Recombinant 22 kDa human Growth Hormone (somatropin) expressed in E. coli. WHO IU potency assigned. Standard research reagent for GH receptor signaling and IGF-1 axis studies.
Recombinant Human Growth Hormone (rhGH, somatropin) is a 191-amino acid 22 kDa single-chain protein produced in E. coli and refolded to match the native 22 kDa pituitary isoform. It acts through the GH receptor (GHR) via JAK2/STAT5b signaling to stimulate hepatic IGF-1 production and exerts direct anabolic, lipolytic, and diabetogenic effects in multiple target tissues.
Expression: E. coli; Purity >=99% by SDS-PAGE; RP-HPLC >=99%; bioactivity confirmed vs. WHO IS; endotoxin <=1 EU/mg. Full CoA provided.
