Product Overview
This rabbit polyclonal antibody detects interleukin-6 (gene Il6) in rat and mouse samples and is validated for Western blot and IHC. The predicted molecular weight is 24.4 kDa, and the supplier reports an observed band at about 28–30 kDa.
Interleukin-6 (IL-6) is a multifunctional cytokine released by macrophages, dendritic cells and many other cells during infection and tissue injury. It binds IL-6R and then the signaling subunit gp130, activating JAK–STAT3 through classic or trans-signaling. IL-6 drives the acute phase response, B-cell differentiation and Th17 development, and it is one of the most widely measured inflammatory markers.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
Samples with a confirmed band (WB): recombinant rat IL6 protein, mouse spleen tissue, rat thymus tissue, rat spleen tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% 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): rat spleen 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 from the C-terminal region of rat IL6. It differs from the mouse sequence at two residues.
Reactivity Notes
The supplier lists reactivity with rat and mouse. UniProt describes interleukin-6 as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
