Expression of IL-4 by stimulated CD4+ and CD4-Balb/c spleen cells. BALB/c spleen cells were cultured for 72 hours in medium containing Staphylococcus aureus enterotoxin B (2 µg/ml final concentration; Sigma, St. Louis, MO), recombinant mouse IL-2 (10 U/ml final concentration; Cat. No. 550069) and recombinant mouse IL-4 (2 ng/ml final concentration; Cat. No. 550067). The cells were harvested and restimulated for 5 hours with anti-CD3 (2 µg/ml final concentration; 145-2C11, Cat. No. 553057) and anti-CD28 (2 µg/ml final concentration; clone 37.51, Cat. No. 553294) antibodies in the presence of GolgiStop™ (3 µM final concentration; Cat. No. 554724). 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 APC-conjugated rat anti-mouse IL-4 antibody (APC-11B11, Cat. No. 554436) by using Pharmingen's staining protocol (left panel). To demonstrate staining specificity, the binding of APC-11B11 was blocked by the preincubation of the conjugated antibody with excess recombinant mouse IL-4 (0.25 µg; Cat. No. 550037) (middle panel) or by pre-blocking fixed/permeabilized cells with excess purified \"cold\" 11B11 mouse antibody (5.0 µg; Cat. No. 554433) (right panel) prior to staining. The quadrant markers for the bivariate dot plots were set based on the autofluorescence control, and verified using the cytokine-blocking and \"cold\" mouse antibody blocking controls. This APC-conjugated reagent can be used in any flow cytometer equipped with a a dye, HeNE or red diode laser. These include the dual laser FACStarPLUS™, FACS Vantage™ or FACSCalibur™.

Preparation And Storage
Recommended Assay Procedures
Immunofluorescent Staining and Flow Cytometric Analysis: The APC- conjugated 11B11 antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IL-4 producing cells within mixed cell populations. The use of an isotype control, such as rat IgG1 isotype control, APC-R3-34 (Cat. 554686) is recommended. For specific methodology, please visit our web site, www.bdbiosciences.com, and go to the Technical Resources/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
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- 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.
- This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.

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.
