The present invention relates to novel, specific-binding therapeutic and/or diagnostic proteins directed against Hepcidin, which proteins preferably are muteins of a lipocalin protein. The invention also relates to nucleic acid molecules encoding such proteins and to methods for generation and use of such proteins and nucleic acid molecules. Accordingly, the invention also is directed to pharmaceutical and/or diagnostic compositions comprising such a lipocalin proteins, including uses of these proteins.

Provide is an anti-active GIP antibody which allows accurate detection of active GIP. The present invention provides an anti-active GIP antibody which binds to active GIP and does not substantially bind to nonactive GIP, the antibody recognizing at least one or more amino acids selected from the group consisting of amino acids at 8.sup.th to 10.sup.th position of the amino acid sequence represented by SEQ ID NO: 5, and comprising, in an H chain, a region comprising the following amino acid sequence (1) or a conservative sequence modification thereof: EMNPSDGRTHFNE (1).

The invention provides monoclonal antibody 6B8 and related antibodies. The 6B8 antibody binds to an epitope within residues 3-12 of IAPP. The antibodies of the invention are useful, for example, for treating disorders associated with IAPP accumulation, particularly accumulation of IAPP deposits. Such disorders include type 2 diabetes, metabolic syndrome, impaired insulin tolerance, impaired glucose tolerance, insulinomas, and related conditions.

A method for refolding an antibody, a process for producing a refolded antibody, a refolded antibody, and uses thereof are provided. A method for refolding an antibody in a liquid phase comprises the steps of denaturing an inactive antibody binding directly or through a linker to a peptide, the peptide having an isoelectric point lower than the isoelectric point of the inactive antibody, and dispersing in a liquid phase the peptide-binding inactive antibody denatured in the step above. Also provided is a process for producing a refolded antibody.
