Di-biotinyl human insulin-like growth factor-II (di-biotinyl human IGF-II) is made by reacting human IGF-II (receptor grade) with Sulfo-NHS-Biotin reagent. The α-amino group of the N-terminal alanine and the α-amino group of the lysine at position 65 are biotinylated. Di-biotinyl human IGF-II is separated from the other reaction products and purified by HPLC to yield a receptor grade product.
