BD Pharmingen™ Purified NA/LE Rat Anti-Mouse CD279 (PD-1)
Clone RMP1-14.rMAb (also known as RMP1-14)
(RUO)Flow cytometric analysis of PD-1 Ligand (PD-L2 Fc) binding blockade by Purified NA/LE Rat Anti-Mouse CD279 (PD-1) antibody on activated mouse leucocytes. Splenic leucocytes from C57BL/6 mice were cultured with plate-bound Purified NA/LE Hamster Anti-Mouse CD3e antibody (Cat. No. 553057) for 3 days. The activated leucocytes were harvested and stained with Recombinant Mouse PD-L2/B7-DC (Human IgG1) Fc Chimera Protein (R&D Systems, Cat. No. 1022-PL-100, blue line histogram) to assess PD-1 Ligand binding levels. Activated leucocytes preincubated with either Purified Rat IgG2a, κ Isotype Control (Cat. No. 553927; black line histogram) at 20 µg/test or Purified NA/LE Rat Anti-Mouse CD279 (PD-1) antibody (Cat. No. 566906; red line histogram) at 20 µg/test were also assessed prior to staining with the PD-L2 Fc protein. The cells were washed and stained with R-Phycoerythrin AffiniPure Goat Anti-Human IgG, Fcγ fragment specific (Jackson Immunoresearch, Cat. No. 109-115-098). The fluorescence histograms showing the bound levels of PD-L2 Fc protein were derived from gated events with the forward and side light-scatter characteristics of viable activated leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 and FlowJo® software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage
Recommended Assay Procedures
Clone RMP1-14.rMAb was developed for blocking application. For flow cytometric analysis of mouse CD279 (PD-1), we recommend clones J43 or RMP1-30. Note that clone RMP1-14.rMAb does not block clones J43 or RMP1-30.

Companion Products
RMP1-14.rMAb is a recombinant monoclonal antibody that specifically recognizes CD279 which is also known as Programmed Death-1 (PD-1). CD279 (PD-1) is a ~55-kDa type I transmembrane glycoprotein that is encoded by Pdcd1 (Programmed cell death 1) which belongs to the CD28/CTLA-4 family of immunoreceptors within the Ig superfamily. CD279 (PD-1) is comprised of an extracellular region with an IgV-like domain, a transmembrane sequence, and an intracellular region with an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM) that are associated with suppressive immunoregulatory functions. CD279 (PD-1) is variably expressed on some thymocyte subsets and developing B lymphocytes at the pro-B-cell stage. It is also inducibly expressed on activated myeloid cells, B cells, and T cells including exhausted T cells found in mice during chronic viral infections or cancer. Although this co-inhibitory receptor plays roles in mediating immunological tolerance and preventing autoimmune responses it can also inhibit protective immune responses against microbial infections and cancer. CD273 (also known as PD-L2 or B7-DC) and CD274 (PD-L1 or B7-H1) are members of the B7 family within the Ig superfamily. These molecules serve as ligands for CD279 (PD-1) and are variably expressed on lymphoid and nonlymphoid cells types including antigen-presenting cells and tumor cells. The RMP1-14 antibody reportedly blocks the binding of these natural ligands as well as recombinant mouse PD-L1-Ig and PD-L2-Ig proteins to CD279 (PD-1). Antibody-mediated inhibition of the interaction between PD-1 and its ligands can serve as an immune checkpoint blockade that can augment T-cell responses against tumor cells.
