Applications
  •  
    Recommended
    Concentration
    Sample
  • Western Blot
    1 µg/mL
    See below
  • Knockout Validated
    MEKK3 is specifically detected in HeLa human cervical epithelial carcinoma parental cell line but is not detectable in MEKK3 knockout HeLa cell line.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Detection of Human MEKK3 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, Daudi human Burkitt's lymphoma cell line, and A431 human epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human MEKK3 Monoclonal Antibody (Catalog # MAB6095) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for MEKK3 at approximately 71 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
Knockout Validated
Western Blot Shows Human MEKK3 Specificity by Using Knockout Cell Line. Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and MEKK3 knockout HeLa cell line (KO). PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human MEKK3 Monoclonal Antibody (Catalog # MAB6095) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for MEKK3 at approximately 75 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockoutHeLa cell line. GAPDH (Catalog # MAB5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: MEKK3

MAPK/ERK kinase kinase 3 (MEKK3), also known as MEK kinase 3 and MAP3K3, is a widely expressed 71 kDa Ser/Thr kinase in the SEK, MEK, and MyD88‑IRAK‑TRAF6 signal transduction pathways. It contains a PB1 domain (aa 45‑123), a region with several phosphorylation sites, and a protein kinase domain (aa 361‑621). MEKK3 is involved in tissue morphogenesis, inflammation, and the response to cellular stress. Its activation leads to the activation of NF kappa B following stimulation of IL-1 R, TLR4, TLR8, TNF RI, and the AT1 angiotensin receptor.
