Product Overview
Clone ACE-13 is a rabbit monoclonal antibody that recognizes mitogen-activated protein kinase 3 (gene MAPK3) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 43.1 kDa, and the supplier reports an observed band at about 44 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.

Validated Applications
| Western blot | 1:500–1:2000 |
|---|---|
| Immunohistochemistry | 1:50–1:200 |
Samples with confirmed staining (IHC): human bladder 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 ERK1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. 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).
