Active Recombinant Human IGF2 Protein (Ala25-Glu91), N-His tagged, Animal-free, Carrier-free

• Cat.No.: IGF2-159H
• Product Overview: Recombinant Human IGF2 Protein (Ala25-Glu91) with N-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Insulin like Growth Factors 2 (IGF-II) is a 7.48 kDa member of the Insulin-like Growth Factors with 67 amino acid residues. IGF-II is mainly expressed from placenta, extravillous trophoblasts, leydig cells, syncytiotrophoblasts, cytotrophoblasts, peritubular cells. IGF-II regulating fetoplacental development and tissue differentiation. In adults, IGF-II signaling involves glucose metabolism in adipose tissue, skeletal muscle and liver. It also has important implications for metabolic disorders and cancer.
