IGF-BP6

• Description:

  IGF-BPs controls the distribution, function and activity of IGFs in various cell tissues and body fluids. IGF-BP6 is produced by bone cells and is the major IGF-BP present in cerebrospinal fluid, and specifically inhibits IGF-II actions. IGF-BP6 has been shown to inhibit IGF-II-dependent cancers such as neuroblastoma, colon cancer and rhabdomyosarcoma. Recombinant human IGF-BP6 has a calculated mass of 22.6 kDa and consists of 213 amino acid residues including the IGF-BP domain and thyroglobulin type-I domain. IGF-BP6 migrates at an apparent molecular weight of approximately 23.0-30.0 kDa by SDS-PAGE analysis under non-reducing conditions.
