Alternative Name: IFNG; Interferon-gamma; IFG; IFI; Type II interferon
Reactivity: Human (QC Testing), Rhesus, Cynomolgus, Baboon (Tested in Development)
Isotype: Mouse BALB/c IgG1, κ
Immunogen: Human IFN-γ from supernatants of S. aureus-stimulated PBMC
Application: Intracellular staining (flow cytometry) (Routinely Tested)
Concentration: 0.2 mg/ml
RRID: AB_395474
Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.
Regulatory Status: RUO
Preparation And Storage: Preparation And Storage Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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.
Recommended Assay Procedures: Recommended Assay Procedures Immunofluorescent Staining for Flow Cytometric Analysis: The PE Mouse Anti-Human IFN-γ antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IFN-γ producing cells within mixed cell populations. For optimal immunofluorescent staining for flow cytometric analysis, the anti-cytokine antibody should be titrated (≤ 0.5 µg mAb/million cells). For specific methodology, please visit our web site, http://www.bdbiosciences.com/us/s/resources, and go to the protocols section under "Intracellular Flow". A useful control for demonstrating specificity of staining is either of the following: 1) pre-block the PE Mouse Anti-Human IFN-γ antibody with ligand (e.g., rhIFN-γ, Cat. No. 554617) prior to staining, or 2) pre-block the fixed/permeabilized cells with Purified Mouse Anti-Human IFN-γ (Cat. No. 554549) prior to staining. The staining technique and blocking controls are described in detail by C. Prussin and D. Metcalfe. A suitable mouse IgG1 isotype control for assessing the level of background staining on paraformaldehyde-fixed/saponin-permeabilized human cells is PE Mouse IgG1, κ Isotype Control (Cat. No. 554680); use at comparable concentrations to antibody of interest (e.g., ≤ 0.5 µg mAb/1 million cells).
Product Notices: Product Notices Since applications vary, each investigator should titrate the reagent to obtain optimal results. An isotype control should be used at the same concentration as the antibody of interest. 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.
