Vilon is a synthetic ultrashort bioregulatory dipeptide consisting of L-lysine and L-glutamic acid (Lys-Glu). Hydrophilic in nature, this low-molecular-weight compound (C11H21N3O5, MW ~275.3 g/mol) was originally identified through structural analysis of thymus-derived peptide extracts. Its short sequence allows for rapid diffusion across biological membranes in cell culture systems without requiring complex carrier proteins.
When investigators order Vilon for laboratory use, understanding its chemical architecture is essential. The basic side chain of the lysine residue paired with the acidic side chain of glutamic acid confers a unique zwitterionic character at physiological pH. This specific ionic distribution facilitates high-affinity interaction with negatively charged DNA structures and nuclear histones, a primary focus of modern epigenetic research.
Preclinical investigation into Vilon centers largely on its capacity to influence nuclear chromatin organization. In vitro assays using cultured human lymphocytes and animal thymocytes demonstrate that Lys-Glu induces structural modification of condensed heterochromatin into transcriptionally active euchromatin. This process of chromatin decondensation exposes previously silent gene loci to RNA polymerase complexes.
Laboratory studies indicate that Vilon binds directly to specific histone motifs and DNA sequences, promoting the expression of ribosomal RNA (rRNA) genes and modulating key markers of cellular aging. By altering chromatin packing density, the dipeptide provides investigators with a model system to explore transcriptional reactivation in senescent T-cell populations. Detailed mechanistic frameworks can be reviewed across our peptide research library.
Thymic involution—the progressive atrophy of the thymus gland with age—is a hallmark of immunosenescence. In animal models, including aging rodents, administration of Vilon has been evaluated for its capacity to restore functional parameters within the immune compartment. Preclinical trials report enhanced proliferation rates of primary thymocytes, elevated expression of differentiation markers, and altered cytokine secretion profiles following exposure to Lys-Glu.
Furthermore, rodent studies examining long-term survival metrics have noted reduced spontaneous tumor incidence and normalized neutrophil-to-lymphocyte ratios in treated cohorts compared to age-matched controls. These findings make Vilon a significant subject of study in experimental gerontology and mucosal immunity research. Scholars analyzing bioregulatory networks frequently pair Vilon data with findings from Epitalon research studies to evaluate dual-organ bioregulation.
Understanding how Vilon fits within the landscape of peptide bioregulators requires comparing its molecular scale and target mechanisms against larger immunomodulatory peptides. While full-length thymic fractions present complex secondary structures, short dipeptides like Vilon focus target interactions down to basic gene expression machinery.
In experimental models, Vilon (Lys-Glu) is frequently evaluated alongside larger short-chain peptides such as Epitalon, which regulates pineal chromatin, and Thymosin Alpha-1, a 28-amino-acid peptide that targets T-cell differentiation pathways directly via Toll-like receptor signaling. While Thymosin Alpha-1 modulates extracellular receptor cascades, Vilon primarily functions via nuclear entry and direct chromatin interaction. Researchers exploring our complete catalog of research peptides often compare these distinct mechanisms when designing multi-target in vitro assays.
Quantitative reproducibility in cellular biology requires absolute chemical purity. Impurities in synthetic peptides—such as truncated sequences, residual coupling reagents, or organic solvents—can produce false positives in sensitive lymphocyte activation assays. PX1 Research subjects every batch of Vilon to rigorous analytical testing in ISO 17025 accredited facilities.
Purity is quantified using Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC), ensuring a baseline purity exceeding 98%. Chemical identity is confirmed through Electrospray Ionization Mass Spectrometry (ESI-MS), matching observed mass-to-charge ratios against theoretical values. Every product shipment includes a batch-specific Certificate of Analysis (COA) detailing these spectra, offering complete traceability for laboratory audits.
Bacterial endotoxins (lipopolysaccharides, LPS) represent a major confounding variable in immunological and thymocyte research. Microgram quantities of contaminating endotoxin can trigger unwanted Toll-like receptor activation, mask real experimental outcomes, or induce premature apoptosis in cultured primary T-cells.
PX1 Research ensures that all Vilon lots undergo stringent Limulus Amebocyte Lysate (LAL) testing to confirm endotoxin levels fall well below standard cell culture thresholds (<0.05 EU/mg). Manufactured under GMP-compliant protocols in USA-based facilities, our raw materials undergo strict bioburden control, providing researchers with reagents suitable for delicate primary cell cultures and live-animal imaging studies.
Vilon is supplied as a lyophilized (freeze-dried) sterile powder to ensure maximum chemical stability during storage and transit. For laboratory applications, proper reconstitution protocols must be observed to maintain peptide integrity:
1. Centrifuge the vial briefly at low speed prior to opening to consolidate lyophilized powder at the bottom of the vessel. 2. Reconstitute using sterile, endotoxin-free Bacteriostatic Water, Phosphate-Buffered Saline (PBS, pH 7.4), or Sterile Water for Injection, depending on the requirements of the downstream assay. 3. Gently swirl or invert the vial until complete dissolution is achieved; avoid violent vortexing to prevent mechanical shear stress. 4. Work under a laminar flow biosafety cabinet to prevent biological contamination.
To prevent hydrolytic degradation and deamidation, lyophylized Vilon should be stored at -20°C upon receipt for short-to-medium duration research, or at -80°C for long-term preservation. Under sub-zero conditions, lyophilized Vilon maintains stability for up to 24 months without significant degradation.
Once reconstituted into aqueous solutions, working aliquots should be prepared immediately to avoid repeated freeze-thaw cycles, which degrade peptide bonds. Reconstituted liquid aliquots remain stable at 4°C for up to 7 to 14 days, or at -20°C for up to 3 months. All shipments from PX1 Research utilize protective packaging dispatched from West Coast and Southwest hubs to prevent thermal denaturation during transit.
