Product Overview
Clone 29M34 is a rabbit monoclonal antibody that recognizes mitogen-activated protein kinase 8 (gene MAPK8) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 48.3 kDa, and the supplier reports an observed band at about 45 kDa.
JNK1 (MAPK8) is a stress-activated serine/threonine kinase of the c-Jun N-terminal kinase family. Cytokines, UV light and other stresses switch it on through the upstream kinases MKK4 and MKK7, after which it phosphorylates c-Jun, ATF2 and other AP-1 components. It is widely studied in apoptosis, inflammation, T-helper cell differentiation and metabolic stress.

Validated Applications
| Western blot | 1:500–1:2000 |
|---|---|
| Immunohistochemistry | 1:50–1:200 |
Samples with a confirmed band (WB): human 293T cells, human HeLa cells, human Jurkat cells, human A431 cells, rat brain tissue, rat C6 cells, mouse brain tissue.
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 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:1000, ECL detection.
Samples with confirmed staining (IHC): human colorectal adenocarcinoma tissue, human liver cancer tissue, human lung cancer tissue, human prostate 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
Synthetic peptide based on the sequence of human JNK1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places mitogen-activated protein kinase 8 in the cytoplasm, nucleus and synapse. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
