Checkpoint Luciferase Reporter Cells

Immune checkpoint inhibitors: Interaction between PD-1 (blue) on a T-cell and PD-L1 (red) on a cancer cell blocked by therapeutic antibodies

Facilitate checkpoint inhibitor therapeutic development

Immune checkpoint inhibitors have shown recent success in the treatment of lung, liver, breast, renal, and skin cancers; however, the lack of immunological models with endogenous expression of checkpoint marker proteins is currently a conspicuous challenge in immuno-oncology.

To facilitate large-scale drug discovery of this growing class of immunomodulator, ATCC created tumor and immune cell lines with high endogenous expression of validated targets for immune checkpoint inhibitor therapeutics. In addition, we introduced a stably-expressed luciferase reporter system that can be used to readily detect, quantitate, and evaluate the efficacy, potency, and dynamics of the inhibitor and co-stimulatory expression levels.

These novel cell lines can be incorporated into simple blocking assays or be integrated into sophisticated co-culture cell-based drug screening assays. Read our application note or watch our poster presentation to see how these the cells can provide more physiologically relevant results.
