Immuno-oncology is an exciting area within cancer research and among the most promising approaches to activating therapeutic antitumor immunity is through the blockade of immune checkpoints. The programmed cell death-1 (PD-1) immune checkpoint pathway is a negative regulator of T cell immune function. When PD-1 is bound to programmed cell death-ligand 1 (PD-L1), T cell response is suppressed. Many tumor cells escape anti-tumor immunity through their expression of Programmed Death Ligand 1 (PD-L1 or B7-H1), which interacts with T cell-expressed PD-1 and results in T cell apoptosis. PD-L1 expression has been studied in multiple different cancers. While several anti-PD-1 or PD-L1 monoclonal antibodies that block the PD-1/ PD-L1 complex formation have been developed to date, there remains a need for more robust, rapid, high-throughput assays to identify and qualify novel inhibitors of PD-1/PD-L1 binding and assays to detect expression levels of both binding partners. Find out how LANCE® Ultra Technology provides a fast, powerful, homogeneous platform for identifying and characterizing endogenous PD-L1 and PD-1 expression in human cells.
