HGH 191AA 15IU

The human growth hormone (HGH) peptide fragment known as 191 amino acids (191AA) is a truncated form of the native growth hormone molecule. This research-use-only peptide variant, containing 15 IU of biological activity, is intended for academic, scientific, and pharmaceutical research applications. It serves as a tool to study molecular interactions, receptor binding, and potential therapeutic mechanisms in controlled experimental settings.

Research Context

Growth hormone (GH) is a potent anabolic hormone secreted by the pituitary gland, playing a critical role in growth, metabolism, and cellular repair. The 191AA fragment represents a portion of the native protein, encompassing the biologically active domain that interacts with growth hormone receptors (GHR). This peptide is commonly used in studies investigating receptor binding affinity, signaling pathways, and the structural biology of GH. Due to its research-only designation, this material is not intended for human or veterinary use and should be handled strictly within an approved research framework.

Research Overview

In laboratory research settings, the 191AA peptide fragment serves as a tool for investigating the structural and functional aspects of growth hormone. It is frequently used in assays to study the specificity of GHR binding, ligand-receptor interactions, and the biochemical pathways mediated by GH. The 15 IU measurement denotes the peptide’s theoretical biological activity, measured in units relative to the International Standard for human growth hormone. This peptide is not a clinical or therapeutic agent and is provided exclusively for academic and research purposes.

Key Research Focus Areas

• Growth Hormone Receptor (GHR) Binding Studies: Investigation of ligand-receptor interactions to elucidate binding affinities, conformational states, and structural dynamics.
• Signal Transduction Mechanisms: Analysis of downstream signaling pathways activated by GH binding to GHR, including JAK-STAT, MAPK, and Akt pathways.
• Structural Biology: Use in crystallography, NMR spectroscopy, and computational modeling to study the three-dimensional conformation and stability of GH and its fragments.
• Biochemical Characterization: Evaluation of proteolytic stability, enzymatic cleavage profiles, and peptide fragmentation in various biological matrices.
• Pharmacological and Toxicological Assays: Support for safety evaluations, dose-response studies, and pharmacokinetic profiling in controlled research environments.
