Flow cytometric analysis of human PBMCs using Toll-like Receptor 9 (D9M9H) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate) co-stained with anti-CD11c (dendritic cell) and anti-CD3 (T cell) antibodies. Toll-like receptor 9 is clearly expressed on the CD11c+ dendritic cell population (left) and absent on the CD3+ T cells (right). The standard flow cytometry protocol was carried out using 50% methanol permeabilization (instead of 90%) to preserve cell surface epitopes.Learn more about how we get our images.
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.

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 antibody. Protect from light. Do not freeze.
Toll-like Receptor 9 (D9M9H) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate) recognizes endogenous levels of total Toll-like receptor 9 protein. This antibody is predicted to recognize known full-length isoforms of Toll-like receptor 9, but not cleaved Toll-like receptor 9 protein.
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro450 of human Toll-like receptor 9 protein.
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 647 fluorescent dye 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 Toll-like Receptor 9 (D9M9H) XP® Rabbit mAb #13674.
Members of the Toll-like receptor (TLR) family, named for the closely related Toll receptor in Drosophila, play a pivotal role in innate immune responses (1-4). TLRs recognize conserved motifs found in various pathogens and mediate defense responses (5-7). Triggering of the TLR pathway leads to the activation of NF-κB and subsequent regulation of immune and inflammatory genes (4). The TLRs and members of the IL-1 receptor family share a conserved stretch of approximately 200 amino acids known as the Toll/Interleukin-1 receptor (TIR) domain (1). Upon activation, TLRs associate with a number of cytoplasmic adaptor proteins containing TIR domains, including myeloid differentiation factor 88 (MyD88), MyD88-adaptor-like/TIR-associated protein (MAL/TIRAP), Toll-receptor-associated activator of interferon (TRIF), and Toll-receptor-associated molecule (TRAM) (8-10). This association leads to the recruitment and activation of IRAK1 and IRAK4, which form a complex with TRAF6 to activate TAK1 and IKK (8,11-14). Activation of IKK leads to the degradation of IκB, which normally maintains NF-κB in an inactive state by sequestering it in the cytoplasm.
