Insulin-Like Growth Factor I; IGF-I; Mechano Growth Factor; MGF; Somatomedin-C; IGF1; IBP1
描述（Description）
The LR3 IGF-I/IGF-1 protein is similar to insulin and has potent growth-promoting activity that exceeds the efficacy of insulin. As a potential physiological regulator, it stimulates glucose transport and glycogen synthesis in osteoblasts even at significantly lower concentrations than insulin. LR3 IGF-I/IGF-1 Protein, Human (83a.a, E51R) is the recombinant human-derived LR3 IGF-I/IGF-1 protein, expressed by E. coli , with tag free. and E51R, , , , mutation. The total length of LR3 IGF-I/IGF-1 Protein, Human (83a.a, E51R) is 70 a.a., with molecular weight of --11.0 kDa.
