About Livagen

Livagen is a synthetic tetrapeptide bioregulator with the sequence Lys-Glu-Asp-Ala (KEDA), developed within the Khavinson class of short peptide bioregulators associated with the St. Petersburg Institute of Bioregulation and Gerontology. It is studied for its reported influence on chromatin structure and tissue-specific gene expression, particularly in liver-associated and lymphocyte models. Puritide Research supplies Livagen as a high-purity, research-use-only material, synthesized for in vitro and animal-model work and backed by third-party-verified certificates of analysis.

What Is Livagen?

Livagen is a short synthetic tetrapeptide composed of lysine, glutamic acid, aspartic acid, and alanine (Lys-Glu-Asp-Ala, or KEDA in single-letter code). It belongs to the family of peptide bioregulators developed by Vladimir Khavinson and colleagues, a body of work centered on short peptides proposed to modulate tissue-specific gene expression.

The central hypothesis in the bioregulator literature is that peptides of two to four residues are small enough to enter cells and nuclei and interact with DNA, particularly in promoter regions, influencing chromatin structure and transcriptional accessibility. Livagen is studied in this framework as a liver-associated bioregulator.

Present understanding derives largely from in vitro assays and animal studies, much of it originating from the St. Petersburg group with limited independent Western replication. Findings should be interpreted within their experimental context and not treated as established clinical outcomes. Puritide Research supplies Livagen strictly for laboratory use; it is not approved for human or veterinary application.
