  • 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.

  • ab5097 staining CTGF in human bronchus tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections).
    Tissue was fixed in formaldehyde and an antigen retrieval step was performed using EDTA pH9.0. Samples were then incubated with ab5097 at a 1/400 dilution for 20 minutes at 25°C. The secondary used was an undiluted HRP conjugated goat anti-mouse/rabbit polyclonal.

  • ICC/IF image of ab5097 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab5097 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • ab5097 staining CTGF in human heart tissue section by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue underwent fixation in formaldehyde, heat mediated antigen retrieval in buffer and blocking (5 minutes/peroxidase block then 10 minutes/protein block) for 15 minutes at 20°C. The primary antibody was diluted, 1/50 and incubated with sample for 45 minutes at 20°C. A HRP conjugated goat polyclonal to rabbit IgG was used undiluted as secondary.

  • ab5097 staining CTGF in Human Hela, cervix cancer cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.2% Triton X-100 in PBS and blocked with 1% normal goat serum for 30 minutes. Samples were incubated with primary antibody (1/750) for 4 hours at 20°C. A Cy3®-conjugated Goat anti-rabbit polyclonal was used as the secondary antibody (1/800).

  • ab5097 staining CTGF in Pig skin tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 3% BSA for 2 hours at 25°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/200 in blocking buffer) for 24 hours at 4°C. A BHRP-conjugated Goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.

  • ab5097 staining CTGF in Pig skin tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with formaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 5% serum for 1 hour at 20°C. Samples were incubated with primary antibody (1/200 in PBS Tween 0.01% + donkey serum 1%) for 16 hours at 4°C. An Alexa Fluor®488-conjugated Donkey anti-rat IgG polyclonal (1/500) was used as the secondary antibody.
