    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized product in sterile deionized water to a final concentration of 1 mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long-term storage.

  • Function

    The insulin-like growth factors possess growth-promoting activity. In vitro, they are potent mitogens for cultured cells. IGF-II is influenced by placental lactogen and may play a role in fetal development.
    Preptin undergoes glucose-mediated co-secretion with insulin, and acts as physiological amplifier of glucose-mediated insulin secretion. Exhibits osteogenic properties by increasing osteoblast mitogenic activity through phosphoactivation of MAPK1 and MAPK3.
  • Involvement in disease

    Epigenetic changes of DNA hypomethylation in IGF2 are a cause of Silver-Russell syndrome (SIRS) [MIM:180860]. SIRS is a clinically heterogeneous condition characterized by severe intrauterine growth retardation, poor postnatal growth, craniofacial features such as a triangular shaped face and a broad forehead, body asymmetry, and a variety of minor malformations.
  • Sequence similarities

    Belongs to the insulin family.
  • Post-translational

    O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localization

  • Information by UniProt


  • SDS-PAGE analysis of ab246181 under reducing (Lane 1) and non-reducing (Lane 2) conditions.

    The protein has a calculated MW of 35.4 kDa. As a result of glycosylation, the protein migrates as 40 kDa under reducing conditions, and 66 kDa under non-reducing conditions.

  • Immobilized Human IGFBP-3, His Tag at 5 μg/mL (100 μl/well) can bind ab246181 with a linear range of 0.008-0.1 μg/mL.
