  • FunctionIGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
  • Tissue specificityExpressed by most tissues. Present in plasma.
  • Sequence similaritiesContains 1 IGFBP N-terminal domain.
    Contains 1 thyroglobulin type-1 domain.
  • Developmental stageIGFBP3 levels are higher during extrauterine life and peak during puberty.
  • DomainThe thyroglobulin type-1 domain mediates interaction with HN.
  • Post-translational
    Phosphorylation sites are present in the extracelllular medium.
  • Cellular localizationSecreted.

  • ab76001 at 1/50 dilution, staining IGFBP3 in human breast carcinoma tissue section by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections). The DAB staining procedure was used for detection.

  • ICC/IF image of ab76001 stained HeLa cells. The cells were 4% formaldehyde (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 (ab76001, 10µg/ml) overnight at +4°C. The secondary antibody (green) was 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.
