Storage Comment: The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. Confirmation of the specificity of mAb L29-525 by western blot analysis (left 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 (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.

Background: 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-kappaB (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-kappaB 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-kappaB 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.
