Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -20°C. Store under desiccating conditions.

    Constituent: 99% PBS

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

  • Reconstitution
    It is recommended to reconstitute ab125753 in sterile ultra pure water not less than 100µg/ml, which can then be further diluted to other aqueous solutions. Upon reconstitution ab125753 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

  • Function
    IGF-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.
  • Sequence similarities
    Contains 1 IGFBP N-terminal domain.
    Contains 1 thyroglobulin type-1 domain.
  • Cellular localization
    Secreted.
  • Information by UniProt
