system.

Abstract: The invention relates to peptides of the general formula (I) GX1CSX2SX3PPX4CX5PD (SEQ ID NO: 20), where X1 is Y, M, W, I, V, or A; X2 is R or K; X3 is Y, F, I, M, L, E, D, or H; X4 is V, I, or H; and X5 is I, V, Y, F, or W; and to the pharmaceutically acceptable salts, esters or prodrugs of the peptides according to general formula (I). In addition, the invention relates to pharmaceutical preparations, kits containing the preparations, and to procedures using the peptides and preparations.

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.
