Vilon is a synthetic Lys-Glu dipeptide (lysine-glutamic acid, also known as KE), one of the short peptide bioregulators of the Khavinson school (Institute of Bioregulation and Gerontology, St Petersburg). It is cited as one of the shortest peptides with documented biological activity — only two amino acids.
Bioregulators are a class of short peptides studied for tissue-specific regulation of gene expression. Vilon is the thymic/immune representative of this family and is studied mainly for regulation of immune function and in the context of longevity. The same group includes Epithalon (a telomeric/pineal bioregulator) and thymic peptides such as Thymulin.
At Peptology it is supplied as a lyophilised research peptide with purity above 99% (see certificates), with a price in Cyprus and pay on delivery. Exclusively for research purposes; it is not a medicine. See also the related bioregulators Epithalon and Thymulin.
In the Khavinson school literature, Vilon is described as a bioregulator acting at the level of gene expression in immune cells. The three axes below summarise the main directions of study of the dipeptide.
IMMUNE REGULATION
Studied as a thymic/immune bioregulator, linked to the function and maturation of T lymphocytes.
GENE EXPRESSION
Regulation of gene expression through “chromatin decondensation” is described — activation of “silent” genes in aged cells.
GERONTOLOGY
Examined in the context of bioregulation and restoration of functions during ageing.
The hypothesis of the Khavinson school is that very short peptides can enter the cell and the nucleus and bind to specific regions of DNA, influencing which genes are active. During ageing some genes become “silent” through chromatin condensation; according to this concept, bioregulators such as Vilon can “open” such regions and restore their expression — a mechanism studied mainly in immune and thymic cells.
The thymus is the organ where T lymphocytes mature, and it shrinks progressively with age (atrophy), which is linked to a weakening of the immune response. Vilon is studied precisely as a thymic bioregulator — in the context of maintaining immune function during ageing.
The family of short peptide bioregulators was developed in St Petersburg and includes tissue-specific peptides, each directed at a specific organ or system. Below is Vilon's place among them.
VILON (KE)
Thymic/immune bioregulator — Lys-Glu dipeptide.
EPITHALON
Pineal/telomeric bioregulator — AEDG tetrapeptide.
THYMIC PEPTIDES
Thymulin, Thymosin — immune regulation and neuroimmune regulation.
The table compares Vilon with other bioregulators by sequence and research direction. Each is tissue-specific and concerns a different system.
| Vilon | Epithalon | Thymulin | |
|---|---|---|---|
| Sequence | Lys-Glu (KE) | Ala-Glu-Asp-Gly | peptide + Zn |
| Research axis | Immunity / thymus | Telomeres / longevity | Neuroimmune regulation |
| Length | 2 amino acids | 4 amino acids | longer |
| Status | Short cycles | Cycles | Cycles |
The comparison is made by composition and direction, for scientific reference. It is not a claim of comparative efficacy.
Most of the research on Vilon comes from the group of Prof. Khavinson and collaborators. It describes effects on the maturation and function of T lymphocytes, on immune regulation and on ageing markers in animal and cell models, as well as interactions with components of the NF-κB pathway.
Since much of the data comes from a single research group, independent replication is limited. This does not diminish the research value of Vilon, but it requires that efficacy data be interpreted with this reservation — and it is the reason it is offered only for research purposes.

Important: The information below summarises ranges observed among researchers and is not a recommendation for use, medical advice or an application instruction.
For reconstitution we recommend Peptide Matrix Water™ — a stabilising solution for reconstituted research peptides; alternatively, bacteriostatic water.
Standard protocol, applicable to all research peptides in the Peptology catalogue. For the concentration of the solution (mg/mL) per vial, use the peptide reconstitution calculator.
1. SOLVENT
2. RECONSTITUTION
The solvent is added to the wall of the vial, without agitation, then wait 10–15 minutes.
3. CALCULATION
Calculator → concentration in mg/mL
4. STORAGE
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water
| Parameter | Value |
|---|---|
| Form | Lyophilised powder |
| Solvent | Peptide Matrix Water |
| Volume for reconstitution | 1–3 mL — 3 mL maximum (capacity of the standard vial) |
| Storage before reconstitution | Room temperature, protected from direct light (refrigeration is not mandatory) |
| After reconstitution | Up to 60 days at +2 °C to +8 °C with Peptide Matrix Water |
Precision pipette
Calibrated, 100–1000 µL — for accurate measurement of the volume of solvent added to the vial.
70% alcohol pads
Two pads — to disinfect the peptide vial and the solvent vial.
Stabilised solvent for lyophilised peptides. Why this one.
| ✅ Correct | ❌ Wrong |
|---|---|
| Disinfect the stoppers and the work surface with 70% alcohol, work with gloves | Working without disinfection |
| The solvent is added slowly down the wall of the vial | Direct jet onto the powder — foaming and denaturation |
| Light swirling between the palms | Shaking — foam, on which the peptides denature |
| Wait 10–15 minutes at room temperature | Mechanical mixing or heating |
| Visual inspection: clear, without particles | Using a cloudy or coloured solution |
⚠️ Maximum 3 mL of solvent. The standard vial does not allow a larger volume — do not exceed it during reconstitution.
Reconstitution per vial — solvent: Peptide Matrix Water. Concentration after addition (1 mg/mL = 1 µg/µL):
| Vial | + 1 mL | + 2 mL | + 3 mL |
|---|---|---|---|
| 20 mg | 20 mg/mL | 10 mg/mL | 6.67 mg/mL |
👉 For any vial and solvent volume — use the calculator. It calculates the concentration (mg/mL, µg/µL) and the volume per sample (mL, µL).
BEFORE RECONSTITUTION
Room temperature, protected from direct light, in the original packaging. Refrigeration is not mandatory.
AFTER RECONSTITUTION
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water. Discard the remainder after this period.
FREEZING
Not recommended. Freeze/thaw cycles degrade the structure of the peptide.
1. Shaking for “faster dissolution”
Foam = denaturation. Only gentle swirling between the palms.
2. Unsuitable solvent
For the stability of the peptide structure, use only a sterile, purpose-designed solvent — Peptide Matrix Water is recommended.
3. Ignoring slight cloudiness
If it is not completely clear = the sample does not meet the criteria for work.
4. Removing it from the refrigerator “for an hour or two”
Short exposures add up and jeopardise stability.
