Expression of TNF protein by stimulated human peripheral blood mononuclear cells (PBMC). Human PBMC were stimulated for 6 hours with PMA (50 ng/ml final concentration; Sigma, Cat. #P-8139), calcium ionophore A23187 (0.5 µg/ml final concentration; Sigma, Cat. #C-9275) and PHA (Gibco BRL, Cat. #10576-015) in the presence of GolgiStop™ (2 µM final concentration; Cat. No. 554715). The PBMC were stained with 0.25 µg PE-Cy™5 Mouse Anti-Human CD3 (Cat. No. 555334) and subsequently stained with 0.5 µg of PE Mouse Anti-Human TNF (Cat. No. 554513/557068/559321/562083; left panel). To demonstrate specificity of staining, the binding of PE Mouse Anti-Human TNF was blocked by preincubation of the conjugate with excess (1 µg) recombinant human TNF (Cat. No. 554618; middle panel) and by preincubation of the fixed/permeabilized cells with an excess of Purified Mouse Anti-Human TNF (Cat. No. 554510; right panel) prior to staining with the PE Mouse Anti-Human TNF. The quadrant markers for the bivariate dot plot was set based on the negative staining controls using isotype-matched Ig controls.

Product Details

Brand: BD Pharmingen™

Alternative Name: Tumor necrosis factor alpha; TNF-a; TNF-α; TNFSF2; Cachectin

Reactivity: Human (QC Testing), Rhesus, Cynomolgus, Baboon (Tested in Development)

Isotype: Mouse IgG1, κ

Immunogen: Recombinant Human TNF

Application: Intracellular staining (flow cytometry) (Routinely Tested)

Concentration: 0.2 mg/ml

RRID: AB_395444

Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide.

Regulatory Status: RUO

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

Immunofluorescent Staining and Flow Cytometric Analysis: The MAb11 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify and enumerate TNF producing cells within mixed cell populations (see image). For optimal immunofluorescent staining with flow cytometric analysis, this anti-cytokine antibody should be pretitrated (≤ 1 µg mAb/million cells). The staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe. For specific methodology, please visit the protocols section under "Cytokines (Intracellular Staining)" or "Intracellular Flow" at our website, http://www.bdbiosciences.com/us/s/resources.

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.
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.

Antibody Details

MAb11

The MAb11 monoclonal antibody specifically binds to human tumor necrosis factor (TNF, also known as TNF-α) protein. TNF is an efficient juxtacrine, paracrine and endocrine mediator of inflammatory and immune functions. It regulates the growth and differentiation of a variety of cell types. TNF is cytotoxic for transformed cells when in conjunction with IFN-γ. It is secreted by activated monocytes/macrophages and other cells such as B cells, T cells and fibroblasts. The immunogen used to generate the MAb11 hybridoma was recombinant human TNF. The MAb11 antibody has been reported to crossreact with Rhesus Macaque TNF.

Format Details

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE 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 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Format: PE

Excitation Source: Yellow-Green 488 nm, 532 nm, 561 nm
