Overview
Ovagen is a synthetic tripeptide with the sequence L-glutamyl-L-aspartyl-L-leucine (Glu-Asp-Leu, or EDL). It comes from the Khavinson programme of short peptide bioregulators, in which tissue-derived peptide preparations were narrowed down to defined two-, three-, and four-residue sequences that could be synthesised reproducibly and characterised analytically.
Structurally, EDL pairs the acidic Glu-Asp motif that runs through much of the series with a hydrophobic C-terminal leucine, making it the tripeptide analogue of Bronchogen's tail chemistry. Our Ovagen is supplied as a 20 mg lyophilized vial, produced by solid-phase peptide synthesis and HPLC purified to a ≥99% specification, with a lot-matched certificate of analysis available. It is sold for laboratory research only.

Working out the concentration
The vial sizes above — 20 mg — describe a mass of material, not a strength. Choose a diluent volume, work it out with the reconstitution calculator, and you have the concentration for your own vial of Ovagen plus the volume that carries any mass you want to withdraw.
If the protocol asks for a molar concentration, the molar concentration calculator converts between 375.38 g/mol, the mass you weigh out and the volume you dissolve it in.
Certificate of analysis
Every lot of Ovagen is released against a certificate of analysis: the batch-specific laboratory data for that lot, not a generic document for the compound. The lot number on the certificate matches the lot number printed on the label you receive — the vial label itself, where the product is vialled — so the record and the material it describes can always be reconciled.
Purity: ≥99% by HPLC — the specification for this listing. The figure for the lot you receive is the one reported on that lot’s certificate.
No lot certificate is on display on this page at the moment. That is a publishing state and not a testing one: lots are released and documented as described above whether or not the document is posted here, and we will send what exists for the lot in stock, or for a lot already on your bench, by its number.
Certificates are available on request before you order as well as after, with no account and no charge. Request the certificate for this listing, read the testing and documentation policy in full, or see how to read a peptide COA.
Questions about Ovagen
What is Ovagen?
Ovagen is the synthetic tripeptide Glu-Asp-Leu (EDL) from the Khavinson short-peptide bioregulator series. It is supplied as a lyophilized powder in a sealed vial with a lot-matched certificate of analysis.
Which tissue is it associated with?
Sources differ. Much of the Russian-language literature discusses EDL in hepatic and protein-synthesis contexts, while other summaries link the name to reproductive tissue. We list the ambiguity openly so researchers check the tissue actually studied in whichever paper they cite.
Is a certificate of analysis available?
Yes. Each lot is HPLC tested against a ≥99% purity specification and a lot-matched COA is available on request, recording the batch identifier, purity result, identity confirmation, and the physical description of the powder.
Why is no CAS number listed?
No widely accepted CAS registry entry is available for this sequence, so the field is left blank rather than populated with an unverified number. Identity rests on the amino acid sequence, molecular formula, and weight confirmed on the lot COA.
How should it be stored?
Store the unopened lyophilized vial at −20 °C, away from light and moisture. Once reconstituted, keep the solution at 2–8 °C for the planned study window, or freeze single-use aliquots to avoid repeated freeze-thaw cycles.
