Product Overview
This rabbit polyclonal antibody detects interferon gamma (gene Ifng) in rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 17.9 kDa, and the supplier reports an observed band at about 22 kDa.
Interferon gamma is the only type II interferon. It is produced mainly by activated T cells and NK cells, signals through IFNGR1/IFNGR2 and the JAK1/JAK2–STAT1 pathway, and activates macrophages and antigen presentation, making it a key readout of Th1 and cytotoxic immune responses.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Rat) |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
| Western blot | 0.1–0.5 µg/mL (Rat) |
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 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 1:10000, ECL detection.
Immunogen
E. coli-derived rat IFN gamma recombinant protein (Position: 23–156).
Reactivity Notes
The supplier lists reactivity with rat. UniProt describes interferon gamma as a secreted protein. Tissue expression noted by UniProt (rat): Released primarily from activated T lymphocytes. A carrier-free (BSA-free) format can be requested; specify it in the order note.

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).
