Every batch undergoes rigorous RP-HPLC and ESI-MS testing, ensuring >98% purity and low endotoxin levels for dependable in vitro and preclinical research applications.
Vilon is a synthetic short dipeptide composed of L-lysine and L-glutamic acid (Lys-Glu). Originally identified during investigation of thymic peptide fraction extracts, Vilon has gained significant attention in experimental radiobiology and cellular genetics. Researchers investigating ionizing radiation recovery utilize Vilon to examine its interactions with nuclear histone proteins, epigenetics, and chromatin structure in cell cultures and animal tissue models.
As an established supplier of research peptides, PX1 Research provides institutional accounts and independent laboratories with fully documented compounds, complete with public COA data, same-day domestic shipping from California and Arizona facilities, and strict quality control standards.
Vilon has the chemical formula C11H21N3O5 and a molecular weight of 275.30 g/mol. Despite its structural simplicity as a dipeptide, preclinical data indicate that Lys-Glu possesses high biological activity at the genomic level. Small peptide chains can traverse cellular and nuclear membranes without requiring active receptor-mediated endocytosis, allowing direct interaction with nuclear chromatin.
In vitro assays demonstrate that Vilon binds directly to specific peptide-binding motifs within the major and minor grooves of double-stranded DNA, as well as histone proteins (specifically H1 and H3). By modulating histone-DNA electrostatic interactions, Vilon induces local chromatin decondensation (euchromatin formation). This structural uncoiling increases the accessibility of promoter regions to RNA polymerase II and specific transcription factors.
For investigators evaluating cellular repair cascades following oxidative or radiological insult, understanding this chromatin-modulating mechanism is essential. Accessing comprehensive research data on nuclear peptide transport via our peptide research portal provides deeper context on how short chain peptides like Vilon 20mg alter baseline gene transcription in experimental models.
Ionizing radiation induces cellular damage primarily through the generation of reactive oxygen species (ROS) and direct physical disruption of phosphodiester backbones, resulting in single-strand and double-strand DNA breaks (DSBs). Preclinical studies suggest that pre- or post-treatment of cultured mammalian cells with Vilon attenuates radiation-induced apoptosis and accelerates structural DNA repair kinetics.
In vitro radiation exposure models using human peripheral blood lymphocytes and fibroblast cultures have demonstrated that administration of Lys-Glu reduces the frequency of chromosomal aberrations and micronuclei formation following gamma or X-ray irradiation. Researchers quantify these effects by measuring changes in phosphorylated histone H2AX (γ-H2AX) foci, a key molecular marker for double-strand break repair.
Furthermore, rodent models evaluating systemic gamma-irradiation exposure indicate that Vilon administration supports hematopoietic cell regeneration, accelerates spleen colony formation, and maintains integrity in intestinal epithelial crypt cells. These findings indicate that Vilon-induced chromatin accessibility may upregulate endogenous antioxidant enzymes—such as superoxide dismutase (SOD) and glutathione peroxidase (GPx)—while simultaneously facilitating DNA repair enzyme recruiting mechanisms.
To contextualize Vilon within the broader landscape of cytoprotective and bioregulatory peptide compounds, researchers frequently compare its structure, target pathways, and experimental parameters against other synthetic short-chain peptides.
When designing radioprotective or tissue-repair experimental protocols, scientists evaluate Epitalon (a tetrapeptide targeting telomerase activity and pineal regulation), Thymogen (a synthetic dipeptide Glu-Trp focused on T-cell differentiation pathways), and BPC-157 (a pentadecapeptide evaluated for angiogenic and soft tissue healing pathways). While Epitalon primarily modulates telomere elongation and circadian gene expression, Vilon acts directly on chromatin structure and immediate-early stress response gene expression. Thymogen shares structural similarities as a dipeptide, yet targets distinct cell-surface receptors within immune lineages, whereas Vilon demonstrates broad intracellular cytoprotection across epithelial, endothelial, and hematopoietic cell lines exposed to radiological stressors.
Evaluating a supplier for laboratory-grade Vilon requires rigorous evaluation of analytical verification protocols. Research results can be corrupted by batch variance, residual organic solvents, TFA (trifluoroacetic acid) contamination, or bacterial endotoxins.
PX1 Research enforces strict quality assurance protocols for every lot of Vilon manufactured:
1. Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC): Establishes chemical purity, ensuring every lot exceeds 98% purity with quantified area-under-the-curve (AUC) reports. 2. Electrospray Ionization Mass Spectrometry (ESI-MS): Confirms exact molecular mass (275.30 Da) and structural identity, eliminating risk of mismatched amino acid sequences. 3. Endotoxin Testing (LAL Assay): Verifies endotoxin levels remain below strictly monitored limits (<0.01 EU/mg), essential for preventing non-specific inflammatory signaling in cell culture or animal assays. 4. Lot-Specific Transparency: Certificate of Analysis (COA) documents from an independent, ISO 17025 accredited laboratory are publicly accessible for every single batch prior to acquisition.
Vilon is supplied as a lyophilized (freeze-dried) sterile powder in sealed glass vials. To preserve peptide integrity and prevent premature enzymatic or hydrolytic degradation, strict laboratory handling procedures must be observed.
Lyophilized Vilon should be stored in a freezer at -20°C or -80°C upon arrival, protected from light and moisture. Prior to reconstitution, vials should be allowed to equilibrate to room temperature inside a desiccator chamber to prevent condensation from accumulating on the cake.
Reconstitution should be performed inside a laminar flow biosafety cabinet using sterile, ultra-pure laboratory grade solvents such as Bacteriostatic Water or Phosphate-Buffered Saline (PBS, pH 7.4). Lys-Glu exhibits high aqueous solubility due to its polar carboxyl and amino side chains. Once reconstituted, solution aliquots should be prepared immediately to avoid repeated freeze-thaw cycles, which can induce physical peptide degradation. Reconstituted aqueous solutions remain stable at 2°C to 8°C for up to 30 days, or at -20°C for up to 6 months. Review our comprehensive peptide reconstitution guide for detailed mathematical dilution tables and solvent compatibility charts.
In cell culture assays evaluating radiation protection, Vilon is typically dissolved in physiological culture media and added to cell cultures (e.g., human dermal fibroblasts, CHO cells, or primary lymphocytes) at concentrations ranging from 0.01 to 10.0 µg/mL. Pre-incubation periods generally range from 1 to 24 hours prior to acute exposure to gamma radiation, X-rays, or ultraviolet radiation.
Experimental endpoints assessed in these models include post-irradiation cell viability (MTT/CCK-8 assays), DNA damage quantification via single-cell gel electrophoresis (Comet assay), and real-time quantitative PCR (RT-qPCR) analyzing heat shock protein (HSP) and antioxidant gene activation profiles.
In vivo rodent models investigating radiation recovery measure parameters such as peripheral blood cell counts, bone marrow cellularity, gastrointestinal villus height, and oxidative stress biomarkers in liver and kidney homogenates post-irradiation.
