Product Details

IGF-1 LR3 (Media Grade) is a synthetic peptide analog of insulin-like growth factor-1 (IGF-1), modified to alter its structural and receptor interaction properties. This modification supports extended stability and enables detailed investigation in controlled research environments.

Within laboratory settings, IGF-1 LR3 is utilized to examine receptor-ligand interactions and intracellular signaling pathways associated with growth factor systems. Its structure allows for consistent evaluation of peptide binding dynamics and signal transduction mechanisms at the molecular level.

This compound is supplied strictly for laboratory research purposes and is not intended for consumption, medical, or diagnostic use.

Mechanism of Action

At the molecular level, IGF-1 LR3 is studied for its interaction with insulin-like growth factor-1 receptors (IGF-1R) and related receptor systems. Upon binding, the receptor-ligand complex initiates intracellular signaling cascades involving pathways such as phosphoinositide 3-kinase (PI3K) and protein kinase B (Akt), as well as mitogen-activated protein kinase (MAPK) signaling.

These signaling pathways are analyzed in vitro to evaluate their role in cellular communication, transcriptional regulation, and protein synthesis processes. Researchers examine how ligand binding influences receptor activation, downstream signaling propagation, and gene expression patterns.

Additionally, IGF-1 LR3 is investigated for its interaction with insulin-like growth factor binding proteins (IGFBPs), which regulate peptide availability and receptor engagement. These studies contribute to a broader understanding of growth factor signaling and molecular regulation under controlled experimental conditions.
