      RB613 Rat Anti-Human IL-2
      RB613 Rat Anti-Human IL-2

      Two color flow cytometric analysis of IL-2 expression by activated Human peripheral blood lymphocytes. Human peripheral blood mononuclear cells were stimulated for 5 h with Phorbol 12-Myristate 13-Acetate (PMA, Sigma P-8139; 50 ng/ml) and Calcium Ionophore A23187 (Sigma C-9275; 1 μ g/ml), in the presence of BD GolgiStop™ Protein Transport Inhibitor (containing Monensin) (Cat. No. 554724). The cells were harvested, washed with BD Pharmingen™ Stain Buffer (FBS) [Cat. No. 554656] and fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) followed by washing and permeabilization using BD Perm/Wash™ Buffer (Cat. No. 554723).

         The permeabilized cells were then stained in BD Perm/Wash™ Buffer with APC Mouse Anti-Human CD3 antibody (Cat. No. 561811) and with either BD Horizon™ RB613 Rat IgG2a, κ Isotype Control (Cat No. 571107; Left Plot) or with BD Horizon™ RB613 Mouse Anti-Human IL-2 antibody (Cat No. 571273/571333; Right Plot). The pseudocolor density plot showing the correlated expression of IL-2 (or Ig Isotype control staining) versus CD3 was derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Flow Cytometer System and FlowJo™ software.

      Preparation And Storage

      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 unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

      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

      1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      2. 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.
      3. 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).
      4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      5. An isotype control should be used at the same concentration as the antibody of interest.
      6. CF™ is a trademark of Biotium, Inc.
      7. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
      8. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background. For more information visit https://www.bdbiosciences.com/en-us/support/product-notices.
      9. For U.S. patents that may apply, see bd.com/patents.
      10. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
      11. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
      12. Tandem fluorochromes contain both an energy donor and an energy acceptor. Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from the donor may be observed. Additionally, multi-laser cytometers may directly excite both the donor and acceptor fluorochromes. Therefore, we recommend for every tandem conjugate, a matched individual single-stain control be acquired for generating a compensation or spectral unmixing matrix.
      13. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.

      MQ1-17H12

      The MQ1-17H12 monoclonal antibody specifically binds to the multifunctional cytokine, human Interleukin-2 (IL-2). IL-2 is produced by activated T cells and has multiple functions that can affect the growth, proliferation, differentiation and survival of many different target cell types including T cells, B cells, NK cells, monocytes and macrophages. The immunogen used to generate the MQ1-17H12 hybridoma was purified recombinant human IL-2 protein. The MQ1-17H12 antibody reportedly neutralizes the biological activity of human IL-2.

      RB613
      The BD Horizon RealBlue™ 613 (RB613) Dye is part of the BD® family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 492-nm and an emission maximum (Em Max) at 613-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB613 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with reduced excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB613 can be used as an alternative to PE-CF594 and we recommend using an optical filter centered near 610-nm (eg, a 610/20-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-CF594. RB613 is on average brighter than PE-CF594 off the blue laser.
