      APC-Cy™7 Rat Anti-Mouse TNF
      APC-Cy™7 Rat Anti-Mouse TNF
      Flow cytometric analysis for TNF in activated mouse splenocytes.  Mouse Intracellular Cytokine-1 positive control cells (MiCK-1, Cat. No. 554652), are activated mouse splenocytes prepared in the presence of a protein transport inhibitor (Cat. No.555029). MiCK-1 cells were fixed and permeabilized with BD Cytofix/Cytoperm Plus Kit (Cat. No. 555028), then stained with either APC-Cy™7 Rat IgG1, κ isotype control (Cat. No. 560534, left panel) or APC-Cy™7 Rat Anti-Mouse TNF antibody (Cat. No. 560658, right panel).  Dot plots were derived from gated events based on light scattering characteristics for lymphocytes.  Flow cytometry was performed on a BD™ LSR II flow cytometry system.

      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 APC-Cy7 under optimum conditions, and unconjugated antibody and free APC-Cy7 were removed.

      Recommended Assay Procedures

      Flow cytometry:  The MP6-XT22 antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate TNF producing cells within mixed cell populations.  A useful control investigators may consider using for demonstrating specificity of staining, is to pre-block with one of the following reagents: (1) recombinant mouse TNF (Cat. No. 554589) or (2) unlabeled MP6-XT22 antibody (Cat. No. 554416), prior to staining.

      Cell Preparation: Investigators not wishing to utilize MiCK-1 cells may alternatively prepare mouse splenocytes (e.g BALB/c) stimulated for 4-6 hours with PMA (5 ng/mL, Sigma-Aldrich Cat. No. P-8139) and ionomycin (500 ng, Sigma-Aldrich Cat. No. I-0634) in the presence of 1 µg/mL Protein Transport Inhibitor [containing Brefeldin A] (Cat. No. 555029).  Investigators are advised to fix and permeabilize the cells with BD Cytofix/CytoPerm Plus Kit (Cat. No. 555028) prior to staining.

      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. Warning: Some APC-Cy7 and PE-Cy7 conjugates show changes in their emission spectrum with prolonged exposure to formaldehyde. If you are unable to analyze fixed samples within four hours, we recommend that you use BD™ Stabilizing Fixative (Cat. No. 338036).
      5. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
      6. APC-Cy7 tandem fluorochrome emission is collected in a detector for fluorescence wavelengths of 750 nm and higher.
      7. APC-Cy7 is a tandem fluorochrome composed of Allophycocyanin (APC), which is excited by laser lines between 595 and 647 nm and serves as an energy donor, coupled to the cyanine dye Cy7™, which acts as an energy acceptor and fluoresces at 780 nm. BD Biosciences Pharmingen has maximized the fluorochrome energy transfer in APC-Cy7, thus maximizing its fluorescence emission intensity, minimizing residual emission from APC, and minimizing required electronic compensation in multilaser-laser flow cytometry systems. Note: Although every effort is made to minimize the lot-to-lot variation in residual emission from APC, it is strongly recommended that every lot be tested for differences in the amount of compensation required and that individual compensation controls are run for each APC-Cy7 conjugate.
      8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

      MP6-XT22

      The MP6-XT22 antibody specifically binds to mouse Tumor Necrosis Factor (TNF, also known as TNF-α).  TNF is produced by many activated cell types including monocytes, macrophages, astrocytes, granulocytes, mast cells, T and B lymphocytes, NK cells, keratinocytes, fibroblasts, adipocytes, and certain tumor cells. Activated cells express type II transmembrane TNF glycoproteins that associate as homotrimeric complexes. After enzymatic cleavage, the extracellular regions of membrane TNF are shed as soluble homotrimers. TNF is a potent multifunctional cytokine that can exert regulatory and cytotoxic effects on a wide range of normal lymphoid and non-lymphoid cells and tumor cells. Although TNF serves as a primary mediator in protective immune responses against microbial and viral pathogens, it can also drive systemic pathophysiologic responses including septic shock, cachexia and autoimmune diseases. Mouse TNF exerts its biological activities by binding and signaling through cell surface membrane Type I and Type II TNF Receptors (aka, TNFRI/CD120a and TNFRII/CD120b, respectively).

      APC-Cy7
      APC-Cy7 dye is a part of the BD APC red family of dyes. This tandem fluorochrome is comprised of a Allophycocyanin (APC) donor that has excitation maxima (Ex Max) of 651 nm and an acceptor dye, Cy™7, with an emission maximum (Em Max) at 779 nm. APC-Cy7 can be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 780 nm (e.g., a 760/60 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
