BD Pharmingen™ FITC Mouse Anti-Human TNF

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

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.

Product Notices

1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. An isotype control should be used at the same concentration as the antibody of interest.
3. 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.
4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
5. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
6. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
