Description
Recombinant Human Insulin-like Growth Factor 1 (IGF-1) is a small peptide growth factor that plays a critical role in cell proliferation, differentiation, and survival. It is widely involved in growth and development processes and mediates many of the biological effects of growth hormone. IGF-1 binds to the IGF-1 receptor (IGF1R), activating downstream signaling pathways such as PI3K/AKT and MAPK, which regulate cell growth and metabolism. This recombinant IGF-1 protein is expressed in CHO cells and corresponds to the active human IGF-1 sequence, ensuring proper folding and biological functionality. With high purity (≥95%) and strong bioactivity (ED50 ≤1.5 ng/mL in MCF-7 cell proliferation assay), this product is ideal for research in oncology, cell biology, and metabolic regulation. The protein is supplied in a tag-free, lyophilized form for convenient storage and reconstitution.
