Product Overview
This rabbit polyclonal antibody targets mitogen-activated protein kinase 7 (gene MAPK7) in human, monkey, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 88.4 kDa, and the supplier reports an observed band at about 115–120 kDa.
ERK5 (MAPK7), also called big MAP kinase 1, is activated specifically by MEK5 in response to growth factors and cellular stress. Once active it moves to the nucleus and phosphorylates targets such as MEF2 transcription factors, and it is important for cardiovascular development, endothelial function and cell survival.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat, Monkey) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human K562 cells, human Hek293 cells, human HeLa cells, monkey Cos-7 cells, rat brain tissue, mouse brain 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, 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.
Samples with confirmed staining (IHC): human breast cancer tissue, human lung 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).
Immunogen
Recombinant human ERK5/MAPK7 fragment (Lys22–Pro816), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, monkey, mouse and rat. UniProt places mitogen-activated protein kinase 7 in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Expressed in many adult tissues. 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).
