Vilon (Bioregulator) from Xcel Peptides

Xcel Peptides supplies Vilon as a lyophilized bioregulator peptide for laboratory use. We test every batch independently before release, and we publish the certificate of analysis on this page, matched to the batch number on your vial.

What Is Vilon

Vilon is a synthetic dipeptide made of two amino acids: lysine and glutamic acid (Lys-Glu, or KE). Its molecular weight is about 275.3 g/mol. Vladimir Khavinson and colleagues in Russia developed it within their short-peptide bioregulator program, based on peptide fractions associated with thymus tissue. At only two amino acids, Vilon is among the shortest peptides studied in this field.

Specifications

The product is a lyophilized powder at research grade. We verify every batch through third-party HPLC and identity analysis, and we document it with a matched COA. Store the powder frozen and protect it from light. We ship every order cold-chain with tracking.

Research Applications

Researchers study Vilon in immune cell biology and gene expression research. Typical work examines how the KE sequence interacts with DNA and chromatin-associated proteins in cell-based models, and how it influences gene expression in cultured lymphoid and other cells. Scientists also use it as a reference peptide when comparing Khavinson-class bioregulators of different lengths.

These describe research applications, not therapeutic claims. The FDA has not evaluated this product, and researchers should not use it to diagnose, treat, cure, or prevent any condition.

Why Buy Vilon From Xcel Peptides

Very short peptides are easy to mislabel, and a dipeptide batch with poor quality control can contain unexpected residues. Xcel Peptides lists the exact sequence for Vilon and tests each batch to confirm identity, so your records match the material you receive.

We also publish our results openly. You can match the batch number on your vial to the COA before you start work, instead of relying on a generic purity claim.

Storage and Handling

Store the lyophilized vial frozen and protected from light before reconstitution. Once reconstituted, refrigerate the solution and use it within a short window, since peptide stability drops considerably outside the dry state. Avoid repeated freeze-thaw cycles, since each cycle degrades the peptide structure further.

Verifying Your COA

Check three things on the COA before you use this product. First, confirm the batch number matches your vial. Second, confirm the test date is recent. Third, confirm the HPLC purity and the identity result match the Lys-Glu sequence for your size. If you need archived data for a previous lot, contact our team and we’ll pull it for you.

Frequently Asked Questions

What is Vilon? It’s a synthetic dipeptide (Lys-Glu) from the Khavinson family of short-peptide bioregulators. Xcel Peptides supplies it as a research-grade lyophilized peptide.

Why is Vilon so short? Khavinson’s group studied peptides of two to four amino acids, based on the idea that very short sequences can interact directly with DNA. Vilon is the shortest member of the group.

What is a bioregulator peptide? It’s a short peptide, usually two to four amino acids, designed to match a fraction isolated from a specific tissue. Researchers study how these peptides affect gene expression in cell models.

Does Vilon come with a COA? Yes. Xcel Peptides ships every vial with a batch-matched certificate of analysis confirming identity and purity.

How should I store Vilon? Store the lyophilized powder frozen and protected from light. After reconstitution, refrigerate the solution and avoid repeated freeze-thaw cycles.

How fast does Xcel Peptides ship this product? We ship most orders within 1 to 2 business days, with cold-chain packaging and tracking included.
