The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/5000 - 1/20000. Detects a band of approximately 40 kDa (predicted molecular weight: 39 kDa).
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
Is unsuitable for ICC or IHC.
Dual specificity kinase. Is activated by cytokines and environmental stress in vivo. Catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in the MAP kinase p38.
Abundant expression is seen in the skeletal muscle. It is also widely expressed in other tissues.
Note=Defects in MAP2K3 may be involved in colon cancer.
Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily. Contains 1 protein kinase domain.
Autophosphorylated. Phosphorylation on Ser-218 and Thr-222 by MAP kinase kinase kinases regulates positively the kinase activity. Yersinia yopJ may acetylate Ser/Thr residues, preventing phosphorylation and activation, thus blocking the MAPK signaling pathway.

Western blot - Anti-MEK3 antibody [EP555Y] (ab40836)
Predicted band size : 39 kDa
Lane 1: Wild-type HAP1 cell lysate (20 µg) Lane 2: MEK3knockout HAP1 cell lysate (20 µg) Lane 3: HeLa cell lysate (20 µg) Lane 4: Jurkat cell lysate (20 µg) Lanes 1 - 4: Merged signal (red and green). Green - ab40836 observed at 150 kDa. Red - loading control, ab8245, observed at 37 kDa. ab40836 was shown to recognize MEK3 when MEK3 knockout samples were used, along with additional cross-reactive bands. Wild-type and MEK3 knockout samples were subjected to SDS-PAGE. ab40836 and ab8245 (loading control to GAPDH) were both diluted to 1/5000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
