Scientific research has examined age-associated variations in IGF-1 signaling and their correlation with cellular growth, tissue remodeling, and metabolic regulation across experimental models.
IGF1 LR3 (insulin-like growth factor-1 Long R3) is a non-glycosylated, recombinant polypeptide chain made up of 83 amino acids. IGF1 LR3 is the recombinant form of human IGF-1, and as such it contains the entire native amino acid sequence but with two major modifications: substitution of arginine (abbreviated R or arg) at position 3 with glutamic acid (abbreviated E or Glu) hence the label _R3_; and the extension of the N-terminus of th
## What is IGF-1? Insulin-like Growth Factor-1 (IGF-1), also known as Somatomedin-C, is a polypeptide growth factor that is a member of the insulin family of peptides. IGF-1 includes 70 amino acids with a molecular weight of 7649 Daltons. Similar to insulin, which has 51 amino acids, IGF-1 has an A and B chain connected by 3 disulfide bonds in a single chain. The main source of IGF-1 for adults is the liver. The Insulin-like growth factors (IGFs)
