Brand: BD Horizon™
SKU: 568985

Clone IPI652.rMAb (also known as IPI652.rMAb)

(RUO)

Flow cytometric analysis of PD-L1 (CD274) expression on activated Human lymphocytes. Human peripheral blood mononuclear cells (PBMC) were stimulated with Phytohemagglutinin (PHA) for 3 days and stained with either BD Horizon™ PE-CF594 Mouse IgG1, κ Isotype Control (Cat. No. 562292; dashed line histogram) or BD Horizon™ PE-CF594 Mouse Anti-Human PD-L1 (CD274) antibody (Cat. No. 568984/568985; solid line histogram). DAPI (4',6-Diamidino-2-Phenylindole, Dihydrochloride) Solution (Cat. No. 564907) was added to cells right before analysis. The fluorescence histogram showing PD-L1 (CD274) expression [or Ig Isotype control staining] was derived from gated events with the forward and side light-scatter characteristics of activated viable (DAPI-negative) lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
An isotype control should be used at the same concentration as the antibody of interest.

Antibody Details

IPI652.rMAb

The IPI652.rMAb recombinant monoclonal antibody specifically recognizes Programmed cell death 1 ligand 1 (PDCD1 ligand 1, PDCD1L1, PDCD1LG1) which is also known as Programmed death ligand 1 (PD-L1 or PDL1) as well as CD274, or B7 homolog 1 (B7-H1, B7H1). PD-L1 (CD274) and PD-L2 (CD273) are type I transmembrane glycoproteins that belong to the B7 family within the Ig gene superfamily and serve as ligands for CD279 (Program Death 1/PD-1). PD-L1 (CD274) is expressed on antigen-presenting cells including activated monocytes, macrophages, and dendritic cells (DCs) as well as activated T cells, B cells, NK cells, and keratinocytes. PD-L1 (CD274) is also variably expressed on placental trophoblasts, myocardial endothelium, cortical thymic epithelial cells, and tumor cells. PD-L1-mediated signaling through PD-1 regulates T cell responses important for providing protective immunity while maintaining peripheral tolerance. This immune signaling checkpoint may also suppress antitumor immune responses and prevent tumor rejection.

Format Details

PE-CF594

BD Horizon™ PE-CF594 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496-nm and 566-nm and an acceptor dye with an emission maximum (Em Max) at 615-nm. PE-CF594, driven by BD innovation, is designed to be excited by the blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and detected using an optical filter centered near 615 nm (e.g., a 610/20-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and the acceptor dye can be excited by the green (532-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: PE-CF594

Excitation Source: Yellow-Green 488 nm, 532 nm, 561 nm

Excitation Max: 496 nm, 566 nm
