R718 Rat Anti-Human IL-4
Flow cytometric analysis for IL-4 in stimulated human peripheral blood mononuclear cells. Human PBMC were stimulated with immobilized Purified NA/LE Mouse Anti-Human CD3 (Cat. No. 555329; 10 µg/ml for plate coating) and soluble Purified NA/LE Mouse Anti-Human CD28 (Cat. No. 555725; 2 µg/ml) antibodies, recombinant human IL-2 (10 ng/ml final concentration; Cat. No. 554603) and human IL-4 (25 ng/ml final concentration; Cat. No. 554605) proteins for 2 days. The cells were subsequently cultured in medium containing recombinant human IL-2 and human IL-4 proteins for 3 days. Finally, the cells were harvested and stimulated for 5 hr with Phorbol 12-Myristate 13-Acetate (Sigma, Cat. No. P-8139; 50 ng/ml) and Ionomycin (Sigma, Cat. No. I-0634; 1 μg/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). The cells were then washed and stained in BD Perm/Wash™ Buffer (Cat. No. 554723) with BD Horizon™ R718 Rat IgG1 κ Isotype Control (Cat. No. 566948; Left Plot) or BD Horizon™ R718 Mouse Anti-Human IL-4 antibody (Cat. No. 566980; Right Plot) using BD Biosciences Intracellular Cytokine Staining protocol. A two-parameter pseudocolor density plot showing the correlated expression of IL-4 (or Ig Isotype control staining) versus autofluorescence measured in the FITC channel was derived from gated events with the forward and side light-scatter characteristics of lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Flow Cytometer 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 CompBead to ensure that BD CompBeads are appropriate for your specific cellular application.

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.

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.

The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.

R718
The BD Horizon™ Red 718 (R718) Dye is part of the BD red family of dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 695-nm and an emission maximum (Em Max) at 718-nm. Driven by BD innovation, R718 is designed to be excited by the red laser (627–640-nm) and detected using an optical filter centered near 720-nm (e.g., a 720/40-nm bandpass filter). R718 is a brighter alternative to Alexa Fluor™ 700. R718 is also a bright small molecule alternative to APC-R700 with lower spread into the APC detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
