Product Detail

Cortagen is an artificially synthesized polypeptide with the amino acid sequence Ala-Glu-Asp-Pro. Its molecular design is completed according to amino acid component analysis of cortexin extracted from natural cerebral cortex samples.

Related laboratory simulation experiments have observed that this polypeptide substance generates influences on motor indicators within isolated experimental systems, without interfering with emotional-related test indicators of experimental samples. Laboratory research also explores the structural and index variation rules of peripheral nerve tissues as well as cardiovascular and cerebrovascular related indicators under simulated damaged environments after being treated with Cortagen. Meanwhile, experimental observations prove that this compound can cause variations in the expression level of the interleukin-2 gene in mouse splenocyte samples.

By comparing cardiac gene expression profiles triggered by synthetic peptides including Cortagen and Epitalon as well as melatonin peptide, the exclusive biochemical properties of Cortagen in regulating cardiac gene expression can be verified.

This polypeptide raw material is only allowed for laboratory biochemical analysis, molecular mechanism research and cellular control tests. All experimental data are merely for academic reference. This substance shall not be applied to human clinical treatment, skin care, anti-aging, wrinkle elimination and other practical scenarios related to human bodies.
