PD-1

Background

Tumor cells can be recognized by the immune system and even eliminated. PD-1 is expressed in activated T cells and tumor infiltrating lymphocytes involved in tumor cell immunity, while tumor cells express PD-L1 and PD-L2 ligands of PD-1 in their microenvironment to complete immune escape. This antibody is widely used in the detection of PD-1 in various tumor tissues and their microenvironment, which can help the application of targeted drugs.
