PE Rat Anti-Mouse IL-4
PE Rat Anti-Mouse IL-4
Expression of IL-4 by stimulated CD4+ and CD4-BALB/c spleen cells. BALB/c spleen cells were cultured for 72 h in medium containing Staphylococcus aureus enterotoxin B (2 µg/ml; Sigma, St. Louis, MO), recombinant mouse IL-2 (10 U/ml, Cat. No. 550069) and recombinant mouse IL-4 (2 ng/ml, Cat. No. 550067). The cells were harvested and restimulated for 5 h with anti-CD3 (145-2C11, Cat. No. 553057 at 2 µg/ml) and anti-CD28 (clone 37.51, Cat. No. 553294 at 2 µg/ml) antibodies in the presence of 3 µM monensin (BD GolgiStop, Cat No. 554704). The splenocytes were then stained with 0.25 µg of FITC-conjugated rat anti-mouse CD4 (FITC-RM4-5, Cat. No. 553047) and 0.25 µg of PE-conjugated rat anti-mouse IL-4 antibody (PE11B11, Cat. No 554435) by using the Pharmingen staining protocol (left panel). To demonstrate staining specificity, the binding of PE-11B11 was blocked by the preincubation of the conjugated antibody with excess recombinant mouse IL-4 (0.25 µg; Cat. No. 550067) (right panel) or by pre-blocking fixed/permeabilized cells with excess purified 11B11 mAb (5.0 µg; Cat. No. 554433) (data not shown), prior to staining. An approprate isotype control is PE-conjugated R3-34, (Cat. No. 554685). The quadrant markers for the bivariate dot plots were set based on the autofluorescence control, and verified using the cytokine-blocking or mAb blocking controls.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

Flow Cytometry: The 11B11 antibody has been reported to be useful for the immunofluorescent staining and flow cytometric analysis of IL-4-producing cells. The PE-conjugated 11B11 antibody can be used for multicolor flow cytometric analyses to identify and enumerate IL-4 producing cells within mixed cell populations (see right image). For optimal immunofluorescent staining with flow cytometric analysis, this anti-cytokine antibody should be pretitrated (≤ 0.5 µg mAb/million cells).   An approprate isotype control is PE-conjugated R3-34, (Cat. No. 554685). For specific methodology, please visit our web site, www.bdbiosciences.com, and go to the protocols section or the chapter on intracellular staining.

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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.

11B11

Interleukin-4 (IL-4) is a pleiotropic cytokine that has many roles, such as inducing the differentiation of naïve helper T cells (Th0 cells) to Th2 cells, stimulating activated B-cell and T-cell proliferation, and promoting immunoglobulin class switching to IgG1 and IgE in mouse B-cells.  IL-4 is expressed by CD4 T-cells, mast cells, basophils and eosinophils.  IL-4 was previously known as B-Cell Differentiation Factor (BCDF) or B-cell Stimulatory Factor (BSF1).  The 11B11 monoclonal antibody specifically binds to mouse IL-4. The immunogen used to generate the 11B11 hybridoma was partially purified mouse IL-4 prepared from the supernatant of Phorbol 12-Myristate 13-Acetate (PMA)-stimulated EL-4 cells. The 11B11 antibody is reportedly a neutralizing antibody.

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.
