Scientific Data Images for Human PD‑1 Antibody

Detection of Human PD-1 antibody by Western Blot.

Detection of Human PD‑1 by Western Blot.

Western blot shows lysates of human tonsil tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human PD-1 Monoclonal Antibody (Catalog # MAB10864) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for PD-1 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
PD-1 antibody in Human Tonsil by Immunohistochemistry (IHC-P).

PD‑1 in Human Tonsil.

PD-1 was detected in immersion fixed paraffin-embedded sections of human tonsil using Mouse Anti-Human PD-1 Monoclonal Antibody (Catalog # MAB10864) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to lymphocytes.

PD-L1/B7-H1 Binding to PD-1 Blocked by Human PD-1 Antibody.

PD-L1/B7-H1 Binding to PD-1 Blocked by Human PD-1 Antibody.

In a functional ELISA, 0.09-0.72 µg/mL of this antibody (green line) will block 50% of the binding of 5 µg/mL of Recombinant Human PD-L1/B7-H1 Fc Chimera (orange line, Catalog # 156-B7) to immobilized Recombinant Human PD-1 His-tagged Protein (Catalog # 8986-PD) coated at 1 µg/mL (100 µL/well). At 5 µg/mL, this antibody will block >90% of the binding.

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).
