  • Patent number: 10829554
    Abstract: This disclosure provides ASCT2-binding molecules, e.g., anti-ASCT2 antibodies, and antigen-binding fragments thereof. In certain aspects, the ASCT2-binding molecules are conjugated to cytotoxic drugs, e.g., ASCT2 antibody-drug conjugates (ADCs). In certain aspects, the anti-ASCT2 antibodies and fragments thereof can be hybridoma-derived murine monoclonal antibodies, and humanized versions thereof. In certain aspects, the ASCT2-binding molecules bind specifically to cells expressing ASCT2, and in some instances, are internalized into the cells. In addition, this disclosure provides compositions and methods for diagnosing and treating diseases or disorders characterized by ASCT2 overexpression, e.g., certain types of cancer. In a particular embodiment, the disclosure provides methods for treating cancer using ASCT2 ADCs.

  • Patent number: 9578025
    Abstract: Verification of a user login to a secure account from a mobile device occurs when the user provides login credentials and a hardware identifier (ID) corresponding to the mobile device. The provided login credentials and hardware ID are then verified against a registry. Further, the mobile device determines and provides a geographic location of the mobile device using a global positioning system (GPS) component installed therein. The location provided by the mobile devices is then matched with a location of a network element with which the mobile device is currently communicating.
