Epithalon For Sale — Research Grade

Source High-Purity Epithalon for Laboratory Research

In the field of peptide bioregulation and molecular gerontology, acquiring analytical-grade compounds with verified purity is critical for reproducible experimental outcomes. PX1 Research supplies high-purity Epithalon for sale to support precise scientific investigation into synthetic short-chain peptides.

Epithalon (also known as Epitalon or L-alanyl-L-alpha-glutamyl-L-alpha-aspartylglycine) is synthesized using automated solid-phase peptide synthesis (SPPS). This manufacturing standard eliminates truncated peptide sequences, residual TFA salts, and organic solvents, yielding a refined lyophilized powder suitable for cell culture, enzymatic assays, and animal model studies.

To ensure institutional compliance, every batch of our research-grade Epithalon powder is held to strict quality benchmarks. Researchers are provided with batch-specific documentation to confirm chemical identity, sequence integrity, and precise mass determination prior to initiating controlled laboratory protocols.

Biochemical Profile and Structural Characteristics of Epithalon

Epithalon is a synthetic tetrapeptide with the primary amino acid sequence Ala-Glu-Asp-Gly (AEDG). It was originally designed to emulate the biological activity of Epithalamin, a crude pineal gland peptide extract investigated in early Soviet peptide bioregulation studies.

With a molecular formula of C14H22N4O9 and a molecular weight of 390.35 g/mol, Epithalon belongs to the short-chain bioregulator peptide class. Unlike long-chain polypeptide hormones, short peptide sequences like AEDG can penetrate cell membranes and interact directly with nucleosomes and promoter regions of DNA.

The small molecular footprint of Epithalon allows high solubility in standard aqueous physiological buffers, such as phosphate-buffered saline (PBS) and 0.9% sterile sodium chloride, facilitating predictable concentration gradients during in vitro assays.

Primary Mechanism of Action: Telomerase Expression and Telomere Maintenance

The primary locus of scientific interest regarding Epithalon centers on its capability to induce telomerase activity. Preclinical data indicate that Epithalon upregulates the enzymatic expression of telomerase reverse transcriptase (TERT), the catalytic subunit responsible for adding hexanucleotide repeats (TTAGGG) to the ends of eukaryotic chromosomes.

In somatic cell culture models, progressive telomere attrition leads to replicative senescence and cell cycle arrest. In vitro studies demonstrate that the addition of Epithalon to cultured human diploid fibroblasts promotes chromatin decondensation, permitting RNA polymerase access to the promoter region of the TERT gene. Further details on comparative cellular protocols are available in the PX1 cellular senescence research hub.

By stabilizing telomere length, Epithalon allows researchers to examine cellular longevity, DNA damage responses, and the bypass of Hayflick limits without altering underlying oncogenic pathways or causing genomic instability.

Pineal Axis Dynamics and Circadian Regulation in Preclinical Models

Beyond its direct nuclear interactions, Epithalon is routinely investigated for its regulatory effects on the neuroendocrine system, specifically the pineal-hypothalamic axis. The pineal gland plays a central role in governing circadian rhythms through the cyclical synthesis of melatonin.

In animal models, particularly aging rodents and non-human primates, preclinical studies suggest that Epithalon administration restores nocturnal melatonin synthesis toward levels observed in younger control cohorts. This restoration occurs via the enzymatic upregulation of serotonin N-acetyltransferase (AANAT), a rate-limiting enzyme in melatonin biosynthesis.

Additionally, laboratory findings indicate that Epithalon-mediated pineal regulation correlates with reduced markers of oxidative stress, including lower malondialdehyde (MDA) levels and upregulated activity of endogenous antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPx).

Comparative Analysis: Epithalon vs. Related Bioregulator Peptides

When designing comparative study protocols within gerontology and tissue regeneration, researchers frequently evaluate Epithalon alongside other targeted synthetic peptides. Epithalon acts primarily as a systemic telomerase activator and pineal modulator. In contrast, Pinealon (Glu-Asp-Arg) targets central nervous system tissue, exhibiting neuroprotective effects in cerebral ischemia models. Meanwhile, Thymalin serves as a thymic peptide complex focused on T-cell differentiation and immune system bioregulation, while GHK-Cu peptide functions as a copper-binding tripeptide that modulates extracellular matrix remodeling and gene expression in dermal and connective tissues.

Understanding these distinct tissue affinities and signaling pathways allows investigators to select the appropriate single compound or combination protocol for multi-system preclinical investigations.

Quality Verification: HPLC, Mass Spectrometry, and Endotoxin Limits

At PX1 Research, analytical precision is paramount. Every batch of Epithalon undergoes mandatory testing through independent, ISO 17025-accredited testing laboratories to verify structural identity and purity thresholds prior to release.

Purity is assessed using reverse-phase high-performance liquid chromatography (RP-HPLC), ensuring a minimum threshold of 98.0% peptide purity. Chromatographic profiles confirm the absence of synthesis byproducts, truncated fragments, or heavy metal contamination.

Electrospray ionization mass spectrometry (ESI-MS) confirms exact mass matches to the theoretical molecular weight of 390.35 Da. Crucially for cell culture integrity, every lot undergoes chromogenic Limulus Amebocyte Lysate (LAL) testing to verify endotoxin levels remain strictly below <0.01 EU/mg, preventing non-specific inflammatory responses in sensitive biological assays.

Laboratory Reconstitution and Storage Parameters

To preserve the structural stability of lyophilized Epithalon upon delivery, receiving laboratories should adhere to standard aseptic handling protocols. Lyophilized vials should be stored at -20°C for long-term stability or 2°C to 8°C for immediate experimental use within 30 days.

Reconstitution should be performed using sterile 0.9% Sodium Chloride or Bacteriostatic Water for Injection. The solvent should be gently introduced along the inner glass wall of the vial, followed by low-speed swirling. Mechanical agitation or vigorous vortexing must be avoided to prevent peptide shear or aggregation.

Once reconstituted, working aliquots should be prepared in sterile polypropylene tubes and frozen at -20°C or -80°C to avoid degradation resulting from repeated freeze-thaw cycles. Reconstituted solutions maintain stability for up to 21 days when stored continuously at 2°C to 8°C.

Procurement and Distribution via PX1 Research

PX1 Research operates dedicated fulfillment facilities in California and Arizona to support fast, reliable distribution to scientific facilities across the United States. Orders submitted prior to cutoff times Monday through Friday are processed with same-day dispatch.

All shipments are packaged with thermal protective measures and secure casing to maintain chemical integrity during transit. Researchers seeking large-volume lots or recurring fulfillment schedules can establish a institutional wholesale research account to access direct account management and volume-tiered pricing structures.

In Vitro Protocols and Experimental Application Methodologies

In vitro assays incorporating Epithalon typically utilize concentration ranges between 0.1 µM and 10 µM, dependent on cell line sensitivity and target endpoints. Researchers studying fibroblast replicative lifespans apply Epithalon during early or mid-passage phases to measure changes in population doubling levels (PDLs) and beta-galactosidase expression.

In animal model frameworks, researchers investigate parameters including circadian gene expression (e.g., CLOCK, BMAL1), lipid peroxidation rates, and structural integrity of hypothalamic nuclei. All procedures involving research peptides supplied by PX1 must conform strictly to institutional biosafety guidelines and institutional animal care policies.
