Patent ID: 7074411

Claim:
A recombinant multimeric protein, comprising a) a polypeptide fusion monomer A, which consists of a C-terminal fragment of the Î± chain of C4BP containing one or two cysteine residues, wherein the C-terminal fragment is contained within the amino acid sequence represented by SEQ ID NO:7, and a polypeptide fragment which is heterologous in relation to said Î± chain, and b) a polypeptide fusion monomer B, which consists of a C-terminal fragment of the Î² chain of C4BP containing one or two cysteine residues, wherein the C-terminal fragment is contained within the amino acid sequence represented by SEQ ID NO:8, and a polypeptide fragment which is heterologous in relation to the Î² chain, monomer A and monomer B being linked to each other by a disulfide bridge between a cysteine of the Î± chain C terminal fragment and a cysteine of the Î² chain C-terminal fragment to form said multimeric protein.
