FITC Rat Anti-Mouse IL-2
FITC Rat Anti-Mouse IL-2
Expression of IL-2 by stimulated CD4+ and CD4- BALB/c spleen cells. Splenocytes from 6 month-old BALB/C mice were stimulated for 5 hours with hamster anti-mouse CD3 (2 mg/ml final concentration; Cat. No.553057, clone 145-2C11) and hamster anti-mouse CD28 (2 mg/ml final concentration; Cat. No. 553294, clone 37.51) antibodies in the presence of BD GolgiStop™ (3 µM final concentration; Cat. No. 554724). The cells were harvested, stained with 0.06 µg of PE-conjugated rat anti-mouse CD4 (PE-RM4-5, Cat. No. 553049), fixed, permeabilized, and subsequently stained with 0.06 µg of FITC-conjugated rat anti-mouse IL-2 antibody (FITC-JES6-5H4, Cat. No. 554427) using Pharmingen's staining protocol (left panel). To demonstrate specificity of staining, the binding by FITC-JES6-5H4 was blocked by each of the following: 1) preincubation of the conjugated antibody with recombinant mouse IL-2 (0.12 mg, Cat. No. 550069; middle panel), and by 2) preincubation of the fixed/permeabilized cells with excess unlabelled JES6-5H4 antibody 2.5 mg; Cat. No. 554425; right panel) prior to staining with the FITC-JES6-5H4 antibody. The quadrant markers for the bivariate dot plots were set based on the autofluorescence controls and verified using the recombinant cytokine blocking and unlabelled antibody blocking specificity controls. A suitable rat IgG2b isotype control for assessing the level of background staining on fixed/permeabilized mouse cells is Cat. No. 556923; use at comparable concentrations to antibody of interest.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Assay Procedures

Recommended Assay Procedure:

Immunofluorescent Staining and Flow Cytometric Analysis: The JES6-5H4 antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IL-2 producing cells within mixed cell populations. FITC-, PE-, APC, Alexa Fluor® 488 and Alexa Fluor® 647 conjugated antibodies (Cat. No. 554427; Cat. No. 554428; Cat No. 554429, Cat. No. 557725 and Cat. No. 557736) are especially suitable for these studies.  

An appropriate rat IgG2b isotype control is Cat. No. 556923. A useful control for demonstrating specificity of staining is pre-blocking with one of the following: 1) recombinant mouse IL-2 (Cat. No. 550069) or 2) unlabeled JES6-5H4 antibody (Cat. No. 554425), prior to staining. For specific methodology, please visit the protocols section or chapter on intracellular staining in the Immune Function Handbook, both of which are posted on our web site, www.bdbiosciences.com.

JES6-5H4

The JES6-5H4 monoclonal antibody specifically binds to mouse interleukin-2 (IL-2), a multifunctional cytokine that plays pivotal roles in immunity and tolerance. It is produced by activated T cells and affects the activation, growth, proliferation and/or differentiation of various cell types including T and B lymphocytes and their precursors, LAK cells, NK cells, and monocytes/macrophages. IL-2 mediates its biological activities by binding to IL-2 receptor complexes. The intermediate affinity IL-2R is comprised of IL-2Rβ (CD122) and common gamma chain (γc; CD132) subunits, whereas the high-affinity IL-2R is comprised of IL-2Rα (CD25), IL-2Rβ, and γc subunits. The JES6-5H4 monoclonal antibody binds to IL-2 and neutralizes its biological activity.

This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

FITC
Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
