  • Publication number: 20250043266
    Abstract: Compositions and methods for the preparation of high purity arginase and high efficiency preparation of monosubstituted polyethylene glycol conjugation of arginase are provided, as are methods for using arginase in combination with asparaginase to inhibit cancer cells. High purity arginase is provided by applying an initial high temperature precipitation step, followed by ion exchange to provide arginase at a purity of 90% or greater. Conjugation with either linear or branched polyethylene glycol is performed using a maleimide-derivatized polyethylene glycol at low molar excess relative to arginase and at reduced temperature. Such polyethylene glycol-derivatized arginase is useful in combination with asparaginase in inhibiting the growth of cancer cells, particularly cells that have low endogenous asparaginase expression.

  • Patent number: 12164033
    Abstract: Described are systems and methods for ToF imaging of a target. The ToF imaging system includes an optical splitter that splits the light beam from a light source into multiple transmitting light beams. The transmitting light beams are directed towards a target, and one or more portions return as reflected light beams. A detector generates detector signals, representative of the reflected light beams. An electronically-controlled mirror is used to change the angular position of the transmitting light beams incident on the target, so that different regions of the target can be measured at different time instants. The ToF imaging system uses a flash and scan process to flash one region(s) of the target with the transmitting light beams during one sub-frame exposure and to scan other region(s) of the target during subsequent sub-frame exposures. An image processing apparatus constructs target information from multiple sub-frame exposure.
