Recombinant Human IGF-1, Tag Free

Insulin-like growth factor I (IGF-1) is a polypeptide endocrine hormone structurally similar to insulin and is mainly produced in the liver when stimulated by growth hormone. IGF-1 is a growth factor that stimulates the proliferation of various cell types including muscle, bone, and cartilage tissue. IGF-1 binds and interacts with the IGF-1 binding proteins (IGFBPs). IGF-1 binds to the IGF-1 receptor with a higher affinity than the insulin receptor.

Human IGF-I is synthesized as two precursor isoforms with N- and alternate C-terminal propeptides, which are proteolyzed to produce the identical 7.6 kDa mature IGF-I. Mature human IGF I shares 94% and 96% aa sequence identity with mouse IGF1 and rat IGF1, respectively, and exhibits cross species activity. Human IGF-1 is a 7.6 kDa protein containing 70 amino acid residues. The recombinant human IGF-1 was produced using animal origin free technology.
