Human IGF1 / IGF-I Protein

Species : Human

Synonyms : IGF-1,IGF-I,IGF1A,IGFI,IGF?I,MGF

Host : E. coli

Purity :> 95 % as determined by SDS-PAGE

Activity : 1.Measured by its binding ability in a functional ELISA. Immobilized Human IGF1(Cat:10598-HNAE) at 2 £gg/ml (100 £gl/well) can bind Human IGFBP4 His(Cat:10967-H08H), the EC50?of Human IGFBP4 His is 10-60 ng/mL.
2. Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. The ED50 for this effect is typically 0.5-2 ng/mL.
3. Measured in a cell proliferation assay using MCF-7 cells. The ED50 for this effect is typically 3.5-14 ng/mL.
