Insulin-like growth factor-binding protein 3, Insulin Like Growth Factor Binding Protein-3, His Tag, IGFBP3, IBP-3, IGF-binding protein 3, IGFBP-3, IBP3, BP-53, Insulin-like growth factor binding protein 3 isoform b precursor.
IGFBP3 is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein forms a ternary complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor (IGF) I or II. In this form, it circulates in the plasma, prolonging the half-life of IGFs and altering their interaction with cell surface receptors. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.
IGFBP3 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 285 amino acids (28-291a.a.) and having a molecular mass of 31kDa.
IGFBP3 is fused to a 21 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Sterile Filtered clear solution.
IGFBP3 protein solution (1mg/ml) containing 20mM Tris-HCl buffer (pH8.0) and 10% glycerol.
