Abstract: Disclosed herein are methods, systems, mediums, and kits for use in phenotyping antibody responses via devices such as surface plasmon resonance devices. Such phenotypes can include total target-specific antibody titers, quantitative isotype distribution of the target-specific antibodies, and/or epitope specificity of the target-specific antibodies. Other methods, systems, mediums, and kits are also disclosed.

Abstract: Provided herein are methods and compositions for preventing or reducing an initial immune response to factor VIII in patients suffering from hemophilia A and for reducing the intensity of the immune response in patients having pre-formed inhibitor antibodies against factor VIII.

Abstract: A detailed three-dimensional structure for the C-terminal C2 domain of blood coagulation factor VIII is disclosed. The novel truncated factor VIII constructs which were designed so as to omit a significant portion of the flexible full length protein are also part of the present invention. In addition, the crystals of the protein, both in the presence and absence of bound ligands are also included. Furthermore, methods of identifying antagonists of the human factor VIII protein which can be used to inhibit coagulation or to stabilize and activate factor VIII mutants are also disclosed. Furthermore, methods of identifying variations of the C2 domain sequence and structure that can be incorporated into intact factor VIII for the purpose Of administration to hemophiliac patients who are immunoreactive against wild type factor VIII are disclosed.
