Checkpoint inhibitor therapeutic antibody blocking PD-1 protein on T cell and preventing it to bind to PD-1L on cancer cell

Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting

San Diego Convention Center, San Diego, California

November 01, 2023 - November 05, 2023

The SITC Annual Meeting brought together a global community of scientists focused on cancer immunotherapy and tumor immunology. Check out our poster presentations from the event and explore our immune checkpoint reporter cells, CAR-T luciferase reporter cells, THP-1 reporter cells, 2-D and 3-D patient-derived cancer models, human primary cells, and cancer panels to see how we can support your work!
