To buy Vilon from a reliable biological activity supplier, research institutions require analytical-grade material backed by transparent chemical verification. Vilon (Lysyl-Glutamic acid) is a synthetic bioregulatory dipeptide studied for its influence on chromatin structure, gene transcription, and cellular senescence pathways in preclinical models. PX1 Research supplies high-purity Vilon synthesized in GMP-compliant facilities with lot-specific HPLC and MS reports.
In experimental biology, sourcing peptides from a qualified domestic vendor ensures batch-to-batch consistency and eliminates structural ambiguity. Every lot of Vilon provided by PX1 Research undergoes independent laboratory verification, ensuring high chemical purity and sub-threshold endotoxin levels suitable for cell culture assays and molecular screening. Researchers evaluating our expanded catalog can explore our complete all peptides inventory or establish institution-level accounts via our wholesale research portal.
Vilon is a ultra-short synthetic dipeptide composed of L-lysine and L-glutamic acid (H-Lys-Glu-OH). Possessing a molecular weight of approximately 275.3 g/mol, its minimal steric footprint allows it to interact directly with nuclear structures and specific DNA motifs without requiring complex carrier proteins during in vitro administration.
The chemical architecture of Lys-Glu presents both basic (amino) and acidic (carboxyl) side chains, creating a zwitterionic character at physiological pH. This unique electrostatic profile facilitates binding interactions with negatively charged DNA phosphate backbones and histone proteins. Investigators utilizing high-purity Vilon focus on how this simple primary sequence induces specific conformational changes within nuclear chromatin arrays.
Preclinical investigations demonstrate that short bioregulatory peptides like Vilon play a structural role in epigenetic regulation. In vitro fluorescence and circular dichroism spectroscopy studies reveal that Lys-Glu can intercalate into the major and minor grooves of double-stranded DNA, specifically targeting heterochromatin domains.
By interacting with condensed heterochromatin, Vilon induces local structural relaxation or 'chromatin unpacking.' This conformational change exposes previously silenced promoter regions to RNA polymerase complexes, thereby modulating the transcription rate of specific stress-response and structural genes. Researchers studying the broader scope of peptide-driven epigenetic modulation can cross-reference findings in our research library hub.
In cell culture models of primary lymphocytes and thymocytes, Vilon exposure has been associated with altered expression profiles of key immune markers. In vitro assays indicate that Lys-Glu promotes the expression of differentiation markers such as CD3 and CD4, suggesting a regulatory mechanism over T-cell maturation signaling pathways without triggering non-specific inflammatory cascades.
Furthermore, rodent models evaluating age-associated cellular decay have examined Vilon's influence on oxidative stress pathways and telomere homeostasis. Preclinical data suggest that long-term incubation with Lys-Glu dipeptide reduces markers of lipid peroxidation and restores baseline activity of endogenous antioxidant enzymes, such as superoxide dismutase (SOD). These findings position Vilon as a key target in research surrounding cellular longevity and tissue homeostasis.
Vilon belongs to a distinct class of short bioregulatory peptides evaluated for chromatin interaction and tissue-specific signaling. When designing comparative studies, laboratories often contrast Vilon (Lys-Glu) with longer synthetic peptides such as Epitalon (Ala-Glu-Asp-Gly) and other short thymic-derived signaling agents like Thymogen (Glu-Trp).
While Epitalon primarily targets neuroendocrine signaling and telomerase activity in pineal and epithelial assays, Vilon demonstrates a more localized charge-driven affinity for dense heterochromatin regions. Thymogen, by contrast, operates predominantly through specific cell-surface receptor pathways involved in T-cell activation. Evaluating these distinct physical profiles allows investigators to select the exact bioregulatory agent tailored to their experimental endpoints.
When purchasing research compounds online, verifying supplier quality requires reviewing rigorous analytical documentation. PX1 Research mandates that every batch of Vilon undergo dual-stage testing by an accredited ISO 17025 laboratory. High-Performance Liquid Chromatography (RP-HPLC) is performed to establish chemical purity, ensuring freedom from truncated sequence fragments or synthetic byproducts.
Simultaneously, Electrospray Ionization Mass Spectrometry (ESI-MS) confirms the exact molecular mass (275.3 Da) of the Lys-Glu molecule. Detailed information regarding analytical methodology and interpretation can be found in our technical guide on peptide purity HPLC and mass spectrometry standards. Each shipment includes a lot-specific Certificate of Analysis (COA) detailing quantitative purity percentages.
For cell culture models and immunological assays, trace contamination by bacterial endotoxins (lipopolysaccharides, LPS) can invalidate experimental outcomes by stimulating false-positive immune responses. PX1 Research subjects all peptide lots to quantitative Chromogenic Recombinant Factor C or LAL endotoxin assays.
Our stringent manufacturing standards enforce endotoxin limits far below standard industry benchmarks for research-grade reagents. This guarantees that observed biological activity in T-cell or chromatin assays can be attributed strictly to the Vilon compound rather than background microbial pyrogens.
Vilon is supplied as a lyophilized white powder to maximize chemical stability during transport and storage. For laboratory preparation, the peptide should be reconstituted using sterile Bacteriostatic Water or sterile phosphate-buffered saline (PBS, pH 7.4), depending on the specific requirements of the downstream in vitro protocol.
Lyophilized vials should be preserved at -20°C upon receipt, protected from light and moisture. Following reconstitution, aliquots should be prepared to avoid repeated freeze-thaw cycles and stored at -80°C for long-term experimental use. Laboratory personnel seeking detailed liquid handling protocols can consult our comprehensive peptide reconstitution calculator guide.
PX1 Research operates strictly within US-based ISO-certified and GMP-compliant synthesis facilities. By maintaining complete domestic control over synthesis, purification, and packaging, we eliminate cold-chain disruptions and customs delays that often compromise peptide integrity when sourcing overseas.
Orders placed before cut-off times ship same-day from our fulfillment hubs in California and Arizona. Whether procuring individual vials for preliminary assay screens or placing bulk volume requests via our wholesale accounts team, research institutions receive fully documented, stable compounds backed by domestic customer support.
What is Vilon supplied for in laboratory settings?
Vilon (Lys-Glu) is supplied exclusively as a research-grade peptide compound intended for in vitro assays, epigenetic studies, and preclinical rodent models. It is strictly not for human consumption or clinical use.
What is the primary mechanism of action attributed to Vilon in literature?
Preclinical literature indicates that Vilon interacts directly with heterochromatin DNA sequences, inducing local chromatin unpacking and altering the transcription of specific genes related to cell differentiation and oxidative stress response.
How does PX1 Research verify the purity of Vilon?
Every lot of Vilon undergoes independent testing by an ISO 17025 accredited laboratory using Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) for chemical purity and Mass Spectrometry (MS) for molecular weight verification.
What endotoxin controls are applied to PX1 Research Vilon?
PX1 Research subjects every batch to quantitative LAL endotoxin assays, ensuring sub-threshold pyrogen levels to prevent confounding immunological responses during cell culture experiments.
How should lyophilized Vilon be stored upon delivery?
Lyophilized Vilon should be stored at -20°C in a dry, dark environment. Upon reconstitution with sterile buffer or solvent, aliquots should be stored at -80°C to minimize degradation over multiple freeze-thaw cycles.
How does Vilon compare structurally to Epitalon?
Vilon is a short dipeptide composed of Lysine and Glutamic acid (Lys-Glu), whereas Epitalon is a tetrapeptide (Ala-Glu-Asp-Gly). While both modulate chromatin structure in preclinical models, they target distinct downstream gene expression networks.
