    Product Information

    Product Description

    This Cell Signaling Technology® antibody is conjugated to Alexa Fluor® 647 fluorescent dye under optimal conditions. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated PD-L1 (D5V3B) Rabbit mAb #64988.

    Product Usage Information

    Application Dilution
    Immunohistochemistry (Paraffin) 1:50

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Protocol

    Specificity / Sensitivity

    PD-L1 (D5V3B) Rabbit mAb (Alexa Fluor® 647 Conjugate) recognizes endogenous levels of total mouse PD-L1 protein. Non-specific staining of keratinized epithelium has been observed.

    Species Reactivity:

    Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly216 of mouse PD-L1 protein.

    Background

    The programmed cell death 1 protein (PD-1, PDCD1, CD279) is a member of the CD28 family of immunoreceptors that regulate T cell activation and immune responses (1-3). The PD-1 protein contains an extracellular Ig V domain, a transmembrane domain, and a cytoplasmic tail that includes an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM). PD-1 is activated by the cell surface ligands PD-L1 and PD-L2 (4). Upon activation, PD-1 ITIM and ITSM phosphorylation leads to the recruitment of the protein tyrosine phosphatases SHP-1 and SHP-2, which suppress TCR signaling (5-7). In addition to activated T cells, PD-1 is expressed in activated B cells and monocytes, although its function in these cell types has not been fully characterized (8). The PD-1 pathway plays an important role in immune tolerance (3); however, research studies show that cancer cells often adopt this pathway to escape immune surveillance (9). Consequently, blockade of PD-1 and its ligands is proving to be a sound strategy for neoplastic intervention (10).
