To buy Vilon for membrane binding and epigenetic research, investigators require a USA-based supplier providing HPLC- and mass-spectrometry-verified Lys-Glu dipeptide with full lot-specific Certificate of Analysis data. PX1 Research manufactures research-grade Vilon under strict ISO 17025 laboratory quality control compliance, ensuring >98% peptide purity, verified endotoxin thresholds (<0.01 EU/mg), and same-day dispatch from California and Arizona distribution hubs for consistent experimental reproducibility.
Selecting a reliable supplier for small regulatory peptides like Vilon demands rigorous verification of analytical data. Small synthetic dipeptides are particularly sensitive to salt variations, counter-ion retention, and TFA residue. Accessing analytical grade reagents through established high-purity research peptides catalogs ensures that laboratory models evaluating cell membrane dynamics, receptor docking, or nuclear translocation receive stable, unadulterated compounds free from chemical artifacts.
Vilon is a synthetic short-chain dipeptide comprising L-lysine and L-glutamic acid (Lys-Glu). With a molecular formula of C11H21N3O5 and a molecular weight of approximately 275.3 g/mol, Vilon exhibits a distinct zwitterionic profile at physiological pH. The basic amino group of lysine and the acidic side chains of glutamic acid endow the molecule with amphiphilic characteristics that heavily influence its interaction with lipid bilayers and nuclear structures.
In analytical environments, the charge distribution of Lys-Glu facilitates specific non-covalent interactions with negative cell membrane components, such as phosphatidylserine and glycosaminoglycans. Laboratory researchers utilizing our Vilon research peptide leverage these defined chemical attributes to study short peptide permeability, active transport mechanisms, and cellular uptake without the confounding variables introduced by larger protein constructs.
Preclinical literature demonstrates that short bioregulatory peptides undergo specific electrostatic and hydrophobic interactions with cell membranes before exerting intracellular effects. In vitro assays indicate that the Lys-Glu motif of Vilon binds to outer membrane microdomains, influencing membrane fluidity and local charge density. This initial binding event is hypothesized to precede endocytosis or direct translocation across the lipid bilayer into the cytosol.
Once internalised, animal and cell culture models demonstrate that Vilon migrates toward the cell nucleus, where it binds directly to the major and minor grooves of double-stranded DNA. In vitro chromatin unwinding assays indicate that Lys-Glu interacts with histone proteins and specific promoter regions, inducing local chromatin decondensation. This mechanism enhances RNA polymerase accessibility, modulating the transcriptional activation of genes implicated in cellular senescence, ribosomal protein synthesis, and immune cell proliferation.
Detailed examination of these nuclear binding dynamics is available within the expanded PX1 research library, which catalogues mechanistic data on short-chain peptide interactions across cellular and subcellular compartments.
In preclinical studies, Vilon has been extensively evaluated in primary lymphocyte cultures, fibroblast lines, and organotypic tissue slice preparations. In vitro data indicate that exposure to Lys-Glu stimulates the expression of markers associated with T-cell differentiation, including CD3 and CD4 surface antigens. Researchers monitor these surface changes using flow cytometry and immunofluorescence to map membrane receptor kinetics following peptide contact.
Furthermore, rodent models evaluating age-associated cellular decline demonstrate that Vilon administration alters chromatin structure in splenocytes and hepatocytes, reducing markers of oxidative stress and apoptosis. In vitro cell senescence assays reveal that culturing late-passage cells with Vilon maintains telomere integrity and transcriptomic stability, establishing Lys-Glu as an essential control compound in aging and cellular longevity research.
When designing comparative bio-assays, laboratories frequently evaluate Vilon alongside other short-chain peptide bioregulators to isolate sequence-specific binding affinities. While Vilon (Lys-Glu) targets specific chromatin regions related to immune competence, Epitalon (Ala-Glu-Asp-Gly) operates primarily via telomerase activation and pineal gland gene expression models. Similarly, Thymogen binding mechanics (Glu-Trp) demonstrate distinct membrane surface charge interactions optimized for thymic cell signal transduction, while Pinealon (Glu-Asp-Arg) selectively target neuronal tissue expression profiles.
Understanding these structural differences allows investigators to select the precise peptide geometry required for their specific membrane binding or nuclear localization studies. The table below outlines key structural parameters across this compound class:
Ensuring experimental integrity requires verifiable analytical proof for every batch of research peptides. At PX1 Research, every lot of Vilon undergoes independent third-party testing at an ISO 17025 accredited laboratory. Our verification protocol includes Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) to confirm peptide purity exceeds 98.0%, and Electrospray Ionization Mass Spectrometry (ESI-MS) to verify precise molecular weight (275.3 Da).
Additionally, because membrane binding and cell culture assays are extremely sensitive to bacterial pyrogens, our compounds undergo quantitative Chromogenic Reagent Endotoxin Assay testing to guarantee limits stay below 0.01 EU/mg. Complete analytical documentation, including raw chromatograms and mass spectra, is accessible directly through our endotoxin analysis protocols documentation and individual product COAs.
Vilon is supplied as a lyophilized white powder under vacuum or inert argon atmosphere. To preserve molecular stability and prevent premature peptide degradation, laboratories should adhere to standardized storage and handling procedures:
Lyophilized Vilon should be stored at -20°C upon receipt, protected from light and moisture. For long-term preservation exceeding six months, storage at -80°C is recommended. Prior to reconstituting, allow the vial to equilibrate to room temperature inside a desiccator to prevent atmospheric condensation on the cake.
Reconstitution should be performed using sterile Bacteriostatic Water, Sterile Water for Injection (WFI), or phosphate-buffered saline (PBS, pH 7.4) depending on the requirements of your cell culture protocol. Gently swirl the vial until complete dissolution occurs; do not vortex vigorously, as mechanical shear forces can cause aggregation. Reconstituted aliquots should be frozen at -20°C to avoid repeated freeze-thaw cycles, which compromise peptide integrity.
Research institutions, academic universities, and contract research organizations (CROs) require dependable supply chains to maintain uninterrupted longitudinal studies. PX1 Research maintains state-of-the-art storage facilities in California and Arizona, providing fully temperature-controlled inventory management.
Orders placed before 12:00 PM PST Monday through Friday ship same-day via expedited courier services, ensuring minimal time in transit.
