General description

SILu™Prot IGF-1 is a recombinant, stable 15N isotope-labeled human IGF-1. Expressed in E. coli, it is designed to be used as an internal standard for bioanalysis of IGF-1 in mass-spectrometry. SILu™Prot IGF-1 is a protein of 70 amino acids, with a calculated molecular mass of 7.74 kDa.

Biochem/physiol Actions

Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a protein that in humans is encoded by the IGF1 gene. IGF-1 is a hormone similar in molecular structure to insulin. It plays an important role in childhood growth and continues to have anabolic effects in adults. A synthetic analog of IGF-1, mecasermin, is used for the treatment of growth failure.

Physical form

Supplied as a lyophilized powder containing tris buffered saline and methionine
