To buy Vilon for enzyme activity research, laboratory investigators require a specialized supplier capable of delivering batch-certified, highly pure synthetic dipeptides with documented analytical verification. PX1 Research supplies research-grade Vilon (Lys-Glu) formulated exclusively for in vitro assay systems, structural chromatin evaluation, and cell culture models. Every batch is manufactured in USA-based, GMP-compliant facilities and verified by third-party ISO 17025 accredited laboratories.
When purchasing research compounds to evaluate enzymatic pathways, raw sample integrity is paramount. Impurities or microbial contaminants like lipopolysaccharides (LPS) can obscure enzyme kinetic data or cause non-specific cytotoxicity in cellular assays. PX1 Research ensures every lot of Vilon undergoes reverse-phase high-performance liquid chromatography (RP-HPLC) and electrospray ionization mass spectrometry (ESI-MS) to confirm identity and maintain purity levels exceeding 98%, with detailed documentation accessible in our research library hub.
Vilon is a synthetic short-chain bioregulatory dipeptide composed of L-lysine and L-glutamic acid (H-Lys-Glu-OH). Originally derived from computational and structural analysis of thymic peptide extracts, this low-molecular-weight compound (molecular weight ~275.3 g/mol) is studied for its ability to penetrate nuclear membranes and interact directly with double-stranded DNA.
Researchers interested in purchasing from a reputable research peptide catalog focus on Vilon due to its minimal structural complexity paired with significant biological activity in preclinical models. Its hydrophilic nature makes it highly soluble in aqueous buffer systems, facilitating straightforward integration into standard enzyme assay incubations, gel electrophoresis, and spectroscopic analysis.
Preclinical studies suggest that short peptide sequences like Lys-Glu exhibit sequence-specific binding capabilities within the major and minor grooves of DNA. In vitro assays demonstrate that Vilon can induce site-specific alterations in chromatin conformation, promoting the decondensation of heterochromatin into euchromatin. This structural shift alters the accessibility of promoter regions to endogenous RNA polymerases and chromatin-modifying enzymes.
In vitro data indicate that Vilon influences the enzymatic expression and functional kinetics of key intracellular enzymes, including superoxide dismutase (SOD), catalase, and various histone deacetylases (HDACs). By modulating the activity of enzymes involved in oxidative stress management and epigenetic regulation, Vilon serves as a primary model for investigating peptide-driven genomic regulation without the requirement for large protein transcription factors.
Extensive preclinical literature highlights the role of Vilon in cellular aging and enzyme kinetics. In rodent models and isolated cell cultures, exposure to Vilon has been associated with elevated activity of antioxidant enzymes, resulting in reduced levels of lipid peroxidation products and reactive oxygen species (ROS). Furthermore, research indicates potential regulatory effects on telomerase complex assembly and enzymatic turnover in senescence assays.
Investigative studies employing human fibroblast cultures and murine splenocytes demonstrate that Vilon modulates the activity of enzymes governing immune response cascades, such as protein kinase C (PKC) isoforms. These mechanistic insights make Vilon a compelling target for laboratories studying age-related enzymatic decline, cellular resilience, and nuclear architecture modifications. Detailed summaries of these mechanisms can be found in our technical article on epigenetics and short bioregulatory peptides.
Vilon belongs to a broader class of short synthetic peptide bioregulators initially conceptualized by Professor Vladimir Khavinson. When designing targeted in vitro protocols, researchers often compare Vilon (Lys-Glu) against related short-chain peptides to evaluate structural specificity across different tissue-specific enzyme models.
While Vilon is primarily utilized for thymic and general chromatin decondensation models, Epitalon research peptides (Ala-Glu-Asp-Gly) are specifically studied for pineal gland regulation and direct telomerase activation. Similarly, Thymalin bioregulator research centers on complex multi-peptide thymic extracts, whereas Vilon offers a defined, single-dipeptide model ideal for precise kinetic assays. Selecting the appropriate compound depends on whether the laboratory objective requires a single-target dipeptide like Vilon or a broader tetrapeptide sequence. Researchers can inspect our full inventory through our product selection page.
In enzyme kinetics and transcriptional expression experiments, even microgram-level impurities can act as competitive inhibitors or non-specific activators, yielding compromised data. When choosing a buy Vilon enzyme activity supplier, principal investigators must require comprehensive batch-specific analytical documentation.
PX1 Research mandates strict quality control protocols for every lot. Each synthesis batch undergoes rigorous testing to confirm exact peptide sequence, molecular weight, purity, and freedom from synthesis byproducts such as trifluoroacetate (TFA) salts or uncoupled amino acid residues. Laboratory leaders evaluated through our wholesale lab account portal receive direct access to these batch-specific testing archives prior to procurement.
Every vial of Vilon supplied by PX1 Research is subjected to double-verification testing at an independent, ISO 17025 accredited analytical facility. Purity determination relies on RP-HPLC using C18 stationary phases, ensuring accurate resolution of hydrophobic and hydrophilic impurities with a clear, quantified area-under-the-curve (AUC) profile.
Molecular weight validation is completed using ESI-MS to confirm the exact monoisotopic mass of Lys-Glu. Additionally, because bacterial endotoxins can activate inflammatory pathways in cell culture assays and skew enzyme activity data, PX1 Research measures endotoxin levels via Chromogenic Recombinant Factor C (rFC) or LAL assays, guaranteeing levels well below stringent laboratory thresholds (<0.01 EU/mg). Learn more about our validation protocols in our guide on peptide purity testing standards.
Vilon is supplied as a lyophilized (freeze-dried) powder in sealed glass vials to ensure maximum chemical stability during transit and storage. Upon receipt, lyophilized vials should be stored at -20°C or -80°C in a desiccated environment to prevent moisture absorption and peptide degradation.
For reconstitution in laboratory assays, researchers should utilize sterile, bacteriostatic water or phosphate-buffered saline (PBS, pH 7.4), depending on the requirements of the downstream enzyme assay. Allow the vial to equilibrate to room temperature before adding the solvent, gently swirling the vial without aggressive vortexing to preserve peptide structural integrity. Reconstituted stock solutions should be aliquoted into single-use microcentrifuge tubes and stored at -80°C to minimize freeze-thaw cycles. For exact volumetric calculations, researchers can reference our peptide reconstitution calculator.
PX1 Research distinguishes itself as a premier research compound supplier by maintaining strict control over synthesis, quality assurance, and fulfillment logistics. All peptides are manufactured in state-of-the-art USA facilities operating under GMP-compliant protocols, eliminating the risk of international supply chain disruptions and unverified overseas re-packing.
