Scientific Data Images for Mouse PD-1 Antibody

Detection of Mouse PD-1 antibody by Western Blot.

Detection of Mouse PD‑1 by Western Blot.

Western blot shows lysates of EL-4 mouse lymphoblast cell line and CTLL-2 mouse cytotoxic T cell line (negative control). PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Mouse PD-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1021) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was 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 Mouse PD-1 antibody by Western Blot.

Detection of Mouse PD‑1 by Western Blot.

Western blot shows lysates of 293T human embryonic kidney cell line mock transfected or transfected with mouse PD-1. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Mouse PD-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1021) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for PD-1 at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
PD-1 antibody in Mouse Thymus by Immunohistochemistry (IHC-Fr).

PD-1 in Mouse Thymus.

PD-1 was detected in perfusion fixed frozen sections of mouse thymus using 15 µg/mL Mouse PD-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1021) overnight at 4 °C. Tissue was stained (red) and counterstained (green). View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Background: PD-1

Programmed Death-1 (PD-1) is 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).
