Product Overview
This rabbit polyclonal antibody recognizes transcription factor Jun in human samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 35.7 kDa, and the supplier reports an observed band at about 36 kDa.
c-Jun (JUN) is a bZIP transcription factor and core component of AP-1. It forms dimers with Fos family proteins and other partners to bind TRE (TGA[GC]TCA) sites and control genes involved in proliferation, differentiation, stress responses and apoptosis. Its activity is strongly increased by JNK phosphorylation, and it is a widely used readout in studies of cell signaling and cancer.

Samples with a confirmed band (WB): human HeLa cells, human K562 cells, human Jurkat cells, human U-87MG 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, 30 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 renal cells carcinoma tissue, human the renal pelvis squamous metaplasia 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).
Samples with confirmed staining (ICC/IF): A431 cells.
Samples with a confirmed signal (flow cytometry): U2OS cells.
Immunogen
Recombinant human c-Jun/JUN fragment (Lys35–Phe331), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places transcription factor Jun in the nucleus. Tissue expression noted by UniProt (human): Expressed in the developing and adult prostate and prostate cancer cells. 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).
