Abstract: Methods, kits and compositions are described that include a non-naturally occurring kallikrein inhibitor and an anti-thrombolytic agent, e.g., an anti-fibrinolytic agent, for preventing or reducing blood loss and/or ischemia, e.g., ischemia associated with perioperative blood loss and cerebral ischemia, the onset of systemic inflammatory response, and/or reperfusion injury, e.g., reperfusion injury associated with cerebral ischemia or a focal brain ischemia, e.g., in patients subjected to invasive surgical procedures, especially procedures requiring cardiopulmonary bypass.

Abstract: Methods are described for preventing or reducing ischemia, e.g., cerebral ischemia, and/or reperfusion injury, e.g., reperfusion injury associated with cerebral ischemia, in a patient.

Abstract: The present invention provides polypeptides, peptide dimer, and multimeric complexes comprising at least one binding moiety for KDR or VEGF/KDR complex, which have a variety of uses wherever treating, detecting, isolating or localizing angiogenesis is advantageous. Particularly disclosed are synthetic, isolated polypeptides capable of binding KDR or VEGF/KDR complex with high affinity (e.g., having a KD<1 ?M), and dimer and multimeric constructs comprising these polypeptides.

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.

Abstract: The invention provides, inter alia, CD44-binding proteins, including CD4-binding antibodies, antibody fragments, and pharmaceutical compositions thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such proteins. Methods of using the proteins to detect CD44 or to modulate a CD44-expressing cell, e.g., in a subject, are also described.

Abstract: Disclosed is an artificial target-specific ligand that binds to both serum albumin and a particular molecular target. Interaction with serum albumin improves properties when administered to a subject. For example, an interaction between the ligand and serum albumin can extend the half-life of the ligand in circulation.

Abstract: Disclosed, inter alia, is a method of evaluating a sample that includes a serum protein and one or more one or more compounds physically associated with the serum protein. The method can include using a peptide ligand that specifically interacts with the serum protein to analyze a complex formed by the serum protein and its associated compounds.

Abstract: Antibodies and peptide ligands are described herein, which are specific for epitopes on MUC-H, which reside on the MUC1 extracellular fragment remaining on the cell surface after cleavage of the MUC1 protein.

Abstract: The invention provides, inter alia, a method of preparing a nucleic acid sequence that encodes a polypeptide that is displayed on a heterologous cell surface. The generally includes recombining a donor nucleic acid and an acceptor nucleic acid to form a recombined nucleic acid that encodes a polypeptide that is displayed. The recombination reaction is typically an in vivo reaction, in that at least the resolution of recombination intermediates occurs within a cell. Both site-specific recombination and homologous recombination can be used.

Abstract: Disclosed is a method that includes: (i) providing a plurality of initial nucleic acid cassettes that include: a) a first coding region encoding a first immunoglobulin variable domain, b) a second coding region encoding a second immunoglobulin variable domain, and c) a ribosomal binding site disposed between the first and second coding regions for translation of the second polypeptide in a first expression system, wherein the first and second coding regions are in the same translational orientation; (ii) modifying each nucleic acid cassette of the plurality in a single reaction mixture so that it is functional in a second expression system, wherein the first and second region remain physically attached during the modifying; (iii) introducing each modified nucleic acid cassette into a mammalian cell to produce a mixture of transfected cells; and (iv) expressing each modified nucleic acid cassette in the transfected cells.

Abstract: A device for transferring small drops of liquid from one or more liquid holders to one or more liquid destinations is disclosed. The device includes a support member and a plurality of fluid transfer members extending from the support member. Each fluid transfer member includes a flexible liquid transfer end.

Abstract: Disclosed are compositions and methods to generate functional target-binding proteins from at least two separate polypeptide chains, one including the target-binding domain, the other including an effector domain. For example, the two separate chains are reconstituted as a functional protein by a non-covalent binding interaction mediated by an interaction sequence or by intein-mediated ligation.
