Product Overview
This rabbit polyclonal antibody detects mitogen-activated protein kinase 9 (gene MAPK9) in human, mouse and rat samples and is validated for Western blot, ICC/IF and flow cytometry. The predicted molecular weight is 48.1 kDa, and the supplier reports an observed band at about 48–50 kDa.
JNK2 (MAPK9) is a close relative of JNK1 in the c-Jun N-terminal kinase branch of MAP kinase signaling. Activated by inflammatory cytokines and cellular stress, it phosphorylates c-Jun and other transcription factors to shape gene expression, and it often shares or balances roles with JNK1 in cell death, immune responses and stress adaptation.

Immunogen
Synthetic peptide from the middle region of human JNK2. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places mitogen-activated protein kinase 9 in the cytoplasm and nucleus. 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).
