    Product Information

    Product Description

    This Cell Signaling Technology® antibody retains the antigen-binding Fab regions of the original parent host sequence from which it is engineered. This antibody is expected to exhibit the same species cross-reactivity as PD-L1 (E1L3N) Rabbit Monoclonal Antibody #13684.

    Product Usage Information

    Application Dilution
    Immunohistochemistry (Paraffin) 1:50

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    PD-L1 (E1L3N) Mouse Chimeric Monoclonal Antibody recognizes endogenous levels of total PD-L1 protein.

    Species Reactivity:

    Human

    Source / Purification

    This recombinant chimeric antibody is engineered from PD-L1 (E1L3N) Rabbit Monoclonal Antibody #13684 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody, but contains a mouse-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies.

    The parent antibody, PD-L1 (E1L3N) Rabbit Monoclonal Antibody #13684, is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human PD-L1 protein.

    Background

    Programmed cell death 1 ligand 1 (PD-L1, B7-H1, CD274) is a member of the B7 family of cell surface ligands that regulate T cell activation and immune responses. The PD-L1 ligand binds the PD-1 transmembrane receptor and inhibits T cell activation. PD-L1 was discovered following a search for novel B7 protein homologs and was later shown to be expressed by antigen presenting cells, activated T cells, and tissues including placenta, heart, and lung (1-3). Similar in structure to related B7 family members, PD-L1 protein contains extracellular IgV and IgC domains and a short, cytoplasmic region. Research studies demonstrate that PD-L1 is expressed in several tumor types, including melanoma, ovary, colon, lung, breast, and renal cell carcinomas (4-6). Expression of PD-L1 in cancer is associated with tumor-infiltrating lymphocytes, which mediate PD-L1 expression through the release of interferon gamma (7). Additional research links PD-L1 expression to cancers associated with viral infections (8,9).
