Product Overview
This rabbit polyclonal antibody recognizes dual specificity mitogen-activated protein kinase kinase 3 (gene MAP2K3) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 39.3 kDa, and the supplier reports an observed band at about 40 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.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
Samples with a confirmed band (WB): human HeLa cells, rat kidney tissue, mouse NIH/3T3 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, 30 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.
Samples with confirmed staining (IHC): human liver cancer tissue, human ovarian cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): Caco-2 cells.
Samples with a confirmed signal (flow cytometry): Caco-2 cells.
Immunogen
Synthetic peptide from the C-terminal region of human MEK3. The peptide sequence is conserved in mouse.
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.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
