Description
Livagen is a short synthetic peptide used in liver and chromatin research. Limitless Life Nootropics offers it as a 20mg lyophilized vial, made in the USA and independently tested.
What Is Livagen?
The compound belongs to the family of short regulatory peptides developed by Professor Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology. Khavinson’s group proposed that di-, tri- and tetrapeptides isolated from specific organs can penetrate cells, interact with DNA and influence gene expression in a tissue-specific way.
This peptide has the sequence Lys-Glu-Asp-Ala (KEDA) and is associated with liver tissue. Studies have examined its effects on hepatocyte cultures and on chromatin in lymphocytes from older individuals, where it was reported to activate previously condensed regions of chromatin.
Each Premium lyophilized vial contains 20mg and may include trehalose as a lyoprotectant.
Research Applications
Published preclinical work has examined this peptide across several areas of investigation:
- Hepatocyte culture models
- Chromatin activation in aging cells
- Liver enzyme and metabolic gene expression
- Epigenetic regulation research
- Comparisons with other Khavinson peptides
Researchers can review peer-reviewed studies on Khavinson peptides through the National Library of Medicine (PubMed) database.
