BD, 561061, BD Pharmingen™ PE Rat Anti-Mouse IL-2

Reactivity: Mouse (QC Testing)
Isotype: Rat IgG2b
Immunogen: Mouse IL-2 Recombinant Protein
Application: Intracellular staining (flow cytometry) (Routinely Tested)
Concentration: 0.2 mg/ml
RRID: AB_395386
Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.
Regulatory Status: RUO
Preparation And Storage: Preparation And Storage The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Recommended Assay Procedures: Recommended Assay Procedures Recommended Assay Procedure: Immunofluorescent Staining for Flow Cytometric Analysis: The PE conjugated JES6-5H4 antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IL-2 producing cells within mixed cell populations. For optimal immunofluorescent staining for flow cytometric analysis this antibody should be titrated.  For specific methodology, please visit our web site, www.bdbiosciences.com, and go to the protocols section or to the chapter on intracellular staining in the Immune Function Handbook. A useful control for demonstrating specificity of staining is either of the following: 1) pre-block the PE-conjugated JES6-5H4 antibody with ligand (e.g., recombinant mouse IL-2, Cat No. 550069) prior to staining, or 2) pre-block the fixed/permeabilized cells with unlabeled JES6-5H4 antibody (Cat. No. 554425) prior to staining. The staining technique and blocking controls are described in detail by C. Prussin and D. Metcalfe. A suitable rat IgG2b isotype control for assessing the level of background staining on paraformaldehyde-fixed/saponin-permeabilized mouse cells is PE-A95-1 (Cat. No. 556925); use at comparable concentrations to antibody of interest.
Product Notices: Product Notices Since applications vary, each investigator should titrate the reagent to obtain optimal results. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols. 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.
