Detection of Human PD‑1 by Western Blot. Western blot shows lysates of NS0 mouse myeloma cell line mock transfected or transfected with human PD-1. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human PD‑1 Monoclonal Antibody (Catalog # MAB10866) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for PD‑1 at approximately 75 kDa (as indicated). GAPDH (2275-PC-100) is shown as a loading control.This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of PD-1 in HEK293 Human Cell Line transfected with Human PD-1 and eGFP by Flow Cytometry HEK293 human embryonic kidney cell line transfected with either (A) human PD-1 or (B) irrelevant protein, and eGFP, was stained with Mouse anti-human PD-1 monoclonal antibody (Catalog # MAB10866) followed by Allophycocyanin-conjugated anti-Mouse IgG Secondary Antibody (F0101B). Quadrant markers were set based on control antibody staining (MAB002, data not shown). Staining was performed using our Staining Membrane-Associated Proteins protocol.

Background: PD-1
Programmed Death-1 receptor (PD-1), also known as CD279, is type I transmembrane protein belonging to the CD28 family of immune regulatory receptors (1). Other members of this family include CD28, CTLA-4, ICOS, and BTLA (2-5). Mature human PD-1 consists of a 148 amino acid (aa) extracellular region (ECD) with one immunoglobulin-like V-type domain, a 24 aa transmembrane domain, and a 95 aa cytoplasmic region. The human PD-1 ECD shares 65% aa sequence identity with the mouse PD-1 ECD. The cytoplasmic tail contains two tyrosine residues that form the immunoreceptor tyrosine-based inhibitory motif (ITIM) and immunoreceptor tyrosine-based switch motif (ITSM) that are important for mediating PD-1 signaling. PD-1 acts as a monomeric receptor and interacts in a 1:1 stoichiometric ratio with its ligands PD-L1 (B7-H1) and PD-L2 (B7-DC) (6, 7). PD‑1 is expressed on activated T cells, B cells, monocytes, and dendritic cells while PD-L1 expression is constitutive on the same cells and also on nonhematopoietic cells such as lung endothelial cells and hepatocytes (8, 9). Ligation of PD-L1 with PD-1 induces co-inhibitory signals on T cells promoting their apoptosis, anergy, and functional exhaustion (10). Thus, the PD-1: PD-L1 interaction is a key regulator of the threshold of immune response and peripheral immune tolerance (11). Finally, blockade of the PD-1: PD-L1 interaction by either antibodies or genetic manipulation accelerates tumor eradication and shows potential for improving cancer immunotherapy (12, 13, 14).
