Cat no: I7661-11A

Insulin-Like Growth Factor I, Recombinant, Human (IGF1, IGF I)

IGF-I (E3R) (insulin-like growth factor I) is a 70 amino acid analog of human IGF-I with the substitution of an Arg for Glu at position 3. IGF-I (E3R) is significantly more potent than IGF-I in vitro and in vivo because IGF-I (E3R) has decreased binding to all IGF binding proteins. \n\nBiological Activity: \nStimulation of protein synthesis in L6 myoblasts: ED50 = 19.9ng/ml. \n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Reconstitute to nominal volume by adding 100mM acetic acid or 10mM HCL. Aliquot and store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. .
