PE Mouse anti-TBK1
PE Mouse anti-TBK1
Analysis of TBK1 in transfected human epithelial cells.  The 293 fetal kidney cell line (left panel) was either co-transfected with TBK1 and IRF-7 expression vectors (dashed histogram) or un-transfected (solid line).  After 24 hours, the cells were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 10 minutes at 37°C, then permeabilized (BD Phosflow™  Perm Buffer III, Cat. No. 558050) on ice for at least 30 minutes, and then stained with PE Mouse anti-TBK1 (Cat. No. 558696).  Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.  The specificity of mAb 637Ig11.2 was confirmed by western blot (right panel) using unconjugated antibody on lysates from untransfected (left panel) and TBK1/IRF-7 co-transfected (right panel) 293 cells.  The TBK1-Myc tagged fusion protein is identified as a band of 84 kDa in the lysate of co-transfected cells.

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.

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

637Ig11.2

NF-κB is a ubiquitously expressed transcription factor that regulates many cytokine and Ig genes.  It is involved in immune, inflammatory, viral, and acute phase responses.  In most cells, NF-κB is sequestered in an inactive cytoplasmic form via interactions with the inhibitory proteins IκBα, IκBβ, and IκBε.  Stimulation induces the release, activation, and nuclear translocation of NF-κB.  Release of NF-κB results from the phosphorylation and proteolytic degradation of the IκB proteins.  Two cytokine-inducible IκB kinases (IKKα and IKKβ) phosphorylate and target the IκB proteins for degradation via the ubiquitin pathway.  IKKγ/NEMO, a third member of the IKK complex, functions as a regulatory subunit and interacts directly with IKKβ.  TBK1 (TANK-binding kinase 1, also known as T2K or NAK), a protein of 729 amino acids, is another member of the IKK family of kinases regulating NF-κB downstream of the tumor necrosis factor and Toll-like receptor pathways.  TBK1 forms a complex with the adaptor proteins TANK (TRAF-associated NF-κB activator) and TRAF2 (TNF-receptor-associated factor 2), and this oligomer is required for activation and phosphorylation of TBK1 at serine 172.

The 637Ig11.2 monoclonal antibody recognizes human TBK1, regardless of phosphorylation status.  Our in-house testing is performed on a cell line that has been co-transfected with TBK1 and IRF-7 because we have been unable to detect endogenous TBK1 by western blotting of lysates from activated cell lines (HeLa activated with PMA and A431 activated with PDGF).  In the transfectants, the over-expression of TBK1 is necessary for phosphorylation of IRF-7, but the presence of IRF-7 does not affect TBK1 expression or phosphorylation.  We confirmed that mAb 637Ig11.2 does not cross-react with IRF-7 by western blot analysis using the purified antibody.

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.
