Product Overview
This rabbit polyclonal antibody recognizes CCN family member 2 (gene CCN2) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 38.1 kDa, and the supplier reports an observed band at about 38 kDa.
CCN2, better known as connective tissue growth factor (CTGF), is a secreted matricellular protein of the CCN family. It promotes fibroblast proliferation, matrix production, chondrocyte differentiation and bone formation, and it acts as a key downstream mediator of TGF-β signaling, making it a common marker in fibrosis, wound healing and skeletal research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human) |
Samples with a confirmed band (WB): rat liver tissue, rat thymus tissue, HeLa cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE, 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 mammary 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
Recombinant human CTGF fragment (Arg58–Ala349), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 95.5% and 95.9%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes CCN family member 2 as a secreted protein. Tissue expression noted by UniProt (human): Expressed in bone marrow and thymic cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
