Biotin Rat Anti-Human CXCR5 (CD185)
Detection of CXCR5 (CD185)  expression on human peripheral lymphocytes by Biotin Rat Anti-Human CXCR5 (CD185). Human peripheral blood mononuclear cells were stained with Biotin Rat Anti-Human CXCR5 (CD185)(Cat. No. 552118) and FITC Mouse Anti-Human CD3 (Cat. No. 555339; Left Panel) or FITC Mouse Anti-Human CD19 (Cat. No. 555412; Right Panel). The data reflects gating on lymphocytes, based on forward and side scattered light signals. The level of nonspecific staining was assessed by using Biotin Rat IgG2b, κ Isotype Control (Cat. No. 555847) and FITC-conjugated mouse IgG2a, κ Isotype Control (Cat. No. 555573) or FITC-conjugated mouse IgG1, κ Isotype Control (Cat. No. 555748). The quadrant markers for the bivariate dot plots were set based on the isotype controls.

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.

Recommended Assay Procedures

Biotin Rat Anti-Human CXCR5 (CD185) is effective for indirect immunofluorescence staining of human cells for flow cytometric analysis using 20 µl/10^6 cells. Combined with our Streptavidin-phycoerythrin (Cat. No. 554061), this antibody can be used for immunofluorescent staining and flow cytometric analyses of human leukocytes and cell lines expressing CXCR5 (see figure). For chemokine receptors expressed at low frequencies on the surface of cells, a 3-step staining procedure is recommended.

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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

RF8B2

The RF8B2 monoclonal antibody specifically binds to the human CXC chemokine receptor, CXCR5. CXCR5 (also known as CD185, BLR-1 NLR and MDR15), a seven transmembrane, G-protein-coupled receptor, is the specific receptor for CXC chemokine, CXCL13/BLC/BCA-1. In peripheral blood, CXCR5 expression is restricted to B lymphocytes and a small subset of CD4+ and CD8+ lymphocytes. The restricted expression pattern of CXCR5 on B cells and follicular T helper cells (Tfh) suggests that this receptor functions as a regulator of B and T cell migration. Stimulation of T cells with anti-CD3 monoclonal antibody leads to the down-regulation of CXCR5.

Biotin
Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
