Detection of mouse PD‑1 by Western Blot. Western blot shows lysates of EL-4 mouse lymphoblast cell line. PVDF membrane was probed with 2 µg/mL of Rat Anti-Mouse PD-1 Monoclonal Antibody (Catalog # MAB77381) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). Specific bands were detected for PD-1 at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of PD-1 in HEK293 Human Cell Line Transfected with Mouse PD-1 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with either (A) mouse PD-1 or (B) irrelevant transfectants and eGFP was stained with Rat Anti-Mouse PD-1 Monoclonal Antibody (Catalog # MAB77381) followed by APC-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113). Quadrant markers were set based on isotype control antibody staining (Catalog # MAB006). View our protocol for Staining Membrane-associated Proteins.

Background: PD-1

Programmed Death-1 (PD-1) is a type I transmembrane protein belonging to the CD28/CTLA-4 family of immunoreceptors that mediate signals for regulating immune responses (1). Other members of this family include CD28, CTLA-4, and ICOS (2-4). PD-1 is most closely related to CTLA-4 and shares approximately 24% amino acid (aa) sequence identity. The mouse PD-1 gene encodes a 288 aa protein with a putative 20 aa signal peptide, a 149 aa extracellular region with one immunoglobulin-like V-type domain, a 21 aa transmembrane domain, and a 98 aa cytoplasmic region. 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 in mediating PD-1 signaling. Mouse and human PD-1 share approximately 69% aa sequence identity. Two B7 family proteins, PD-L1 (also called B7-H1) and PD-L2, have been identified as PD-1 ligands (5, 6). PD-1 is expressed on activated T cells, B cells, myeloid cells, and on a subset of thymocytes. PD-1 deficient mice have a defect in peripheral tolerance and spontaneously develop autoimmune diseases. Binding of PD-1 to PD-L1 or PD-L2 results in the inhibition of TCR-mediated proliferation and cytokine production as well as BCR-mediated signaling. PD-1 likely has an inhibitory role in regulating immune responses (1-4).
