Product Overview
Clone ADF-13 is a rabbit monoclonal antibody that recognizes mitogen-activated protein kinase 3 (gene MAPK3) in human and mouse samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 43.1 kDa, and the supplier reports an observed band at about 40 kDa.
ERK1 (MAPK3) is a serine/threonine kinase closely related to ERK2 at the end of the RAS–RAF–MEK–ERK cascade. Once activated by MEK1/2, it phosphorylates many cytoplasmic and nuclear targets that control proliferation, differentiation and survival, and dual phosphorylation of ERK1/2 is a standard marker of pathway activation.

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 breast carcinoma 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
Synthetic peptide based on the sequence of human ERK1.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places mitogen-activated protein kinase 3 in the cytoplasm, nucleus, membrane and cell junction. 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).
