Flow cytometric analysis of THP-1 cells, untreated (blue) or treated with TPA (200 nM, 4D/3D rest) and LPS (1 ug/ml, 1 hr; green) using Phospho-TBK1/NAK (Ser172) (D52C2) XP® Rabbit mAb (PE Conjugate) (solid lines) or concentration-matched Rabbit (DA1E) mAb IgG XP® Isotype Control (PE Conjugate) #5742 (dashed lines).
This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometry analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated Phospho-TBK1/NAK (Ser172) (D52C2) XP® Rabbit mAb #5483.
Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibodies. Protect from light. Do not freeze.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to fixation.

Phospho-TBK1/NAK (Ser172) (D52C2) XP® Rabbit mAb (PE Conjugate) recognizes endogenous levels of TBK1 only when phosphorylated at Ser172. This antibody may cross-react with phospho-IKKε.Species Reactivity:
Human, MouseSpecies predicted to react based on 100% sequence homology:
Mouse, Rat, Monkey, Xenopus, Bovine, Dog
Monoclonal antibody is prepared from animals immunized with a synthetic phosphopeptide corresponding to residues surrounding Ser172 of human TBK1 protein.
TBK1 (TANK-binding kinase 1)/NAK (NF-κB activating kinase) is an IκB kinase (IKK)-activating kinase and can activate IKK through direct phosphorylation (1). TBK1 was identified through association with the TRAF binding protein, TANK, and found to function upstream of NIK and IKK in the activation of NF-κB (2). TBK1 induces IκB degradation and NF-κB activity through IKKβ. TBK1 may mediate IKK and NF-κB activation in response to growth factors that stimulate PKCε activity (1). TBK1 plays a pivotal role in the activation of IRF3 in the innate immune response (3).
