Recombinant insulin-like growth factor

CAS: 67763-96-6

Product name: Recombinant human Insulin-like growth factor-1 (IGF-1)

-Product Introduction

Insulin-like growth factor-1 (IGF-1), also Known as SomatamedinC, belongs to the insulin-like growth factor family and has Structural homology with proinsulin. IGF-1 is a kind of polypeptide that Promotes mitosis. It stimulates the proliferation and survival of muscle, bone, Cartilage and other cells in vitro. IGF-1 can combine with IGF-1R, IGF-2R and Insulin receptor, awaken multiple signal pathways, and participate in cell Proliferation, differentiation, survival, growth, apoptosis and regeneration. Recombinant human insulin-like growth factor (IGF-1), composed of 70 amino Acids, is a bioactive protein for cell culture. this strain was expressed by Recombinant yeast, purified by multi-step separation, and then 0.22 μ M The Lyophilized powder is made by freeze-drying after filtration and bacteria Removal.
