Product Overview
Clone HDB-13 is a rabbit monoclonal antibody that recognizes dual specificity mitogen-activated protein kinase kinase 3 (gene MAP2K3) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 39.3 kDa, and the supplier reports an observed band at about 39 kDa.
MKK3 (MAP2K3) is a dual-specificity kinase activated by cytokines and cellular stress. It phosphorylates and activates p38 MAP kinases on a threonine and a tyrosine, driving stress and inflammatory responses, and it is studied in inflammation, cell stress and immune signaling.

Samples with a confirmed band (WB): human HepG2 cells, human HeLa cells, mouse NIH/3T3 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human liver tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Synthetic peptide based on the sequence of human MEK3.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. Tissue expression noted by UniProt (human): Abundant expression is seen in the skeletal muscle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
