About CD8 ImmunoPET

The 89Zr CD8 Immuno-PET agent ([89Zr]-Df-IAB22M2C) is a [89Zr]-labeled minibody that binds the CD8 receptor on human T cells and is used for quantitative, non-invasive PET imaging of CD8 T cells in patients. CD8 T cells are the main effector cells involved in the immune response against tumor cells induced by immunotherapies and they also play a key role in multiple autoimmune diseases. As such, quantitative imaging of CD8 T cells can be used to diagnose the immune status of a patient, to measure the efficacy of immunotherapies and predict patient outcomes.
