Vilon is a synthetic Khavinson-type bioregulator tetrapeptide studied in immune and regenerative research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Vilon is investigated for its role in supporting immune-cell function and tissue-regulatory processes, and is commonly applied in cell-based and preclinical studies. As a peptide bioregulator, it does not carry a single unified CAS number. The lyophilized presentation supports convenient reconstitution. The Lys-Glu dipeptide from the bioregulator family is studied for effects on immune-cell function and age-related immune decline. Its minimal structure supports convenient synthesis and dosing. The product is lyophilized with purity documentation. The dipeptide is examined in immune-aging models where its effects on lymphocyte activity are measured against age-matched controls, and its short structure permits straightforward synthesis. Investigators use the lyophilized material with documented purity in both cell-based and in vivo protocols.
