Peptide corresponding to aa700-712, DRQGPEESDEFQS of human IRAK.
The pro-inflammatory cytokine IL-1 induces cellular response through two subunits of its receptor, IL-1 receptor I (IL-1RI) and IL-1 receptor accessory protein (IL-1RAcP). IL-1 receptor-associated kinase (IRAK) mediates activation of NF-kB, which is a pivotal transcription factor mediating inflammatory and immune response. A novel member in the IRAK/Pelle family was recently identified and designated IRAK2. Both IRAK and IRAK2 recruit to the subunits of the IL-1R complex after IL-1 binding and lead to NF-kB activation. IRAKs also associate with Toll like receptor (TLR) and the dominant negative mutants of IRAKs inhibit LPS-induced NF-kB activation. Members in IRAK/Pelle family play a central role in IL-1R and TLR mediated inflammatory responses to cytokine IL-1 and LPS. IRAK2 is expressed in a variety of human tissues. Applications: Suitable for use in Western Blot and Immunoprecipitation. Other applications have not been tested. Recommended Dilutions: Western Blot: 0.5-2ug/ml detects IRAK in HeLa nuclear extract. HeLa nuclear extract was resolved by electrophoresis, transferred to nitrocellulose and probed with I8600-05 (1ug/ml). Proteins were visualized using an IgG (HRP) goat anti-rabbit secondary antibody and a chemiluminescence detection system. Immunoprecipitation: 4ug immunoprecipitates IRAK from 500ug of HeLa nuclear extract. Optimal dilutions to be determined by the researcher. Positive Control Included: H1838: HeLa nuclear extract. Add an equal volume of Laemmli reducing sample buffer to 5-10ul of extract and boil for 5 minutes to reduce the preparation. Load 10- 20ug/lane for minigels. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
