Vilon is a two-amino-acid peptide — lysine joined to glutamic acid, written Lys-Glu or KE — with free amino and carboxyl ends. No compound in the Khavinson bioregulator range is smaller, and it is where the whole class began: while working with peptide extracts from the thymus, researchers at the Institute of Bioregulation and Gerontology in St Petersburg identified the shortest active sequence and then made it synthetically — a molecule that can be produced identically every time and characterised with precision.
With just two residues, Vilon is the natural benchmark for structural research on ultrashort peptides. Its size makes it ideal for modelling how peptides might recognise DNA, and for testing the minimum amount of sequence a peptide needs before it behaves selectively in a biological assay. Studies along these lines report that it changes how tightly chromatin is packed in cultured lymphocytes and alters the expression of a small number of immune genes.
In the lab it is mostly used in immune-cell models, thymus tissue preparations and long rodent studies of ageing that follow survival, cancer rates and immune markers. Vilon is supplied in a 20 mg lyophilised vial, made by SPPS, purified by HPLC against a ≥99% specification and accompanied by the certificate for its lot.

Questions about Vilon
What is Vilon?
The synthetic dipeptide KE (Lys-Glu) — the smallest member of Khavinson's short-peptide bioregulator family — delivered as lyophilised powder in a sealed vial with a certificate for its lot.
Do you provide a certificate of analysis?
Yes, before or after you buy. HPLC testing against a ≥99% purity specification is done on every lot, and the certificate lists the batch code, the purity measured, the identity check and what the powder looks like.
Why does Vilon have only two amino acids?
It came from searching thymus peptide extracts for the tiniest fragment that still worked. Cutting the extract down to one defined dipeptide gave scientists a molecule that can be made exactly the same way every batch and analysed with ordinary methods.
How is Vilon stored and shipped?
We send vials from our EU warehouse in protective packaging. Keep the dry powder frozen at −20 °C, protected from light and damp; after reconstitution, refrigerate it at 2–8 °C for the whole of the planned study.
Which sizes can I order?
One size: a 20 mg lyophilised vial — the standard research amount throughout this bioregulator series, which makes comparing peptides from the same family straightforward.
