Abstract:
Purified compounds comprising truncated insulin-like growth factor binding protein (IGFBP) capable of binding to an antibody specific for the compound or to an insulin-like growth factor wherein the truncated IGFBP has a decreased affinity for insulin-like growth factors (IGFs) are described. Recombinant DNA molecules encoding the truncated IGFBPs are also described along with recombinant microorganisms and cell lines containing the DNA molecules and methods for producing the truncated IGFBPs using recombinant hosts containing the relevant DNA molecules. Methods for stimulating mitogenic activity and also for treating a bone disorder in mammals are also described.
