  • Function

    Major connective tissue mitoattractant secreted by vascular endothelial cells. Promotes proliferation and differentiation of chondrocytes. Mediates heparin- and divalent cation-dependent cell adhesion in many cell types including fibroblasts, myofibroblasts, endothelial and epithelial cells. Enhances fibroblast growth factor-induced DNA synthesis.
  • Tissue specificity

    Expressed in bone marrow and thymic cells. Also expressed one of two Wilms tumors tested.
  • Sequence similarities

    Belongs to the CCN family.
    Contains 1 CTCK (C-terminal cystine knot-like) domain.
    Contains 1 IGFBP N-terminal domain.
    Contains 1 TSP type-1 domain.
    Contains 1 VWFC domain.
  • Cellular localization

  • CTGF was immunoprecipitated from 0.35 mg HepG2 (human hepatocellular carcinoma epithelial cell) whole cell lysate with ab209780 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab209780 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.
    Lane 1: HepG2 (human hepatocellular carcinoma epithelial cell) whole cell lysate 10 µg (Input).
    Lane 2: ab209780 IP in HepG2 whole cell lysate (+).
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab209780 in HepG2 whole cell lysate (-).
    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 3 minutes.

    The molecular mass observed is consistent with the literature. (PMID:27126736)

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab209780).

  • All lanes : Anti-CTGF antibody [EPR20728] (ab209780) at 1/1000 dilution

    Lane 1 : NIH/3T3 (mouse embryonic fibroblast) starved for 18 hours, whole cell lysate
    Lane 2 : NIH/3T3 starved for 18 hours, then treated with 10 ng/ml transforming growth factor-ß (TGF-ß1, ab50036) and 50 µg/ml Heparin sodium salt for 24 hours, whole cell lysate
    Lane 3 : HepG2 (human hepatocellular carcinoma epithelial cell), whole cell lysate

    Lysates/proteins at 20 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution

    Predicted band size: 38 kDa

    Blocking/Dilution buffer and concentration: 5% NFDM/TBST.

    The level of CTGF expression can be induced by TGFß treatment (PMID: 17786299).

    CTGF is constitutively expressed in HepG2 cells (PMID:15886528).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab209780).
