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

Abstract: Provided herein are methods and kits for analyzing a biological sample obtained from a subject having, suspected of having, or being at risk for a disease associated with the contact activation system.

Abstract: Disclosed herein are anti-Factor XIIa 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: The disclosure relates to antibodies that bind FcRn and methods of using these antibodies.

Abstract: Provided herein are plasma kallikrein binding proteins such as antibodies binding to active plasma kallikrein and methods of using such proteins in treating hereditary angioedema.

Abstract: Methods useful in constructing libraries that collectively display and/or express members of diverse families of peptides, polypeptides or proteins and the libraries produced using those methods. Methods of screening those libraries and the peptides, polypeptides or proteins identified by such screens.

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: Disclosed herein are anti-Factor XIIa 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: Methods for differentiating full-length high molecular weight kininogen (HMWK) and cleaved HMWK in a sample are provided herein. Such methods may comprise treating a biological sample with a protease to generate a plurality of digested peptides, and measuring one or more signature peptides, which are indicative of cleaved HMWK and/or full-length HMWK.

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: 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: The invention provides assay methods of detecting last protease CI inhibitor (C1-INH) that binds plasma kallikreir, Factor XII, or both, and uses thereof for identifying subjects at risk for or suffering from a pKal-me-diated or bradykinin-mediated disorder. Provided methods permit analysis of patients with plasma kallikrein-mediated angioedema (KMA), or other diseases mediated by pKal useful in the evaluation and treatment.

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

Abstract: Methods useful in constructing libraries that collectively display and/or express members of diverse families of peptides, polypeptides or proteins and the libraries produced using those methods. Methods of screening those libraries and the peptides, polypeptides or proteins identified by such screens.

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: 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 herein are methods of treating and preventing hereditary angioedema attack in certain human patient subpopulations whose disease is well controlled in a first treatment period, which involves the use of an antibody that binds human plasma kallikrein. Such patients can be subject to a reduced dosage of the antibody and/or a prolonged dosing interval in a second treatment period.

Abstract: Provided herein are compounds that inhibit pKal, a serine protease whose activity is responsible for proteolytically cleaving kininogen and generating the potent vasodilator and pro-inflammatory peptide bradykinin, which can lead to painful and debilitating inflammatory attacks (e.g., edema). Also provided are pharmaceutical compositions and kits comprising the compounds, and methods of treating pKal-related diseases and disorders (e.g., edema) with the compounds in a subject, by administering the compounds and/or compositions described herein.

Abstract: Disclosed are methods for identifying desired members from a display libraries, including bacteriophage display libraries. Display library members can be amplified in the presence of a target compound so that cycles of selection can be rapidly completed.
