Epithalon 60mg — Vial Spec, Reconstitution Math & COA

Epithalon 60mg Vial Overview & High-Yield Applications

The 60mg Epithalon vial format is formulated to meet the requirements of academic and industrial research facilities executing large-scale cell culture assays, longitudinal rodent models, or high-density automated pipetting workflows. In laboratory settings, managing single high-yield vials reduces batch-to-batch variability by establishing a uniform stock solution for long-term experimental runs.

Epithalon (a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly) serves as a targeted bioregulator peptide in preclinical research models. Principal investigative domains include telomerase activation mechanisms, telomere length maintenance, and pineal gland gene expression related to circadian alignment. Laboratories requiring high total peptide mass often select the 60mg vial format to simplify stock solution preparation, minimize packaging waste, and maintain consistency across extended experimental timelines.

At PX1 Research, high-yield formats undergo rigorous fill-finish controls. While standard inventory frequently centers on smaller mass options like the Epithalon 10mg product format, custom or high-yield configurations such as 60mg are manufactured and analyzed under the same strict quality guidelines. Researchers requiring specialized bulk sizing can consult our wholesale lab account portal for custom batch allocations.

Chemical Structure, Molecular Weight, and Mechanism

Epithalon is a synthetic short-chain peptide derived from the naturally occurring pineal peptide complex known as epithalamin. Structurally, it consists of four amino acids with a molecular formula of C14H22N4O9 and a exact molecular weight of approximately 390.35 g/mol. Due to its short sequence length, the peptide exhibits excellent aqueous solubility and structural stability under controlled pH conditions.

Preclinical studies suggest that Epithalon interacts directly with chromatin structures within cellular nuclei, facilitating epigenetic regulation. In vitro models utilizing human somatic cells and rodent tissue cultures demonstrate that Epithalon application promotes the expression of the catalytic subunit of telomerase (TERT). This enzymatic activation supports telomere elongation and maintains genomic integrity during extended cellular division cycles.

Additionally, animal study models indicate that Epithalon exerts regulatory effects on the pineal gland, promoting the normalization of melatonin synthesis and resetting disrupted circadian rhythms.

Reconstitution Math for 60mg Epithalon Vials

Reconstituting a 60mg lyophilized cake requires precise volumetric calculation to achieve the target working concentration for automated microtiter plates or cell culture dosing protocols. Laboratories must use sterile, laboratory-grade bacteriostatic water or sterile phosphate-buffered saline (PBS, pH 7.4) depending on downstream assay requirements.

Below are the calculated concentration yields for a 60mg vial based on standard diluent addition volumes:

• 1.0 mL Diluent Volume: Reconstitution with 1.0 mL yields a final stock concentration of 60.0 mg/mL (60.0 µg/µL). This high concentration is ideal for concentrated stock storage or low-volume micro-injection setups. • 2.0 mL Diluent Volume: Reconstitution with 2.0 mL yields a final stock concentration of 30.0 mg/mL (30.0 µg/µL). This intermediate concentration allows for highly accurate volumetric measurements using standard laboratory micropipettes. • 3.0 mL Diluent Volume: Reconstitution with 3.0 mL yields a final stock concentration of 20.0 mg/mL (20.0 µg/µL). This dilution is well-suited for high-volume in vitro assays or serial dilution series across multi-well plates.

Aliquot Planning & Diluent Compatibility Protocols

When handling high-yield peptide stocks like 60mg Epithalon, repeat freeze-thaw cycles must be strictly avoided to prevent physical degradation or chemical cleavage of the peptide chain. Immediately following primary reconstitution, stock solutions should be divided into single-use micro-aliquots using sterile, low-protein-binding polypropylene microcentrifuge tubes.

For aqueous reconstitution, bacteriostatic water containing 0.9% benzyl alcohol is recommended if the reconstituted solution will be stored at 2°C to 8°C over short experimental windows (up to 28 days). If the reconstituted stock is intended for immediate frozen storage (-20°C or -80°C) or sensitive cell culture applications where benzyl alcohol may induce cytotoxicity, sterile 0.9% sodium chloride or isotonic PBS should be used instead.

Every aliquot container should be clearly labeled with the peptide identity, final calculated concentration, reconstitution date, and lot number matching the accompanying analytical documentation.

Thermal Stability & Long-Term Storage Guidelines

Lyophilized Epithalon exhibits robust thermal stability when stored under vacuum conditions in moisture-impermeable borosilicate glass vials. Upon receipt from PX1 Research, sealed lyophilized 60mg vials should be stored at -20°C for long-term preservation (up to 24 months) or at 2°C to 8°C for short-term operational windows (up to 90 days). Vials must be protected from direct light exposure.

Prior to reconstitution, the sealed vial must be allowed to equilibrate to room temperature (20°C to 25°C) for approximately 30 to 45 minutes. Opening a cold vial in a humid room causes immediate condensation on the lyophilized cake, which can accelerate hydrolytic degradation and alter calculated peptide mass.

Once reconstituted into aqueous liquid form, aliquots stored at -20°C remain stable for up to 3 to 6 months, while storage at -80°C extends stability up to 12 months. Frozen stock should be thawed slowly on ice prior to execution of analytical procedures. Detailed thermal stability parameters are published in our peptide storage and handling guide.

COA Verification: HPLC, MS, and Endotoxin Limits for 60mg Lots

Every batch of Epithalon produced for PX1 Research undergoes rigorous third-party testing at accredited ISO 17025 testing laboratories. Analytical verification is non-negotiable for high-concentration vials, as structural impurities or residual solvents directly impact assay outcomes.

Analytical documentation provided with each lot includes:

1. High-Performance Liquid Chromatography (HPLC): Confirms chemical purity relative to total peak area. Epithalon lots must demonstrate ≥98.0% purity, with individual impurities capped below strict threshold limits. 2. Mass Spectrometry (MS): Electrospray ionization mass spectrometry (ESI-MS) confirms the exact molecular mass (390.35 Da) and rules out structural deletions or incomplete synthesis chains. 3. Endotoxin Testing (LAL Assay): Kinetic chromogenic LAL testing verifies that bacterial endotoxin levels remain below <0.01 EU/mg, protecting sensitive cell culture environments from lipopolysaccharide-induced inflammatory responses.

Researchers can inspect authentic, lot-matched analytical reports directly via our certificate of analysis database.

Comparing Formats: 10mg vs. 60mg Epithalon Vials

Selecting between a standard 10mg Epithalon vial and a 60mg high-yield format depends primarily on scale, pipeline frequency, and dilution volume constraints. For small-scale pilot studies, initial dose-response screens, or short-duration animal models, the 10mg Epithalon format provides sufficient material while minimizing the need for extended frozen storage of reconstituted liquid stock.

Conversely, the 60mg vial format offers significant operational advantages for high-throughput laboratory environments. Preparing a single 60mg vial reduces total handling time, decreases reagent consumption during reconstitution, and eliminates inter-vial variation across multi-plate screens. Facilities conducting extensive bioregulator screening or parallel experimental arms achieve greater analytical consistency by utilizing a single high-concentration stock batch.

If a specific high-yield size is temporarily out of stock on the primary portal, laboratories can review current stock status across our research peptide directory or request prioritized batch allocation via our enterprise team.

Bioregulator Class Comparison: Epithalon, Pinealon, and GHK-Cu

Within preclinical research, Epithalon belongs to a distinct class of short-chain peptide bioregulators evaluated alongside other synthetic pineal and tissue-specific signaling molecules. Comparing mechanisms across related compounds helps investigators select optimal peptides for specific cell culture or animal models.

For example, while Epithalon targets nuclear chromatin to influence telomerase expression and pineal output, Pinealon is a synthetic tripeptide (Glu-Asp-Arg) evaluated predominantly in central nervous system models for neuroprotective and circadian signal regulation. Similarly, GHK-Cu is a tripeptide-copper complex investigated for gene remodeling, extracellular matrix synthesis, and tissue repair pathways, operating via distinct enzymatic and transcriptional cascades. In immune system signaling research, researchers frequently study Thymalin alongside pineal bioregulators to evaluate neuroendocrine-immune network cross-talk.
