      RB780 Rat Anti-Human IL-4
      RB780 Rat Anti-Human IL-4
      Two-color flow cytometric analysis of IL-4 expression in stimulated Human peripheral blood lymphocytes.  Human peripheral blood mononuclear cells were either not stimulated (Left Plot) or were stimulated (Right Plot) for 6 hours with Phorbol 12-Myristate 13-Acetate (PMA; Sigma P-8139; 50 ng/ml final concentration) and Ionomycin (Sigma I-0634; 1 μg/ml final concentration) in the presence of  BD GolgiStop™  Protein Transport Inhibitor (containing Monensin) [Cat. No. 554724]. The cells were washed with BD Pharmingen™ Stain Buffer (FBS) [Cat. No. 554656], fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), and then washed, permeabilized with and stained in BD Perm/Wash™ Buffer (Cat. No. 554723) with APC Mouse Anti-Human CD3 antibody (Cat. No. 561811) and with BD Horizon™ RB780 Rat Anti-Human IL-4 antibody (Cat. No. 569087/569088; Right Plot).The bivariate pseudocolor density plots showing the correlated expression of IL-4 (or Ig Isotype control staining) versus CD3 were 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™ 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 unreacted dye was 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

      1. 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.
      2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      3. 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.
      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. 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).
      6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      7. An isotype control should be used at the same concentration as the antibody of interest.
      8. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
      9. Cy is a trademark of Global Life Sciences Solutions Germany GmbH or an affiliate doing business as Cytiva.
      10. 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.

      MP4-25D2

      The MP4-25D2 monoclonal antibody specifically binds to Interleukin-4 (IL-4). IL-4 is also known as Lymphocyte stimulatory factor 1, B cell stimulatory factor 1 (BSF-1), or B cell growth factor 1 (BCGF-1). IL-4 is produced by activated T cells, basophils, and mast cells. IL-4 is a multifunctional cytokine and growth factor that affects a variety of different target cell types. IL-4 can costimulate T cell proliferation and survival, as well as help drive Th2-like cell differentiation and effector functions. It costimulates B cell proliferation and survival, and can help B cells differentiate into IgG4- or IgE-producing cells. IL-4 can also diminish the proinflammatory functions of monocytes and macrophages. IL-4 exerts its biological effects by binding with high affinity to cell surface CD124 (IL-4Rα chain). CD124 forms signaling IL-4 receptor complexes with either CD132/common γ chain or CD213a1/IL-13Rα1 to form either Type I or Type II IL-4 Receptor complexes, respectively. The immunogen used to generate the MP4-25D2 hybridoma was purified recombinant human IL-4. This is a neutralizing antibody. The MP4-25D2 antibody has been reported to crossreact with IL-4 from rhesus monkeys. The use of the MP4-25D2 antibody for epitope mapping of human IL-4 has been described.

      RB780
      The BD Horizon RealBlue™ 780 (RB780) Dye is part of the BD family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 781-nm. Driven by BD innovation, RB780 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors.
