Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 40 kDa (predicted molecular weight: 27 kDa).
IP 1/10 - 1/100.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Flow Cyt 1/100 - 1/1000.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


ICC/IF 1/250 - 1/500.


  • Function

    Heparin-binding protein, with mitogenic activity for fibroblasts. Acts as a transcriptional repressor.
  • Tissue specificity

  • Sequence similarities

    Belongs to the HDGF family.
    Contains 1 PWWP domain.
  • Domain

    The PWWP domain harbors the heparin-binding sites and is responsible for DNA-binding, while the C-terminal region is essentially unstructured.
  • Post-translational

    Sumoylated by SUMO1. Sumoylation prevents binding to chromatin.
  • Cellular localization

    Cytoplasm. Nucleus.
  • Information by UniProt
  • Database links

  • ab128921 staining HDGF in MCF-7 (human breast carcinoma) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% PFA and permeabilized with 0.1% triton X-100. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000.

    DAPI was used as a nuclear counterstain and the negative control was PBS only.

  • Overlay histogram showing HeLa cells stained with ab128921 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab128921, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
