Abstract: Disclosed herein are antibodies capable of binding to plasma kallikrein and inhibit its activity. Such antibodies interact with one or more critical residues in the catalytic domain of the plasma kallikrein. The antibodies may also contain specific heavy chain complementarity determining region 3 (CDRs) motifs and optionally specific residues at certain positions within both the heavy chain variable region and the light chain variable region.

Abstract: Proteins that bind to matrix metalloproteinase 14, combination therapies with such proteins and methods of using such proteins are described.

Abstract: Methods, kits and compositions for diagnosing and treating autoimmue diseases such as rheumatiodi arthritis, Crohn's disease, and ulcerative colitis.

Abstract: Methods are described for preventing or reducing ischemia and/or systemic inflammatory response in a patient such as perioperative blood loss and/or systemic inflammatory response in a patient subjected to cardiothoracic surgery, e.g. coronary artery bypass grafting and other surgical procedures, especially when such procedures involve extra-corporeal circulation, such as cardiopulmonary bypass.

Abstract: Disclosed herein are evacuated blood collection tubes comprising protease inhibitor cocktails in liquid form and uses thereof for assessing features associated with the contact system in a subject, including the endogenous level of contact system activation, the endogenous level of a drug that targets a component of contact system during treatment, and/or the immunogenicity of such a drug.

Abstract: Disclosed herein are anti-Factor Xlla antibodies and methods of using such for treating diseases associated with Factor XII, including diseases associated with contact system activation, plasma prekallikrein signaling (e.g., hereditary angioedema), and ocular diseases.

Abstract: Provided herein are plasma kallikrein antibodies binding to active plasma kallikrein and methods of using such antibodies in treating and preventing hereditary angioedema attack, such method may involve a first treatment period and optionally, a second treatment period. Also provided are methods of using such antibodies in treating hereditary angioedema involving a single dose of the antibody to a subject who has undergone a prior HAE treatment, followed by multiple doses of the same antibody if the subject experiences an HAE attack after the single dose.

Abstract: The present disclosure provides immunoassay methods of detecting a cleaved high molecular weight kininogen (HMWK) with high sensitivity and specificity and isolated antibodies that specifically bind cleaved HMWK

Abstract: The disclosure relates to antibodies that bind FcRn and methods of using these antibodies.

Abstract: Provided herein are plasma kallikrein antibodies binding to active plasma kallikrein and methods of using such antibodies in preventing hereditary angioedema attack or reducing the rate of hereditary angioedema attack.

Abstract: Methods, kits and compositions for diagnosing and treating autoimmune diseases such as rheumatiodi arthritis, Crohn's disease, and ulcerative colitis.

Abstract: Focused libraries of vectors or genetic packages that display, display and express, or comprise a member of a diverse family of antibody peptides, polypeptides or proteins and collectively display, display and express, or comprise at least a portion of the focused diversity of the family. The libraries have length and sequence diversities that mimic that found in native human antibodies.

Abstract: Provided are compositions and methods for preparing and identifying antibodies having CDR3s that vary in sequence and in length from very short to very long which in certain embodiments may bind to a carbohydrate moiety or the active site of an enzyme. Libraries coding for antibodies with the CDR3s are also provided. The libraries can be provided by modifying a pre-existing nucleic acid library.

Abstract: A eukaryotic expression vector capable of displaying a multi-chain polypeptide on the surface of a host cell is provided, such that the biological activity of the multi-chain polypeptide is exhibited at the surface of the host cell. Such a vector allows for the display of complex biologically active polypeptides, e.g., biologically active multi-chain polypeptides such as immunoglobulin Fab fragments. The present invention describes and enables the successful display of a multi-chain polypeptide on the surface of a eukaryotic host cell. Preferred vectors are described for expressing the chains of a multi-chain polypeptide in a host cell separately and independently (e.g., under separate vector control elements, and/or on separate expression vectors, thus forming a matched vector set).

Abstract: Described herein are bispecific antibodies that bind to plasma kallikrein (pKal) and Factor XII and methods of producing and using such bi-specific antibodies for treating diseases or disorders associated with the contact system, e.g., hereditary angioedema or thrombosis. One aspect of the present disclosure is a bispecific antibody, comprising: a first polypeptide that comprises a light chain of a first antibody, the light chain comprising a light chain variable region (VL) and a light chain constant region (CL) (e.g., a kappa light chain or a lambda light chain); and a second polypeptide that comprises a heavy chain of the first antibody, the heavy chain comprising a heavy chain variable region (VH) and a heavy chain constant region (CH).
