Catalog#:3597
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-kappaB, which is a pivotal transcription factor mediating inflammatory and immune response. A novel member in the IRAK/Pelle family has been identified and designated IRAK2 (1). Both IRAK and IRAK2 recruit to the subunits of the IL-1R complex after IL-1 binding and lead to NF-kappaB activation. IRAKs also associate with Toll like receptor (TLR) and the dominant negative mutants of IRAKs inhibit LPS-induced NF-?B activation (2,3). Members in IRAK/Pelle family play a central role in IL-1R and TLR mediated inflammatory response. Unlike human IRAK2, murine IRAK2 exists as four alternately spliced isoforms (IRAK2a-d), with two isoforms (IRAK2c and d) acting in an inhibitory fashion (4). IRAK2 is expressed in a variety of tissues.
Additional Names: IRAK2 (C2), mIRAK2
Description
Left: Western blot analysis of IRAK2 in A-20 whole cell lysate with IRAK2 antibody (C2) at (A) 0.5, (B) 1, and (C) 2 µg/ml.
Source:RAK2 antibody was raised against a peptide corresponding to 16 amino acids near the carboxy-terminus of mouse IRAK2a which is common to all four isoforms. Anti-IRAK2 is mouse specific.
Purification: Affinity chromatography purified via peptide column
Clonality and Clone: This is a polyclonal antibody.
Host: IRAK2 antibody was raised in rabbit.
Please use anti-rabbit secondary antibodies.
Immunogen: Human IRAK2 (C-Terminus 2) Peptide (Cat. No. 3597P)
Application: IRAK2 antibody can be used for detection of mouse IRAK2 by Western blot at 0.5 - 1 µg/ml.Anti-IRAK2 has no cross response to IRAK.
Tested Application(s): E, WB
