Description

Buy 191AA – 10iu Online UK

For laboratories and research institutions investigating cellular signalling pathways, protein synthesis, metabolic regulation, and tissue regeneration, our 191AA 10iu delivers verified ≥98% HPLC purity with comprehensive analytical testing. This recombinant 191-amino acid human growth hormone (somatropin) is identical in sequence to endogenous human growth hormone, providing a molecularly precise tool for GH receptor activation research. Manufactured under stringent controlled conditions, vacuum-sealed in lyophilised form, and preserved through our temperature-monitored cold-chain, every batch is accompanied by a comprehensive Certificate of Analysis. With 100% domestic UK stockholding and same-day dispatch on orders placed before 2:00 PM GMT, we eliminate customs delays that compromise research integrity.

Research Applications & Key Benefits

• GH Receptor Signalling Studies: 191AA provides direct exogenous GH independent of pituitary function, enabling research into GH receptor activation, intracellular signalling cascades, and the molecular mechanisms of growth hormone action. Research models examine receptor binding kinetics, downstream JAK-STAT pathway activation, and GH: GHR complex formation.

• IGF-1 Axis Investigations: As a substrate for hepatic IGF-1 production, 191AA facilitates research into the IGF-1 axis, dose-dependent IGF-1 elevation, and the relationship between GH administration and IGF-1-mediated anabolic signalling .

• Metabolic Pathway Research: Growth hormone affects glucose metabolism, lipid metabolism, and protein synthesis. Research applications include investigation of GH effects on insulin sensitivity, lipolysis via hormone-sensitive lipase activation, lipogenesis regulation, and nitrogen balance studies.

• Protein Synthesis & Cellular Growth Studies: Research models explore GH’s role in stimulating protein synthesis through IGF-1-mediated anabolic signalling, tissue regeneration, and cellular growth pathways. Investigations examine the mechanisms underlying lean mass preservation and metabolic regulation.

• Adipose Tissue & Lipolysis Research: GH promotes lipolysis (fat breakdown) while decreasing lipogenesis in adipose tissue. Research applications include studies examining adipose β2 and β3 receptor regulation, fatty acid oxidation, and the role of GH in adipose tissue metabolism.

• Stability & Protein Chemistry Studies: As a therapeutic protein with well-characterised stability behaviour, 191AA serves as a reference compound in protein chemistry research, including studies examining pH stability, aggregation pathways (interfacial aggregation, temperature sensitivity), deamidation, oxidation, and formulation development.
