摘要:
The invention includes antibodies that provide superior anti-coagulant activity by binding native human TF with high affinity and specificity. Antibodies of the invention can effectively inhibit blood coagulation in vivo. Antibodies of the invention can bind native human TF, either alone or present in a TF: VIIa complex, effectively preventing factor X binding to TF or that complex, and thereby reducing blood coagulation. Preferred antibodies of the invention specifically bind a conformational epitope predominant to native human TF, which epitope provides an unexpectedly strong antibody binding site.
摘要:
The present invention features novel binding molecules and methods of improving the specific binding affinity of binding molecules, which methods do not use X-ray crystallography. For example, in one aspect, the invention features methods of making antibodies with improved specific binding affinity for a polypeptide produced during prothrombin activation. The present invention is useful for a variety of applications including, e.g., producing binding molecules with improved binding affinity; and screening for binding molecules which are in low abundance.

The invention includes antibodies that provide superior anti-coagulant activity by binding native human TF with high affinity and specificity. Antibodies of the invention can effectively inhibit blood coagulation in vivo. Antibodies of the invention can bind native human TF, either alone or present in a TF:FVIIa complex, effectively preventing factor X or FIX binding to TF or that complex, and thereby reducing blood coagulation. Preferred antibodies of the invention specifically bind a conformational epitope predominant to native human TF, which epitope provides an unexpectedly strong antibody binding site. Also provided are humanized antibodies and fragments thereof that bind to the TF.

摘要:
The present invention relates to novel complexes of major histocompatibility complexe (MHC) molecules and uses of such complexes. In one aspect, the invention relates to single chain MHC class II complexes that include a class II β2 chain modification, e.g., deletion of essentially the entire class II β2 chain. In another aspect, the invention features single chain MHC class II which comprise an immunoglobin constant chain or fragment. Further provided are polyspecific MHC complexes comprising at least one single chain MHC class II molecule. MHC complexes of the invention are useful for a variety of applications including: 1) in vitro screens for identification and isolation of peptides that modulate activity of selected T cells, including peptides that are T cell receptor antagonists and partial agonists, and 2) methods for suppressing or inducing an immune response in a mammal.

The present invention features fully soluble and functional single-chain T-cell receptor proteins. In one aspect, the invention features soluble fusion proteins comprising an immunoglobin light chain constant region or fragment thereof covalently linked to a single-chain T-cell receptor, wherein the single-chain T-cell receptor comprises a V-α chain covalently linked to a V-β chain by a peptide linker sequence. The single-chain T-cell receptor proteins have a variety of uses including use in screens to detect cells expressly desired MHC-peptide complexes.
摘要:
The present invention relates to novel complexes of major histocompability complex (MHC) molecules and uses of such complexes. In particular, the invention relates to MHC fusion complexes that contain an MHC molecule with a peptided-binding groove and a presenting peptide covalently linked to the MHC protein. Fusion complexes of the invention are useful for a variety of applications including in vitro screens for identification and isolation of peptides that modulate activity of selected T cells, including peptides that are T cell receptor antagonists and partial agonists, methods of suppressing an immune response of a mammal and methods for inducing an immune response in a mammal.
