Product Overview
This rabbit polyclonal antibody detects programmed cell death protein 1 (gene PDCD1) in human samples and is validated for IHC. The predicted molecular weight is 31.6 kDa.
PD-1 (PDCD1) is an inhibitory receptor on activated T cells, B cells and other immune cells. When bound by PD-L1 or PD-L2, it recruits the phosphatase SHP-2 to dampen T-cell receptor signaling, helping maintain self-tolerance; blocking PD-1 is the basis of widely used cancer immunotherapies.

Validated Applications
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
|---|
Samples with confirmed staining (IHC): human tonsil tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human PD1 fragment (Pro101–Leu288), expressed in E. coli. Sequence identity with the mouse ortholog: 59%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places programmed cell death protein 1 in the cell membrane.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
