      PE Mouse Anti-Human IL-21 Receptor (CD360)
      PE Mouse Anti-Human IL-21 Receptor (CD360)
      Flow cytometric analysis of IL-21 receptor (CD360) in human peripheral lymphocytes. Whole blood was stained simultaneously with FITC Mouse Anti-Human CD19 (Cat. No. 555412) and PE Mouse Anti-Human IL-21 Receptor (CD360) (Cat. No. 560264; right panel) or PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; left panel). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Two-color dot plots depicting IL-21 receptor (CD360) (or Ig isotype control) versus CD19 expression were derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry was performed on a BD FACSCalibur™ System.

      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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

      Product Notices

      1. 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).
      2. An isotype control should be used at the same concentration as the antibody of interest.
      3. 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.
      4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      6. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

      17A12

      The 17A12 monoclonal antibody specifically binds to the IL-21 Receptor (IL-21R). The IL-21R, also known as CD360, is a 538 amino acid cytokine receptor with an extracellular domain consisting of one copy of the conserved WSXWS -containing cytokine-binding domain. The IL-21 receptor combines with the common cytokine-receptor γ-chain to form a functional receptor complex for IL-21. IL-21 is mainly produced by activated CD4+ T cells including T follicular helper (Tfh) cells. IL-21R is preferentially expressed by B cells, T cells, NK cells, some populations of myeloid cells, keratinocytes, and dendritic cells. Binding of its ligand, IL-21, in these cells results in the activation of the Jak/Stat signal transduction pathway.  The effects IL-21 ligand binding has pleiotropic actions such as augmenting the proliferation of T cells, driving of B cells into memory cells, terminally differentiating plasma cells and augmenting the activity of natural killer cells. IL-21 receptor has anti-tumor activity and might have a role in the development of autoimmunity; it has been reported that the IL-21 receptor affects the homeostasis of regulatory T cells and it could enhance T cell-activated responses in human immune-inflammatory diseases.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE 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 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
