Patent ID: 7504483

Claim:
A recombinant multimeric protein, comprising a) a polypeptide fusion monomer A, which consists of a C-terminal fragment of the α chain of C4BP consisting of SEQ ID NO: 11 and containing one or two cysteine residues, and a polypeptide fragment which is heterologous in relation to said α chain, b) a polypeptide fusion monomer B, which consists of a C-terminal fragment of the β chain of C4BP consisting of SEQ ID NO: 12 and containing one or two cysteine residues, and a polypeptide fragment which is heterologous in relation to the β chain, monomer A and monomer B being linked to each other by a disulfide bridge between a cysteine of the α chain C terminal fragment and a cysteine of the β chain C-terminal fragment to form said multimeric protein.
