Epithalon 5mg — Vial Spec, Reconstitution Math & COA

Epithalon 5mg Vial Overview and Catalog Availability

In laboratory research, the 5mg lyophilized vial specification of Epithalon serves as a standard working unit for medium-throughput in vitro experiments and focused rodent studies. Epithalon (also known as Epitalon or L-alanyl-L-alpha-glutamyl-L-alpha-aspartyl-glycine) is a synthetic short-chain peptide modeled after pineal gland secretions. A 5mg mass allocation provides research laboratories with sufficient peptide material to conduct multiple assay replicates while minimizing the ambient exposure and thaw cycles inherent to larger bulk quantities.

While PX1 Research stocks high-purity synthetic bioregulators across multiple configurations in our all-peptides inventory, exact single-vial unit sizes can vary based on current batch manufacturing runs. Investigators seeking to source this specific bioregulator can evaluate our standard high-purity epithalon product listing to verify current lot specifications, fill sizes, and bulk availability. Regardless of vial mass, all PX1 Research compounds are manufactured in domestic GMP-compliant facilities and undergo rigorous third-party analytical verification.

Molecular Structure and Bioregulator Class Mechanism

Epithalon is categorized structurally and functionally as a peptide bioregulator. It comprises a four-amino-acid sequence: Ala-Glu-Asp-Gly (A-E-D-G), with a molecular formula of C14H22N4O9 and a molecular weight of approximately 390.35 g/mol. As a synthetic pineal peptide derivative, its primary biochemical mechanism involves interactions with genomic DNA and chromatin structures within target cell nuclei.

Preclinical studies suggest that short peptide bioregulators like Epithalon act as gene expression modulators. In vitro research indicates that the Ala-Glu-Asp-Gly sequence binds directly to specific histone proteins and DNA promoter regions, facilitating the unwinding of heterochromatin into transcriptionally active euchromatin. This epigenetic interaction is believed to regulate the transcription of genes associated with cellular repair, protein synthesis, and enzymatic output in pineal and somatic tissue models.

Preclinical Research Focus: Telomerase Activation and Circadian Modulation

The primary focus of Epithalon investigation in literature centers on its capacity to activate human telomerase reverse transcriptase (hTERT) and maintain telomeric length in aging cell lines. In vitro assays using somatic human fibroblasts demonstrate that exposure to Epithalon induces telomerase catalytic activity, enabling cells to overcome the Hayflick limit and undergo additional division cycles without exhibiting chromosomal instability.

Beyond telomere maintenance, preclinical rodent models indicate that Epithalon exerts a regulating effect on the neuroendocrine system, specifically the pineal-hypothalamic axis. In aging murine models, administration of the tetrapeptide demonstrated restoration of nocturnal melatonin secretion patterns, attenuation of oxidative stress markers, and normalisation of circadian endocrine cycles. These findings position Epithalon as a core benchmark compound within broader research on metabolic health and biological aging in our research library hub.

Volumetric Reconstitution Calculations for a 5mg Vial

Accurate reconstitution of a 5mg lyophilized Epithalon vial requires precise volumetric planning using sterile laboratory diluents, such as bacteriostatic water (0.9% benzyl alcohol) or sterile physiological saline (0.9% NaCl). To achieve targeted microgram (µg) or milligram (mg) concentrations per unit volume, research staff must calculate final concentrations prior to liquid transfer. You can quickly calculate precise draw volumes using our integrated reconstitution calculator.

Adding 1.0 mL of diluent to a 5mg cake yields a concentration of 5.0 mg/mL (5,000 µg per 1.0 mL, or 500 µg per 0.1 mL draw). Introducing 2.0 mL of diluent lowers the concentration to 2.5 mg/mL (2,500 µg per 1.0 mL, or 250 µg per 0.1 mL draw). For low-concentration assays requiring fine volumetric control, adding 3.0 mL of diluent yields approximately 1.67 mg/mL (1,666.7 µg per 1.0 mL, or 166.7 µg per 0.1 mL draw). Laboratories should always select a diluent volume that aligns with the pipette precision limits of their analytical equipment.

Aliquot Protocol and Laboratory Storage Parameters

Lyophilized Epithalon 5mg vials exhibit high chemical stability when stored under controlled environment conditions. Sealed, un-reconstituted vials should be kept in a dark freezer at -20°C or below, protected from light exposure, where they remain stable for up to 24 months. For short-term transit or immediate storage prior to protocol execution, sealed vials may be held at 2°C to 8°C for limited durations.

Once reconstituted with a sterile liquid medium, the peptide undergoes gradual hydrolytic degradation. To preserve peptide integrity, reconstituted solutions stored at 2°C to 8°C should be utilized within 14 to 28 days if prepared with bacteriostatic diluent. For long-term preservation of liquid stock solutions, laboratories should divide the reconstituted solution into single-use micro-aliquots using sterile polypropylene tubes and store them at -80°C. Repeated freeze-thaw cycles must be rigorously avoided, as physical phase changes induce mechanical shearing of the peptide structure.

Analytical Verification: HPLC, Mass Spectrometry, and COA Standards

Maintaining rigorous experimental reproducibility requires verified compound purity. PX1 Research enforces strict quality control standards across all peptide fills. Every production lot undergoes comprehensive analytical validation at an independent ISO 17025 accredited laboratory prior to release. Laboratories can easily inspect lot-specific testing metrics on our dedicated certificate of analysis portal.

Analytical protocols include High-Performance Liquid Chromatography (HPLC) to establish purity thresholds exceeding 99.0%, alongside Mass Spectrometry (MS) to verify precise theoretical molecular mass (390.35 Da). Furthermore, every lot undergoes Chromogenic Reagent LAL assay testing to confirm endotoxin levels fall strictly below standard research limits (<0.1 EU/mg). This ensures that cellular cultures and animal tissue models remain free from bacterial lipopolysaccharide contamination that could confound inflammatory markers.

Comparative Analysis: Epithalon vs. Related Bioregulators and Longevity Peptides

When designing protocols investigating tissue regeneration and cellular lifespan, researchers often evaluate Epithalon alongside other specialized bioregulators and synthetic peptides. For instance, while Epithalon modulates telomerase activity and pineal regulation, the thymic peptide thymalin is routinely investigated for its distinct role in T-cell differentiation and immune system homeostasis. Similarly, senolytic agents such as foxo4-dri target the selective apoptosis of senescent cells rather than telomere maintenance, and mitochondrial-derived peptides like mots-c regulate metabolic homeostasis and AMPK pathways. Understanding these distinct molecular mechanisms allows laboratories to construct comprehensive multi-peptide comparative frameworks.

Selecting Optimal Mass Specifications: 5mg vs. Alternate Fills

Determining whether a 5mg vial specification or a larger fill size is appropriate depends on experimental design, assay volume, and subject group size. A 5mg vial is ideal for small-scale pilot studies, short-duration rodent trials, or in vitro cell culture treatments where stock solutions must be freshly prepared every few weeks. Utilizing 5mg units prevents waste associated with degraded liquid storage over multi-month protocols.

Conversely, high-throughput screening projects or long-term multi-cohort animal trials may benefit from larger unit specifications or bulk orders to minimize batch-to-batch variation and lower unit costs. Laboratories managing continuous research programs can establish custom supply arrangements through a lab wholesale account to ensure stable batch continuity across multi-phase experimental designs.

Laboratory Safety, Handling Practices, and Waste Disposal

Epithalon 5mg is strictly designated as a chemical reagent intended for laboratory research use only by qualified scientific personnel. It is explicitly not for human, clinical, therapeutic, or veterinary applications. Research personnel handling lyophilized powder or liquid solutions must observe standard Biosafety Level 1 or 2 practices, including wearing nitrile gloves, lab coats, and protective eyewear inside a certified laminar flow hood.

In the event of accidental skin or eye contact, the affected area should be flushed immediately with copious amounts of water or saline. Discarded vials, used pipettes, and residual reconstituted liquid must be processed through designated biohazard or chemical hazardous waste streams in full compliance with local, state, and institutional environmental safety regulations.
