The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/10000 - 1/50000. Predicted molecular weight: 35 kDa.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function

      Inhibits IGF-mediated growth and developmental rates. 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.
    • Domain

      The C-terminus is required for IGF-binding and growth inhibition.
