This guide provides an analytical framework for principal investigators and laboratory procurement officers seeking verified research-grade Epithalon for preclinical research.
For institutional investigators evaluating epithalon vente en ligne options, purchasing Epithalon (Ala-Glu-Asp-Gly) online requires selecting ISO 17025-verified suppliers that offer lot-specific Certificate of Analysis (COA) documentation. Validated laboratory supply ensures greater than 99% peptide purity confirmed via reverse-phase HPLC and mass spectrometry, accompanied by quantitative bacterial endotoxin testing for rigorous in vitro and preclinical experimentation.
The digital procurement of specialized research chemicals requires careful scrutiny of manufacturing facilities and quality control protocols. When seeking epithalon online sourcing, analytical laboratories must distinguish between research-grade reagents intended strictly for in vitro assays and unverified grey-market products lacking batch traceability. PX1 Research manufactures all compounds within USA-based, cGMP-compliant facilities to supply international and domestic laboratories with reliable research materials.
Epithalon is a synthetic tetrapeptide composed of the amino acid sequence L-alanyl-L-alpha-glutamyl-L-alpha-aspartyl-glycine (H-Ala-Glu-Asp-Gly-OH). It was originally developed based on native polypeptide extracts isolated from the pineal gland, termed epithalamin. Through peptide synthesis, researchers isolated the active core tetrapeptide to study its specific downstream signaling cascades without the batch-to-batch variability inherent in crude organo-extracts.
With a molecular formula of C16H26N4O9 and a molecular mass of approximately 418.4 g/mol, Epithalon belongs to the class of short short-chain peptide bioregulators. In vitro research published in peptide research archives suggests that short-chain bioregulators interact directly with non-histone chromatin proteins and specific promoter regions of DNA, facilitating targeted gene transcription without altering the primary genomic sequence.
The primary biochemical target of Epithalon in cell culture models is the catalytic subunit of the telomerase enzyme complex, human telomerase reverse transcriptase (hTERT). Preclinical studies in human somatic cell models indicate that exposure to Epithalon induces telomerase activation, leading to the enzymatic elongation of telomeric repeats (TTAGGG) at chromosome ends. This process counteracts progressive telomere attrition typically observed across serial cell passages.
In vitro assays evaluating somatic fibroblasts demonstrated that Epithalon application promotes chromatin decondensation, enabling transcriptomic machinery to access heterochromatic regions. By upregulating hTERT gene expression, Epithalon allows cultured cell lines to overcome the Hayflick limit—the finite boundary of cell divisions—without exhibiting oncogenic transformation or karyotypic instability. These mechanisms position Epithalon as a core reference molecule in telomere dynamics research.
Beyond its direct interaction with telomerase, Epithalon has been extensively evaluated for its regulatory effects on pineal gland function and circadian clock gene expression. In rodent and non-human primate models, administration of pineal-derived short peptides was observed to restore night-peak melatonin secretion in aging subjects, suggesting a role in resetting central neuroendocrine rhythms.
In vitro co-culture assays show that Epithalon modulates the expression of arylalkylamine N-acetyltransferase (AANAT), the rate-limiting enzyme in melatonin biosynthesis. By stabilizing pinealocyte metabolic output, the peptide influences peripheral circadian gene networks, including CLOCK, BMAL1, and PER2. Research laboratories utilize pineal research compounds to investigate chronobiology and age-related hormonal desynchronization.
When designing preclinical assays targeting cellular aging, metabolic stress, or neuroendocrine decay, investigators frequently compare Epithalon against other bioregulatory peptides. Understanding the distinctive pathways of each compound allows for precise experimental design and targeted variable isolation.
Epithalon primarily targets telomerase expression and pineal melatonin synthesis. In contrast, Pinealon is a tripeptide (Glu-Asp-Arg) specifically focused on neuroprotective gene expression, reactive oxygen species (ROS) reduction in neuronal cultures, and central nervous system repair models. Meanwhile, MOTS-c is a mitochondrially derived peptide that exerts control over metabolic homeostasis, AMPK activation, and insulin sensitivity. While Epithalon regulates nuclear genomic stability via telomere length maintenance, MOTS-c modulates mitochondrial-nuclear communication under metabolic stress conditions. Researchers can explore the full range of bioregulators via the all peptides catalogue.
For researchers sourcing epithalon vente en ligne, verifying product quality is vital to prevent experimental confounding. Low-grade research compounds may contain residual coupling reagents, truncated peptide fragments, heavy metals, or bacterial endotoxins that invalidate assay results.
PX1 Research enforces strict analytical quality metrics for every lot of Epithalon produced:
• Purity Determination: Assessed via Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC). Qualified research lots must demonstrate ≥99.0% chemical purity with defined peak retention times.
• Mass Verification: Assessed via Electrospray Ionization Mass Spectrometry (ESI-MS) or MALDI-TOF to confirm the exact monoisotopic mass of 418.4 Da.
• Endotoxin Quantitation: Tested using Chromogenic Recombinant Factor C (rFC) or LAL assays to ensure endotoxin content remains strictly below <0.01 EU/mg, preventing baseline cytokine activation in cell cultures.
• Bioburden Testing: Lyophilized vials undergo sterility testing to verify the complete absence of bacterial and fungal contaminants.
A reliable Certificate of Analysis must originate from an independent, ISO 17025-accredited analytical testing laboratory. Investigators purchasing epithalon online should never rely on unverified internal supplier sheets or static template PDFs that lack batch-specific chromatograms.
Key components of an authentic PX1 Research COA include:
1. Unique Lot Number matching the physical sample vial label.
2. Raw RP-HPLC Chromatogram showing clean baseline separation, peak area integration tables, and absolute purity percentages.
3. High-Resolution Mass Spectrum displaying the primary structural mass peak without significant adducts or synthesis byproducts.
4. Date of Analysis and signature of certified analytical chemists.

Epithalon is supplied as a sterile, lyophilized (freeze-dried) powder to maximize chemical stability during transport and storage. Proper laboratory reconstitution and handling procedures are necessary to maintain peptide integrity:
• Reconstitution Medium: Lyophilized Epithalon should be reconstituted using sterile Bacteriostatic Water (0.9% benzyl alcohol) for multi-use analytical sampling or sterile 0.9% Sodium Chloride / Phosphate-Buffered Saline (PBS) for immediate cell culture applications.
• Technique: Direct the solvent against the inner glass wall of the vial. Allow the diluent to gently dissolve the cake without vigorous vortexing, which can cause mechanical shear stress or foam formation.
• Storage Conditions: Store unopened lyophilized vials at -20°C or -80°C for long-term preservation. Reconstituted aqueous solutions should be stored at 2°C to 8°C and used within 14 days, or aliquoted and stored at -80°C to avoid repeated freeze-thaw cycles.
High-throughput screening initiatives, long-term animal studies, and institutional core facilities require consistent, high-volume peptide supplies with identical lot characteristics. Variations between batches can introduce uncontrolled variables into long-term longitudinal studies.
