Abstract: Binding molecules for detecting or isolating immunoglobulin Fc-region polypeptides are described, together with methods of use thereof. Preferred Fc-region binding polypeptides, recombinant bacteriophage expressing Fc-region binding polypeptides, and separation media exhibiting such polypeptides are particularly disclosed.

Abstract: Binding polypeptides comprising specific amino acid sequences are disclosed that bind B Lymphocyte Stimulator (BLyS) protein or BLyS-like polypeptides. The binding polypeptides can be used in methods of the invention for detecting or isolating BLyS protein or BLyS-like polypeptides in solutions or mixtures, such as blood, tissue samples, or conditioned media.

Abstract: It is an object of the present invention to provide novel binding molecules for factor VIII and factor VIII-like proteins. Preferred binding molecules of the present invention exhibit not only distinct characteristics for binding of the target factor VIII polypeptides but also specific and desirable characteristics for release (elution) of the target polypeptides. Especially preferred binding molecules according to the invention are short polypeptide sequences, characterized by a stable loop structure.

Abstract: Binding polypeptides that specifically bind BLyS protein or BLyS-like polypeptides can be used in methods of the invention for detecting, diagnosing, or prognosing a disease or disorder associated with aberrant BLyS or BLyS receptor expression or inappropriate function of BLyS or BLyS receptor, comprising BLyS binding polypeptides or fragments or variants thereof, that specifically bind to BLyS. The present invention further relates to methods and compositions for preventing, treating or ameliorating a disease or disorder associated with aberrant BLyS or BLyS receptor expression or inappropriate BLyS function or BLyS receptor function, comprising administering to an animal, preferably a human, an effective amount of one or more BLyS binding polypeptides or fragments or variants thereof, that specifically bind to BLyS.

Abstract: Methods for detecting human factor VIII or factor VIII-like polypeptides in and isolating it from solutions such as blood or conditioned media are disclosed, together with reagents suitable for the purpose comprising binding moieties that recognize human factor VIII and/or a factor VIII-like polypeptide and form a binding complex therewith. Preferred polypeptide binding moieties are particularly disclosed.
