Qualified research institutions seeking a reliable Vilon receptor binding supplier must prioritize analytical transparency, lot-to-lot consistency, and complete chemical characterization. Vilon (L-lysyl-L-glutamic acid) is a synthetic short-chain bioregulatory dipeptide evaluated primarily for its interactions with nuclear chromatin structures, histone proteins, and immunological signaling pathways.
PX1 Research provides laboratory-grade Vilon research peptide synthesized in domestic, GMP-compliant facilities. Every batch undergoes rigorous third-party testing via Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) and Mass Spectrometry (MS) to confirm sequence identity and structural purity exceeding 98%. Detailed certificates of analysis (COAs) and endotoxin quantification reports accompany every order to ensure baseline control in rigorous experimental environments.
Vilon is a low-molecular-weight dipeptide consisting of the amino acid sequence Lys-Glu (L-lysyl-L-glutamic acid). With a molecular formula of C11H21N3O5 and a molecular weight of approximately 275.3 g/mol, its short peptide backbone allows for unique transport kinetics and nuclear penetration characteristics during cellular assays.
Because of its hydrophilic nature and dual ionic side chains—containing a positively charged lysine epsilon-amino group and a negatively charged glutamic acid carboxyl group—Vilon exhibits high solubility in aqueous buffer systems such as phosphate-buffered saline (PBS) and sterile water for injection. Research teams utilizing bioregulator research peptides examine how these functional groups participate in hydrogen bonding and electrostatic interactions with targeted DNA sequences and chromatin proteins.
Unlike classical peptide hormones that interact exclusively with cell-surface G-protein coupled receptors (GPCRs) or receptor tyrosine kinases, preclinical literature demonstrates that Vilon exerts direct effects on intracellular and nuclear architecture. In vitro assays reveal that the Lys-Glu motif penetrates cellular membranes to bind specific regulatory regions of chromatin.
Spectroscopic and fluorometric studies indicate that Vilon binds directly to the major and minor grooves of double-stranded DNA, as well as decondensed chromatin. Preclinical data suggest that this binding destabilizes specific histone-DNA complexes, promoting chromatin unpacking and enhancing the accessibility of promoter regions to RNA polymerase. Researchers studying genome activation pathways consult the PX1 Research library hub to evaluate documented nuclear target profiles for short-chain bioregulators.
In vitro and animal models have systematically examined Vilon for its capability to modulate immune system markers and delay markers of cellular aging. In rodent models of immunodeficiency, administration of Lys-Glu resulted in restored thymocyte differentiation, elevated interleukin-2 (IL-2) secretion, and modulated T-cell subpopulation balances.
Furthermore, tissue culture experiments involving senescent human fibroblast lines demonstrate that Vilon exposure correlates with altered gene expression profiles associated with antioxidant defense enzymes, such as superoxide dismutase (SOD) and catalase. These preclinical observations indicate that Vilon may serve as a potent tool for investigating chromatin remodeling, epigenetic reactivation, and thymic involution in controlled laboratory environments.
To contextualize Vilon within the broader class of short-chain peptide bioregulators, researchers frequently contrast its molecular parameters with structurally related compounds such as Epitalon and Thymogen. Each peptide presents distinct target affinities and amino acid compositions tailored for specific signaling pathways.
While Vilon (Lys-Glu) focuses heavily on chromatin unraveling and lymphocyte signaling, Epitalon research peptides (Ala-Glu-Asp-Gly) target telomerase activation and pineal gland gene expression. Simultaneously, Thymogen research compounds (Glu-Trp) are primarily evaluated for cell-surface receptor binding on immune cell subpopulations. Investigating these comparative dynamics allows research teams to isolate specific signaling mechanisms across multi-compound screening panels.
Maintaining structural integrity during reconstitution is critical for reproducible receptor binding and binding affinity assays. Lyophilized Vilon should be stored at -20°C or -80°C in a desiccated environment to prevent premature hydrolytic degradation.
For standard laboratory protocols, reconstitute lyophilized Vilon using sterile, endotoxin-free water or PBS under a laminar flow hood. Gently swirl or invert the vial until fully dissolved; avoid vigorous mechanical vortexing, which can induce peptide aggregation or denaturation. Reconstituted aliquots should be stored at 4°C for short-term assays or flash-frozen in liquid nitrogen and kept at -80°C for extended experimentation. For step-by-step dilution formulas, refer to our peptide reconstitution calculator guide.
When selecting a vendor to buy Vilon receptor binding supplier products, laboratory directors must enforce strict quality verification criteria. Low-purity peptide batches containing truncated sequences, residual counter-ions, or organic solvents introduce uncontrolled variables that invalidate binding affinity data.
High-quality suppliers provide lot-specific COAs incorporating both High-Performance Liquid Chromatography (HPLC) to establish purity percentages (>98%) and Mass Spectrometry (MS) to verify precise molecular mass. Additionally, verifying low bacterial endotoxin levels via Limulus Amebocyte Lysate (LAL) testing is critical when working with sensitive cell culture systems susceptible to lipopolysaccharide-induced inflammatory artifacts.

What primary receptor targets are evaluated in Vilon binding assays?
Preclinical literature indicates Vilon targets histone proteins and nuclear chromatin structures, modulating gene promoter accessibility rather than relying exclusively on classical membrane-bound GPCR signaling.
How does PX1 Research verify Vilon peptide purity?
Every lot of Vilon undergoes analytical testing using RP-HPLC to confirm >98% chemical purity and electrospray ionization mass spectrometry (ESI-MS) to confirm precise molecular mass.
What are the recommended storage conditions for lyophilized Vilon?
Lyophilized Vilon should be stored desiccated at -20°C to -80°C. Upon reconstitution, aliquots should be kept at -80°C to prevent degradation across repeated freeze-thaw cycles.
What solvent is recommended for reconstituting Vilon for in vitro assays?
Sterile bacteriostatic water, sterile water for injection, or phosphate-buffered saline (PBS, pH 7.4) are suitable solvents for dissolving Vilon for cell culture and enzymatic assays.
Are PX1 Research compounds suitable for clinical administration?
No. All products sold by PX1 Research, including Vilon, are strictly intended for laboratory research use only and are not for human or animal consumption or clinical use.
