Somatropin 191aa – Research Peptide

Scientific Category: Endocrine Signalling and Growth-Factor Research

Product Information

Overview

HGH Somatropin 191aa is a recombinant peptide corresponding to the full 191–amino-acid sequence of
human growth hormone. It is used as a reference standard in laboratory research examining growth-hormone receptor (GHR) signalling,
protein expression, and cell-regulatory mechanisms. Somatropin 191aa provides a consistent reagent for studies focused
on endocrine communication, receptor interaction, and intracellular pathway mapping.

Potential Research Applications

• Investigation of GH receptor (GHR) binding and JAK–STAT signalling activation
• Assay calibration for growth-factor and receptor studies
• Analysis of protein-expression modulation and cell-signal transduction
• Research on endocrine feedback regulation and molecular growth mechanisms

Scientific Background

Somatropin 191aa is identical in amino-acid composition to the endogenous pituitary growth hormone and
interacts specifically with the GHR receptor to trigger intracellular pathways such as JAK2/STAT5 and MAPK.
These pathways play a central role in regulating gene expression and protein turnover at the cellular level.
In research settings, Somatropin 191aa serves as a controlled model for analysing receptor–ligand interactions,
signal transduction efficiency, and downstream transcriptional responses in growth-factor studies.
The compound is used exclusively in laboratory-based research environments and is not associated with
therapeutic or physiological application.
