Insulin-like growth factors (IGF) I and II are peptide hormones that regulate cellular proliferation and differentiation.  Most circulating IGFs exist in 130-150 kDa ternary complexes containing IGF-Binding Protein-3 (IGFBP-3) and an 85 kDa glycoprotein, the acid-labile subunit (ALS).  IGFBP-3 is one of six IGFBPs that, by binding IGF peptides, prolong their half life and maintain the IGF reservoir.  IGFBP-3 is found in body fluids as multiple 40-50 kDa forms as a result of differential glycosylation.  The expression of IGFBP-3 in many tissues suggests that it locally modulates the autocrine/paracrine action of IGF peptides.  IGFBP-3 binding to fibrinogen may be important for wound healing, since this concentrates IGF-I at wound sites and lowers the affinity of IGF-I for IGFBP-3.  In addition, retinoic acid-induced IGFBP-3 expression inhibits the growth promoting effects of IGF-I in breast cancer cells.  This may link the retinoid and IGF systems in cell growth regulation and explain how the loss of retinoic acid receptor β leads to breast cancer progression.  Thus, IGFBP-3 maintenance and regulation of IGF activity in various tissues may have diverse physiological roles.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
