Analysis of IRAK4 in activated human peripheral blood lymphocytes (far left panel). Human peripheral blood mononuclear cells (PBMC) were lysed and fixed with 1X BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) for 10 minutes at 37ºC, then permeabilized (BD Phosflow™ Perm Buffer III, Cat. No. 558050) on ice for 30 minutes, and then stained with either Alexa Fluor® 647 Mouse IgG1 κ Isotype control (Cat. No. 557783, shaded histogram) or Alexa Fluor® 647 Mouse anti-Human IRAK4 (Cat. No. 560315, open histogram). For data analysis, lymphocytes were selected by scatter profile. Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system. Analysis of IRAK4 in human epithelioid carcinoma (center left panel). HeLa S3 cells (ATCC CCL 2.2) were either transfected with IRAK4 RNAi-transfected HeLaS3 cells (open histogram) or untreated (shaded histogram). The cells were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 10 minutes at 37°C, then permeabilized (BD Phosflow™ Perm Buffer III) on ice for 30 minutes, and then stained with Alexa Fluor® 647 Mouse anti-Human IRAK4. Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system. Confirmation of the specificity of mAb L29-525 by western blot analysis (center right panel). Lysates of human PBMC were probed with unconjugated antibody at a concentration of 0.1 µg/ml. IRAK4 is identified as a band of about 52 kDa. Western blot validation of IRAK4 by RNAi (far right panel). Lysates from HeLa S3 cells (lane 1) and IRAK4 RNAi-transfected HeLa S3 cells (lane 2) were probed with unconjugated mAb L29-525 at 0.015 µg/ml. Down-regulation of IRAK4 expression is evident in the RNAi-transfected cells.

Preparation and Storage
推奨アッセイ手順
This antibody conjugate is suitable for intracellular staining of human peripheral blood mononuclear cells and cell lines (using BD Phosflow™ Lyse/Fix Buffer or BD Cytofix™ Fixation Buffer), but not human whole blood. BD Phosflow™ Perm Buffer II or Perm Buffer III may be used.
Product Notices
- 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).
- An isotype control should be used at the same concentration as the antibody of interest.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

Interleukin 1 (IL-1) is a proinflammatory cytokine that mediates the host inflammatory response. IL-1 exerts its biological effects through its type I receptor (IL-1RI), which is found on most cell types. When IL-1 binds to the IL-1RI, NF-κB (transcription factor) is activated and translocates to the nucleus where it induces gene expression. IL-1-receptor-associated kinase (IRAK) has been reported to co-immunoprecipitate with IL-1RI. The IRAK family is made up of four identified Pelle homologs that regulate the activation of NF-κB and mitogen-activated protein (MAP) kinase pathways. IRAK4 is a unique member of the IRAK family because it is the closest mammalian homolog to Pelle. Also, when overexpressed, its kinase activity allows it to activate both the NF-κB and mitogen-activated protein (MAP) kinase pathways, and block the IL-1-induced activation and modification of IRAK1. IRAK4 is also able to phosphorylate IRAK1, which suggests that IRAK4 affects the early signal transduction of Toll/IL-1 receptors before the involvement of IRAK1.
The L29-525 monoclonal antibody recognizes human IRAK4, regardless of phosphorylation status. The specificity of this antibody conjugate for flow cytometric analysis was validated by confirming that RNA-mediated interference (RNAi) of the specific protein reduced the staining of the cells (see figure). Furthermore, the capacity of the RNAi to down-regulate the expression of the relevant protein was confirmed by western blot analysis.
