Eurofins Discovery | iONCscanĀ Services for Co-Stimulatory and Inhibitory Checkpoint Receptors

Accelerate Cancer Immunotherapy Drug Development by Outsourcing Your Screening and Potency Needs

Regulation of immune responses is tightly controlled through a balance of co-stimulatory and inhibitory checkpoint receptors, often exploited by many cancers. Therefore, therapeutics that block inhibitory receptors or activate immune-stimulatory checkpoint receptors are powerful agents to restore anti-tumor immune responses, such as anti-PD-1 therapy.  However, developing drugs targeting these checkpoint proteins is quite challenging as cell-based assays used to screen for functional drugs are often difficult to create, involve the use of primary cells, and have long, complicated protocols.  To solve this bottleneck, Eurofins DiscoverX’s iONCscan Services offer an expanding menu of cell-based assays that can enable screening & potency determination for immunotherapy drugs.
