LR3 IGF-I, recombinant protein (Media Grade)

(Media Grade), LR3- IGF-I,

Product Specifications Long[R3]IGF-I (Media Grade):

The Product: LR3]  insulin-like growth factor-I (LR3]IGF-I) is an 83 amino acid analog of human IGF-I comprising the complete human IGF-I sequence with the substitution of an Arg (R) for the Glu (E) at position 3 (hence R3), and a 13 amino acid extension peptide at the N-terminus. GroPeo sientists have engineered this analog with the express purpose of increasing iological activity. LR3IGF-I is significantly more potent than IGF-I in vitro and in vivo. The enhanced potency is due to the markedly decreased binding of LR3 IGF-I to all IGF binding proteins.  These binding proteins normally inhibit the biological actions of IGFs.

Source: LR3]IGF-I is produced in E. coli using a patented expression system.
