Product Description
HGH 191AA (Somatropin) is a recombinant form of Human Growth Hormone (hGH) consisting of a single-chain polypeptide containing 191 amino acids that is structurally identical to naturally occurring human pituitary growth hormone. It is widely utilized in scientific research involving growth hormone signaling, cellular growth, protein synthesis, metabolism, tissue regeneration, and insulin-like growth factor-1 (IGF-1) pathways. Somatropin exerts its biological activity through binding to growth hormone receptors, stimulating downstream signaling cascades associated with growth and cellular development.
