IGF1 signaling drives cell proliferation, survival, and metabolic regulation, making it a critical target in cancer biology and regenerative research. This tag-free recombinant human IGF-1 encompasses the mature form (residues 52–118) and demonstrates potent mitogenic activity, with an ED50 below 2 ng/mL in serum-free MCF-7 proliferation assays, corresponding to a specific activity exceeding 5.0 × 10⁵ IU/mg — providing reliable, quantifiable dose-response performance for cell proliferation and survival assays, IGF-1R binding and competition studies via ELISA or SPR, and in vivo tumor biology models. Because IGF-1 lacks native glycosylation, E. coli expression yields a correctly folded protein without the batch-to-batch variability that mammalian systems can introduce. Purity above 97% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for serum-free cell culture work and sensitive receptor-ligand interaction experiments.
Applications : Partial correlation analysis
Review: Correlation between IGF-1 and IGFBP-3 in the BC patients serum. The results of partial correlation analysis showed that the levels in serum for IGFBP-3, IGF-1 were positively correlated in BC patients (1=0.970, P<0.001).
