The immune system plays a key role in the recognition and destruction of cancerous cells. Utilizing and enhancing these properties lies at the heart of immunotherapy. Immune checkpoint therapies that target immuno-suppressive proteins such as PD-1, PD-L1 and CTLA4 have led to transformative new treatments for cancer. Purified versions of the proteins are critical for the development of antibodies, drug screening, and quality control assay development. In addition, novel proteins will help define the next generation of Immunotherapy targets.
