Ovagen (Glu-Asp-Leu, EDL) is a short synthetic peptide from the family of peptide bioregulators developed by V. Khavinson and colleagues, each modelled on peptide extracts from a particular tissue — for Ovagen, liver and gastrointestinal tissue.
Ovagen pairs the Glu-Asp motif with a C-terminal leucine and is studied in hepatocyte gene-expression research.

Short Peptide Bioregulators
Khavinson’s group proposed that di-, tri- and tetrapeptides derived from tissue extracts can enter cells and interact with DNA and histone proteins, influencing chromatin structure and tissue-specific gene expression. These peptides are studied mainly in cell-culture and molecular-modelling research. Read the peptide bioregulators overview.
Ovagen and the Glu-Asp (ED) family
Many bioregulators share short sequence cores. Ovagen belongs to the Glu-Asp (ED) family:
| Peptide | Sequence | Tissue of origin |
|---|---|---|
| Ovagen | Glu-Asp-Leu | liver and gastrointestinal tissue |
| Pinealon | Glu-Asp-Arg | brain |
| Crystagen | Glu-Asp-Pro | immune tissue |
| Chonluten | Glu-Asp-Gly | bronchial mucosa |

Purity Testing and Storage
Every lot of Ovagen supplied by Cleared Peptides is tested by an independent laboratory for identity and purity (or composition, for multi-component preparations), and the lot Certificate of Analysis is published on our COA page. Store lyophilized Ovagen at −20 °C, sealed, dry and protected from light. Allow the vial to reach room temperature before opening. Handle according to your institution’s chemical-hygiene procedures.
