Background: 

Programmed Cell Death-1 (PD-1), also called CD279, is a 288 amino acid cell surface protein that belongs to the immunoglobulin superfamily.  The protein is expressed on T cells, B cells and macrophages.  When PD-1 is joined with its ligand (CD274 or B7-H1), the immune cell’s activation and effector function are attenuated.  Research suggested that PD1 pathway is mainly involved with attenuation at periphery sites while the B7/CTLA-4 pathway is primarily involved with the attenuation of the activation of immune cells in secondary lymphoid organs.  PD-1 pathway is implicated with cancer’s immune-evasion, autoimmunity, and Listeria monocytogenes infection.

Application:

1. Indirect ELISA: The antibody is reactive to recombinant human programmed cell death-1 (PD-1).

2. IHC (see image):  This antibody reacts with thymus gland section. The thymus gland tissue section below was treated by heat induced epitope retrieval before primary antibody (20μg/mL) was added.  The secondary antibody was an HRP-labelled goat anti-mouse IgG antibody.
