  • Publication number: 20240002533
    Abstract: Arginase 1 binders comprising human antibodies and antigen-binding fragments thereof that inhibit the activity of human Arginase 1 (hArg1) are described. These Arginase 1 binders present an alternative mechanism for inhibiting hArg1 activity and highlight the ability to utilize binders as probes in the discovery and development of peptide and small molecule inhibitors for enzymes in general.

  • Patent number: 11104721
    Abstract: The present invention provides, in part, an antibody display system that simultaneously uses a secretion and a display mode. A bait complexed with a monovalent antibody fragment can be expressed on the surface of the host cell wherein the fragment may be assayed for antigen binding while full antibody is simultaneously secreted from the host cell. Methods of using the system for identifying antibodies that bind specifically to an antigen of interest are also provided. Polypeptides, polynucleotides and host cells useful for making the antibody display system are also provided along with methods of use thereof.

  • Patent number: 10577600
    Abstract: The present invention provides, in part, an antibody display system that simultaneously uses a secretion and a display mode. Embodiments of the invention provide a system in which a bait complexed with a monovalent antibody fragment can be captured prior to secretion in a host cell by virtue of surface displaying an antibody light chain and utilizing the covalent interaction of this light chain with the heavy chain of an antibody molecule that is co-expressed in the same host. Polypeptides, polynucleotides and host cells useful for making the antibody display system are also provided along with methods of using the system for identifying antibodies that bind specifically to an antigen of interest.
