Product Overview
This rabbit polyclonal antibody recognizes interferon regulatory factor 3 isoform X1 (gene irf3) in zebrafish samples and is validated for Western blot.
Interferon regulatory factor 3 (IRF3) is a transcription factor that drives type I interferon production during viral infection. Sensing pathways such as RIG-I/MAVS, cGAS–STING and TLR3/4–TRIF activate the kinase TBK1, which phosphorylates IRF3 so it can dimerize, enter the nucleus and induce IFN-β and interferon-stimulated genes.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Zebrafish) |
|---|
Samples with a confirmed band (WB): zebrafish head tissue, whole female zebrafish tissue, whole male zebrafish tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
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 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant zebrafish IRF3 fragment (Ser92–Leu312), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with zebrafish. UniProt places interferon regulatory factor 3 isoform X1 in the 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).
