  • Porous hollow fiber membrane and methods of using it to select immune checkpoint inhibitor
    Patent number: 12474325
    Abstract: The present invention provides a porous hollow fiber membrane and methods of using the membrane to select an immune checkpoint inhibitor. The membrane can be used in animal models with an immune system and using a low-cost common mouse. The host immune system is unable to attack the cancer cells within the membrane and an animal study proves that the membrane system can be performed within animals.
