    Cell-based Assays for Immuno-Oncology I in vitro CRO Services I Cancer ImmunoTherapy screening

    Explicyte immuno-oncology is a preclinical CRO providing research services for the in vitro screening of novel cancer immunotherapies, including small molecules, monoclonal antibodies, BiTEs, ADCs, CAR-T cell therapies, and Natural Killer (NK) cell therapies. Our in vitro cancer models, co-cultured with immune cells, can be treated with immune checkpoint inhibitors, such as anti-PD-1/PDL-1 and CTLA-4 antibodies, for combinatorial strategies. Besides functional cellular assays to test the efficacy of anti-cancer immunotherapies, Explicyte offers a range of dedicated immuno-oncology assays for mechanism of action studies (MoA), such as cytokine release assays, immuno-phenotyping by FACS, and transcriptomic studies (RT-qPCR). Cancer immunotherapy strategies can be divided in three main categories including cytokines and immunomodulatory agents, antibody-based, and cell-based therapies. Explicyte’s expertise and advanced technologies have been harnessed so as to develop and build a cell-based service portfolio for immuno-oncology drug discovery. Our in vitro models & assays are sensitive, quantitative, and high throughput-compatible, thereby allowing to characterize and understand test compound’s effects, and identify single immunotherapeutic candidates or combination strategies that elicit immune cell functions and/or tumor cell sensitivity.
