[Cys(Acm)20,31]-EGF (20-31) CAS NO.89991-90-2

[Cys(Acm)20,31]-EGF (20-31) is a stabilized 12-amino acid fragment derived from the mouse Epidermal Growth Factor sequence, encompassing the critical receptor-binding region (residues 20–31). This synthetic peptide features Acetamidomethyl (Acm) protection on both cysteine residues, which prevents unwanted disulfide bond formation and enhances stability for experimental use. It retains key biological properties of the full-length EGF, including mitogenic activity and receptor recognition, making it a valuable tool for studying EGFR signaling pathways in a controlled manner.

1.MECHANISM OF ACTION

The peptide functions as a partial agonist or competitive ligand for the Epidermal Growth Factor Receptor (EGFR). It specifically binds to the extracellular domain of EGFR, mimicking the native EGF interaction, which can lead to receptor dimerization and activation of intrinsic tyrosine kinase activity. This triggers downstream signaling cascades such as MAPK and PI3K/Akt, promoting cellular responses like DNA synthesis and proliferation. The Acm modification on Cys20 and Cys31 allows researchers to study receptor engagement without the complexity of full disulfide bridging, facilitating precise structure-function studies.

2.PRODUCT INDICATIONS

This product is indicated for research use only, specifically in biochemical and cell-based assays investigating EGFR-mediated processes. It is suitable for competitive binding studies, mitogenicity assays, wound healing models, and as a standard in drug discovery screens targeting the EGFR pathway. It is targeted at academic researchers, pharmaceutical R&D scientists, and CROs working on cancer biology, tissue regeneration, and growth factor signaling, providing a cost-effective and stable alternative to full-length EGF for specific experimental applications.

3.CLINICAL EFFICACY OF PRODUCT

As a research-grade biochemical reagent, this peptide is not intended for direct clinical or therapeutic application. Its efficacy is demonstrated in experimental settings, where it serves as a potent tool for elucidating EGFR ligand-receptor dynamics and validating anti-EGFR strategies. In pre-clinical research, it has shown utility in mimicking EGF's proliferative effects in vitro, aiding in the development of targeted therapies and diagnostic agents for EGFR-overexpressing cancers and regenerative medicine approaches.
