PE-CF594 Rat Anti-Mouse IL-4
PE-CF594 Rat Anti-Mouse IL-4

Flow cytometric analysis of IL-4 expressed in activated mouse splenocytes. Splenocytes from C57BL/6 mice were enriched for CD4+ T cells by positive selection using Purified NA/LE Rat Anti-Mouse CD4 antibody-coated plates (GK1.5, Cat. No.553726;10 μg/ml) for 1 hr at 4°C. The CD4+ T cells were harvested and stimulated with plate-bound Purified NA/LE Hamster Anti-Mouse CD3e (145-2C11, Cat. No. 553057;10 μg/ml) and soluble Purified NA/LE Hamster Anti-Mouse CD28 (37.51, Cat. No. 553294; 2 μg/ml) antibody and Recombinant Mouse IL-2 (Cat. No. 550069; 10 ng/ml) and IL-4 (Cat. No. 550067; 50 ng/ml) for 2 days. The cells were expanded in IL-2 and IL-4 for 3 days and then washed and stimulated for 4 hrs with PMA (Sigma, Cat. No. P-8139; 5 ng/ml) and ionomycin (Sigma, Cat. No. P-8139; 500 ng) in the presence of BD GolgiPlug™ Protein Transport Inhibitor (Containing Brefeldin A) (Cat. No. 555029).

     The activated cells were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), permeabilized using the BD Perm/Wash™ Permeabilization Buffer (Cat. No. 554723) and then stained either with a BD Horizon™ PE-CF594 Rat IgG1, κ Isotype Control (Cat. No. 562309, Left Panel) or with the BD Horizon™ PE-CF594 Rat Anti-Mouse IL-4 antibody (Cat. No. 562450, Right Panel). Two-color dot plots showing IL-4 (or Ig isotype control staining) versus autofluorescence were derived from gated events with the forward and light scattering characteristics of intact lymphocytes. Flow cytometry was performed using a BD LSR™ II Flow Cytometry System.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The antibody was conjugated with BD Horizon™ PE-CF594 under optimum conditions, and unconjugated antibody and free PE-CF594 were removed. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Recommended Assay Procedures

Immunofluorescent Staining and Flow Cytometric Analysis: The APC- conjugated 11B11 antibody (Cat. No. 562045/554436) can be used 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 in the Immune Function Handbook.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  5. 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.
  6. 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.
  7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

  10. When excited by the yellow-green (561-nm) laser, the fluorescence may be brighter than when excited by the blue (488-nm) laser.

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.

This antibody is conjugated to BD Horizon™ PE-CF594, which has been developed exclusively by BD Biosciences as a better alternative to PE-Texas Red®. PE-CF594 excites and emits at similar wavelengths to PE-Texas Red® yet exhibits improved brightness and spectral characteristics. Due to PE having maximal absorption peaks at 496 nm and 564 nm, PE-CF594 can be excited by the blue (488-nm), green (532-nm) and yellow-green (561-nm) lasers and can be detected with the same filter set as PE-Texas Red® (eg 610/20-nm filter).

PE-CF594
BD Horizon™ PE-CF594 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496-nm and 566-nm and an acceptor dye with an emission maximum (Em Max) at 615-nm. PE-CF594, driven by BD innovation, 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 615 nm (e.g., a 610/20-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and the acceptor dye can be excited by the green (532-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
