BD Pharmingen™ PE Hamster Anti-Rat/Mouse TNF
クローン TN3-19.12 (RUO)
Expression of TNF by RiCK-2 Positive control cells. In vitro differentiated and re-stimulated LOU lymphocytes (RiCK-2 Cells, Cat. No. 555094) were fixed, permeabilized, and subsequently stained with PE-conjugated rat anti-mouse TNF antibody (PE-TN3-19.12, Cat. No. 559503) by using Pharmingen's staining protocol (see Figure, left panel). To demonstrate specificity of staining, the binding of PE-TN3-19.12 was blocked by the preincubation of the conjugated antibody with molar excess of recombinant rat TNF (0.25 µg, Cat. No. 555109; middle panel), and by preincubation of the fixed/permeabilized cells with an excess of the unlabeled TN3-19.12 mAb (5µg, Cat. No. 557516; right panel). The quadrant markers for the bivariate dot plots were set based on the autofluorescence control, and verified with the recombinant cytokine blocking (middle panel) and unlabeled antibody blocking specificity controls.

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.
推奨アッセイ手順
The PE-conjugated TN3-19.12 antibody can be used for multicolor immunofluorescent staining and flow cytometric analyses to identify and enumerate rat 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 our web site, www.bdbiosciences.com, and go to the protocols section or 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 conjugated TN3-19.12 antibody with a molar excess of ligand prior to staining, or 2) pre-block the fixed/permeabilized cells with unconjugated TN3-19.12 antibody (Cat. No. 557516) prior to staining. The staining technique and blocking controls are described in detail by C. Prussin and D. Metcalfe. A suitable hamster IgG1, λ isotype control for assessing the level of background staining on paraformaldehyde-fixed/saponin-permeabilized mouse and human cells is PE-G235-2356 (Cat. No. 554711); use at comparable concentrations to antibody of interest (e.g., ≤ 0.5 µg mAb/ 1 million cells).
OTHER APPLICATIONS
In vitro neutralization: The NA/LE™ format of the TN3-19.12 antibody (Cat. No. 557370) is useful for neutralization of mouse TNF bioactivity.
IP/WB: The TN3-19.12 antibody has been reported to be useful for immunoprecipitation and Western blot. Please note that this application is not routinely tested at BD Biosciences Pharmingen.
ELISA: The purified TN3-19.12 antibody (Cat. No. 557516) can be used as a capture antibody for a sandwich ELISA that measures TNF protein levels.
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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- 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.

TN3-19.12
The TN3-19.12 antibody reacts with rat and mouse tumor-necrosis factor (TNF) proteins (also known as TNF-α) . Moreover, the TN3-19.12 antibody is reported to crossreact with rabbit TNF, but it does not crossreact with mouse lymphotoxin-α (LT-α, also known as TNF-β) nor with human TNF. The immunogen used to generate the TN3-19.12 hybridoma was E. coli-expressed, purified recombinant mouse TNF protein. This monoclonal antibody has been reported to neutralize the bioactivities of mouse, rat and rabbit TNF.
This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

PE
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.
