IGF-BPs controls the distribution, function and activity of IGFs in various cell tissues and body fluids.Currently there are seven named IGF-BPs that form high affinity complexes with both IGF-I and IGF-II.IGF-BP2 is a cysteine-rich secreted protein produced by bone cells, and is most abundant in the brain.IGF-BP2 has been shown to inhibit IGF-II action in human breast and ovarian carcinoma cells.Recombinant human IGF-BP2 is a 31.5kD protein consisting of 289 amino acid residues including the IGF-BP domain and thyroglobulin type-I domain.
Manufactured using (BTI-Tn-5B1-4) cells under license from the Boyce Thompson Institute for Plant Research, Inc.
Catalog #143373
Biological ActivityDetermined by its ability to inhibit IGF-I induced proliferation of FDC-P1 cells.
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.
