The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-1 is produced primarily by the liver as an endocrine hormone as well as in target tissues in a paracrine\/autocrine fashion. The production of IGF-1 is stimulated by growth hormone (GH) and can be retarded by undernutrition, growth hormone insensitivity, lack of growth hormone receptors, or failures of the downstream signaling pathway post GH receptor including SHP2 and STAT5B. Recombinant human IGF-1 are globular proteins containing 70 amino acids and 3 intra-molecular disulfide bonds. Mature human IGF-1 shares 94 % and 96 % a.a. sequence identity with mouse and rat IGF-1, respectively, and exhibits cross-species activity.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Immunology\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:\u0026gt; 97 % by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSource\u003c\/b\u003e:Escherichia coli.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Recombinant Human Insulin-like Growth Factor-1, 15N Stable Isotope Labeled\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBiological activity\u003c\/b\u003e:Fully biologically active when compared to standard.
