Product Overview
This rabbit polyclonal antibody detects inhibitor of nuclear factor kappa-B kinase subunit epsilon (gene IKBKE) in human samples and is validated for Western blot and ELISA. The predicted molecular weight is 80.5 kDa, and the supplier reports an observed band at about 80 kDa.
IKKε (IKBKE, also called IKKi) is a non-canonical IκB kinase related to TBK1. After viral RNA or DNA sensing, it phosphorylates IRF3 and IRF7 to switch on type I interferon genes, and it also contributes to NF-κB and STAT signaling, linking it to antiviral immunity and inflammation.

Samples with a confirmed band (WB): human HL-60 cells, human U-87MG cells, human A549 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant human IKKi/IKKe/IKBKE fragment (Gln318–Val716), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places inhibitor of nuclear factor kappa-B kinase subunit epsilon in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Highly expressed in spleen followed by thymus, peripheral blood leukocytes, pancreas, placenta. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
