Buy Epitalon 10mg

Direct Overview: Sourcing Epitalon 10mg for Laboratory Research

To buy Epitalon 10mg for laboratory research use, investigators require verified purity, lot-specific documentation, and precise molecular identity. Epitalon is a synthetic pineal tetrapeptide (Ala-Glu-Asp-Gly) supplied as a lyophilized 10mg powder for in vitro and preclinical models investigating telomerase expression, cellular senescence, and neuroendocrine regulation.

When purchasing research compounds for quantitative bioassays, experimental reproducibility depends entirely on chemical purity and exact lot consistency. Low-grade peptides containing truncated sequence artifacts, residual synthesis solvents, or elevated bacterial endotoxins obscure cellular responses and compromise assay integrity. PX1 Research fulfills these requirements by delivering domestic, ISO 17025-verified Epitalon 10mg equipped with full spectral documentation for demanding laboratory protocols.

Molecular Architecture and Structure of Epitalon

Epitalon (also designated as Epithalon or L-alanyl-L-alpha-glutamyl-L-alpha-aspartyl-glycine) is a short synthetic peptide comprising four amino acids: L-Alanine, L-Glutamic acid, L-Aspartic acid, and Glycine. Its primary chemical structure features a molecular formula of C16H26N4O9 and a exact molecular weight of 390.35 g/mol.

Developed initially through reverse-engineering of the bovine pineal gland extract known as Epithalamin, Epitalon represents a targeted short-chain peptide bioregulator. Because of its minimal molecular size, Epitalon exhibits low steric hindrance, permitting direct interactions with nuclear DNA, chromatin structures, and specific promoter regions in cell-free and cultured somatic cell systems.

Primary Mechanism: Telomerase Activation and Chromatin Interactions

The primary focus of preclinical inquiry surrounding Epitalon centers on its capacity to activate the enzyme telomerase. Telomerase is a ribonucleoprotein complex responsible for adding hexanucleotide repeats (5'-TTAGGG-3') to the 3' end of chromosomal DNA, thereby maintaining telomere length and preventing premature replicative arrest.

In vitro models utilizing human somatic fibroblasts demonstrate that exposure to Epitalon induces expression of human telomerase reverse transcriptase (hTERT), the catalytic subunit of the telomerase complex. Preclinical genomic assays indicate that Epitalon binds directly to histones and promoter regions of the hTERT gene, promoting histone acetylation and chromatin decondensation. This epigenetic mechanism enables RNA polymerase access without altering the underlying genomic sequence.

Pineal Regulation and Circadian Rhythm Synchronization

Beyond chromosomal maintenance, Epitalon acts as a functional pineal bioregulator. The pineal gland plays a central role in orchestrating systemic circadian rhythms through the pulsatile secretion of melatonin. As biological systems age, pineal sensitivity diminishes, leading to blunted nocturnal melatonin surges and circadian desynchronization.

In animal studies using rodent and non-human primate models, administration of Epitalon demonstrated a profound capacity to restore juvenile patterns of nocturnal melatonin synthesis. In vitro pinealocyte culture models suggest that Epitalon upregulates key rate-limiting enzymes in the melatonin biosynthesis pathway, including serotonin N-acetyltransferase (AANAT). By restoring endogenous melatonin output, Epitalon serves as a vital tool in investigating circadian bioenergetics, oxidative stress buffering, and neuroendocrine homeostasis.

Preclinical Longevity and Cellular Senescence Findings

Extensive preclinical literature highlights Epitalon's utility in models evaluating lifespan modification and cellular senescence. In vitro experiments on late-passage human somatic cell cultures revealed that Epitalon treatment overcome the classical Hayflick limit, allowing cells to undergo additional population doublings while maintaining normal karyotypic stability and suppressing senescent-associated beta-galactosidase activity.

In vivo longevity assays conducted in rodent species (including standard laboratory mice and rats) demonstrated statistically significant increases in maximum and mean lifespan following periodic administration regimens. Researchers observed reduced rates of spontaneous tumor formation, improved immune cell function, and preserved antioxidant enzyme expression (such as superoxide dismutase and glutathione peroxidase). These findings position Epitalon as a primary reference compound for investigating anti-senescence interventions in laboratory settings.

Comparative Analysis: Epitalon vs. Related Longevity and Bioregulator Peptides

When designing comparative preclinical protocols, researchers often evaluate Epitalon alongside other longevity-focused peptides and mitochondrial bioregulators. While Epitalon acts predominantly through nuclear chromatin remodeling and telomerase activation, alternative compounds engage distinct cellular pathways.

For instance, Thymalin is an immunomodulatory peptide bioregulator that targets T-cell differentiation within the thymus rather than direct hTERT expression. Similarly, MOTS-c is a mitochondrial-derived peptide that operates primarily on metabolic homeostasis, AMPK activation, and insulin sensitivity. Another frequently studied agent, FOXO4-DRI, functions explicitly as a senolytic peptide by disrupting the FOXO4-p53 interaction to induce apoptosis in senescent cells. Understanding these divergent mechanisms allows laboratory teams to design multi-targeted research protocols examining cellular aging from nuclear, mitochondrial, and senolytic perspectives.

Epitalon 10mg Reconstitution and In Vitro Preparation

Epitalon 10mg is supplied as a sterile, lyophilized cake inside a clear glass vial. To ensure accurate pipetting and stable stock solution concentrations, precise reconstitution procedures must be observed in a laminar flow hood using aseptic technique.

Reconstitution should be performed using high-purity laboratory diluents such as sterile bacteriostatic water (containing 0.9% benzyl alcohol) or sterile phosphate-buffered saline (PBS, pH 7.4) depending on the downstream assay criteria. For standard 10mg vials, slowly adding 2.0 mL of diluent along the internal glass wall yields a final stock concentration of 5.0 mg/mL (5.0 mcg/uL). Direct forceful agitation should be avoided; gentler vortexing or manual rotation of the vial ensures complete dissolution without mechanical shear of the peptide chain.

Laboratory Storage, Thermal Stability, and Handling

Lyophilized Epitalon 10mg exhibits high thermal stability in its dry state. When stored in a temperature-controlled freezer at -20°C or -80°C, the sealed powder remains stable for up to 24 months without significant peptide degradation.

Once reconstituted into aqueous solution, the peptide becomes more susceptible to hydrolysis and enzymatic cleavage. Reconstituted stock solutions intended for short-term use (up to 21 days) should be stored refrigerated at 2°C to 8°C. For long-term storage of reconstituted aliquots, solutions should be frozen at -20°C or -80°C in single-use microcentrifuge tubes to eliminate repeat freeze-thaw cycles, which induce structural breakdown.

Analytical Verification: HPLC, Mass Spectrometry, and Endotoxin Standards

Quantification and purity assurance are crucial for maintaining experimental repeatability in published science. PX1 Research submits every batch of Epitalon 10mg to independent, ISO 17025-accredited testing facilities for rigorous physical and chemical analysis.

High-Performance Liquid Chromatography (RP-HPLC) is utilized to determine overall chemical purity, requiring a threshold of >= 98.0% (typically exceeding 99.0%). Electrospray Ionization Mass Spectrometry (ESI-MS) confirms the exact molecular mass (390.35 Da), verifying sequence identity and the absence of post-synthesis adducts. Furthermore, Chromogenic LAL (Limulus Amebocyte Lysate) testing is performed on every lot to guarantee endotoxin levels remain strictly below < 0.01 EU/mg, preventing unwanted immune activation in cell cultures or animal models.
