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 22.6kD 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 23.0-30.0kD by SDS-PAGE analysis under non-reducing conditions.
Manufactured using (BTI-Tn-5B1-4) cells under license from the Boyce Thompson Institute for Plant Research, Inc.
Catalog #143377
Biological ActivityDetermined by its ability to inhibit IGF-II induced proliferation of human MCF-7 cells. The expected ED50 for this effect is 0.1-0.4ug/ml.
Quality ControlVerified by N-terminal and Mass Spectrometry analyses (when applicable).
Endotoxin<0.1ng/ug of protein (<1EU/ug).
Protein ContentVerified by UV Spectroscopy and/or SDS-PAGE gel.
Storage and StabilityStore lyophilized products at -20°C. For reconstituted solutions of most products, we recommend short-term storage at 4°C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20°C. Additional freeze/thaw cycles may cause some denaturation of the protein.
