BD, 554512, BD Pharmingen™ FITC Mouse Anti-Human TNF

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: Flow cytometry (Routinely Tested)
Concentration: 0.5 mg/ml
RRID: AB_395443
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 FITC under optimum conditions, and unreacted FITC was removed.
Recommended Assay Procedures: Recommended Assay Procedures The FITC-conjugated MAb11 antibody can be used for multicolor immunofluorescent staining and flow cytometric analyses to identify and enumerate TNF-producing cells within mixed cell populations (see figure). For optimal immunofluorescent staining with flow cytometric analysis, this anti-cytokine antibody should be titrated (≤ 0.5 µg mAb/million cells)   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. A useful control for demonstrating specificity of staining is either of the following: 1) pre-block the conjugated MAb11 antibody with a molar excess of ligand (e.g., recombinant human TNF; Cat No. 554618) prior to staining, or 2) pre-block the fixed/ permeabilized cells with unlabelled MAb11 antibody (Cat. No. 554510) 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 FITC-MOPC-21 (Cat. No. 554679); use at comparable concentrations to antibody of interest.
