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.

Binding molecules for human factor VIII and factor VIII-like proteins

Provided herein are methods and compositions for purifying human factor VIII, human factor VIII-like peptide or fragments thereof. The methods comprise immobilizing a binding molecule for human factor VIII, human factor VIII-like protein or fragments thereof to a solid support, contacting the immobilized binding molecule with a solution containing the human factor VIII, human factor VIII-like protein or fragments thereof, and purifying the factor by separating the solution from the solid support.

Methods and compositions for purifying human factor VIII, factor VIII-like proteins or fragments thereof

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.
