Buy Vilon Research Peptide

Vilon, also known by its dipeptide designation KE (Lys-Glu), is a synthetic dipeptide bioregulator with the molecular formula C11H21N3O5 and a molecular weight of 275.30 g/mol. Defined by the amino acid sequence Lys-Glu (L-Lysyl-L-Glutamic acid), Vilon is one of the shortest peptides in the Khavinson bioregulator series, a two-residue dipeptide alongside Thymogen (Glu-Trp), and was developed as a synthetic dipeptide analogue derived from thymalin, the calf-thymus polypeptide preparation studied in the same Russian bioregulator programme. Its structure pairs a basic lysine residue with an acidic glutamic acid residue.

Vilon has been investigated in preclinical immunology as an ultra-short peptide bioregulator, with published research characterizing a proposed mechanism of gene-expression modulation through direct DNA interaction rather than cell surface receptor binding. A 2014 Russian-language review proposes a role for the Lys-Glu dipeptide and the tetrapeptide epitalon in regulating the aging-associated genes CCL11 (eotaxin) and HMGB1 (alarmin); the authors themselves present this as a proposed mechanism rather than a measured effect, and describe the direction of the effect inconsistently [1]. In vivo rodent studies have investigated the KE dipeptide in long-term aging protocols, with published research documenting that chronic administration of the Lys-Glu dipeptide inhibited the growth of spontaneous tumors and increased life span in mice, characterizing Vilon as a geroprotective agent across an extended-observation aging protocol [2], making Vilon a key reference compound in peptide bioregulator research examining ultra-short dipeptide modulation of gene expression and gerontological endpoints in preclinical models.

Vilon is produced to research-grade standards and independently verified by third-party HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature controlled, monitored cold storage system. Certificates of Analysis are available to view and download directly on the product page.
