  • Antibodies Binding to VISTA at Acidic pH
    Publication number: 20240092907
    Abstract: The present application relates to antibodies specifically binding to the V-domain immunoglobulin-containing suppressor of T-cell activation (VISTA) at acidic pH and their use in cancer treatment. In some embodiments, the antibodies bind specifically to human VISTA at acidic pH, but do not significantly bind to human VISTA at neutral or physiological pH.

  • System and method for performing intervention operations with a compliant guide
    Patent number: 8973665
    Abstract: A technique for subsea intervention operations incorporates use of a compliant guide that extends between a surface location and a subsea installation. The technique facilitates deployment of tool strings into a subsea well. For example, a portion of the compliant guide can be used as a subsea lubricator during pressure deployment of tool strings. In some applications, a tool entry guide can be connected into the subsea installation to facilitate deployment of tool strings into the subsea well.

  • System and technique for monitoring and managing the deployment of subsea equipment
    Patent number: 6725924
    Abstract: A system that is usable in a subsea well includes a tubular string that extends from a surface platform toward the sea floor. The string has an upper end and a lower remote end that is located closer to the sea floor than to the platform. At least one sensor of the system is located near the remote end of the string to monitor deployment of subsea equipment.
