HGH 191AA (Somatropin) is a recombinant 191-amino-acid growth hormone (somatropin), one of the compounds studied in growth-hormone-axis research. This listing supplies the 40IU lyophilized vial for laboratory research use. Every batch is tested to at least 98% purity by HPLC with a certificate of analysis (COA), is USA-made and third-party verified. For research use only; not for human or veterinary use or consumption.
Recombinant somatropin is the intact 191-amino-acid growth hormone used in the literature as the baseline growth-hormone reference. In in-vitro and animal-model systems it is used as a tool protein to study growth-hormone-receptor signalling. This describes a research context only.
Recombinant somatropin is a well-characterized reference protein in growth-hormone-axis research; the various secretagogues and analogs are frequently compared against it. All referenced work is preclinical and mechanistic; no human data or outcomes are implied.
Typical research applications include growth-hormone-receptor reference studies. For background, see the HGH 191AA research overview. Browse the full musculoskeletal & growth research range.
