Scientific overview

Research summary: Short bioregulator peptide referenced in neuronal oxidative-stress models.

Pinealon is a synthetic tripeptide bioregulator from the same Russian research programme that produced Epitalon, developed as a short peptide with reported affinity for neuronal chromatin.

Mechanism of action

Described in the literature as penetrating the nuclear compartment of neuronal cells and interacting with regulatory DNA sequences, modulating expression of antioxidant and anti-apoptotic genes under hypoxic stress in culture models.

Areas of scientific investigation

Neuronal culture stress-response models
Peptide-DNA interaction studies
Hypoxia and oxidative-stress protection assays
Short-peptide bioregulator research

Listed fields describe where this sequence appears in published in vitro and preclinical literature. They are not indications, applications, or claims of effect.

Laboratory handling

Reconstitution

Allow the vial to reach room temperature before opening to prevent condensation on the lyophilized cake. Add sterile or bacteriostatic water slowly down the inner wall of the vial, then let the powder dissolve without agitation; swirl gently if needed. Do not shake or vortex – shear forces denature peptide secondary structure and cause foaming that traps material on the stopper.

Stability

As a sealed lyophilized powder the material is stable for extended periods at -20 °C when kept desiccated and protected from light. Once in solution, stability shortens considerably: aqueous stocks are normally held at 2-8 °C for short term work or aliquoted and frozen for longer storage. Repeated freeze-thaw cycling is the most common cause of measurable potency loss.

Packaging

Single sequence per vial, sealed under inert gas in USP Type I borosilicate glass with a butyl rubber stopper and crimped aluminium overseal. Each vial carries a printed PrimeGen label with product name, strength, lot number, manufacture and retest dates, storage temperature and a QR code linking to the lot record. Vials ship in a rigid foam insert inside a protective mailer at ambient temperature.

Pinealon 15 mg – laboratory research dossier

This dossier collects everything a laboratory typically needs before requisitioning Pinealon at the 15 mg presentation: how the sequence is characterised in published literature, how the material is assayed and released, how it should be stored and reconstituted, and where it sits inside the wider longevity & cellular research catalogue. Every unit is supplied as a sealed lyophilized powder released to a specification of ≥ 98% by RP-HPLC, with the measured value for each lot recorded on that lot’s certificate of analysis. It is sold exclusively for laboratory research use. It is not a drug, dietary supplement or cosmetic, and it is not intended for human or veterinary use.

Scientific background

Pinealon is a synthetic tripeptide bioregulator from the same Russian research programme that produced Epitalon, developed as a short peptide with reported affinity for neuronal chromatin.

Short bioregulator peptide referenced in neuronal oxidative-stress models. Investigators most often encounter this sequence in neuronal culture stress-response models and in peptide-dna interaction studies, which is why the 15 mg vial is the format we release most frequently – it gives enough material for a full dose-response series at typical assay concentrations without leaving a large reconstituted surplus to store. This compound is catalogued at 2 strengths (10 mg, 15 mg), so a study can be scaled without changing lot chemistry.

Mechanism of action in published work

Descriptions above summarise observations reported in peer reviewed in vitro and animal literature. They describe what has been measured in model systems and are not claims of effect, indications, or guidance for use in humans or animals. Laboratories designing new work should return to the primary literature for concentration ranges, vehicle selection and control design, because reported effects in this class are strongly assay dependent.

Research applications

Published work involving Pinealon clusters into a small number of recurring experimental settings:

Neuronal culture stress-response models
Peptide-DNA interaction studies
Hypoxia and oxidative-stress protection assays
Short-peptide bioregulator research

Because these are in vitro and preclinical contexts, the practical requirement on the material itself is consistency: a known mass of a single sequence, a stated purity, and a lot record that can be cited in a methods section. That is what the 15 mg vial and its accompanying certificate of analysis are designed to provide.

Purity, quality control and the certificate of analysis

Each Pinealon lot is assayed in house by reverse-phase HPLC and then re-tested by an independent analytical laboratory using HPLC alongside mass spectrometry for identity confirmation. The HPLC trace establishes the chromatographic purity figure recorded for the lot, which is released against a specification of ≥ 98% and reported on that lot’s certificate of analysis rather than quoted here as a fixed number – while the mass spectrometry step confirms that the observed molecular ion matches the expected mass for the sequence rather than a truncated or deletion analogue.

Certificates are issued digitally rather than enclosed in the shipment, which keeps the document versioned and retrievable long after the vial is consumed. You can view or request the current report from the certificates library, and the underlying chromatograms and spectra can be requested through laboratory support. Our full release criteria are documented on the quality control and laboratory standards pages.

Storage, reconstitution and stability

Storage. Sealed 15 mg vials are held desiccated and protected from light. Short holding periods at 2-8 °C are routine; for longer storage the lyophilized cake is kept at -20 °C. Allow the vial to equilibrate to room temperature before breaking the seal so that atmospheric moisture does not condense onto the powder.

Reconstitution. Allow the vial to reach room temperature before opening to prevent condensation on the lyophilized cake. Add sterile or bacteriostatic water slowly down the inner wall of the vial, then let the powder dissolve without agitation; swirl gently if needed. Do not shake or vortex – shear forces denature peptide secondary structure and cause foaming that traps material on the stopper.

Stability. As a sealed lyophilized powder the material is stable for extended periods at -20 °C when kept desiccated and protected from light. Once in solution, stability shortens considerably: aqueous stocks are normally held at 2-8 °C for short term work or aliquoted and frozen for longer storage. Repeated freeze-thaw cycling is the most common cause of measurable potency loss.

Handling. Work with the reconstituted solution under standard laboratory containment, record the reconstitution volume and date against the lot, and label aliquots with the resulting concentration. Volumes and concentrations are set by your own protocol; nothing on this page is a dosing instruction.

Experimental design considerations

The most common source of irreproducibility with lyophilized peptides is not the sequence itself but the arithmetic around it. A 15 mg vial contains a nominal peptide mass; the actual peptide content of any lyophilized cake also reflects counter-ion and residual moisture content, so laboratories reporting exact molar concentrations should either use the net peptide content figure from the lot certificate or determine content independently by amino acid analysis or quantitative UV. Using the published average mass of 418.4 g/mol, a full 15 mg vial reconstituted in 1 mL of diluent gives a convenient round stock concentration for serial dilution.

Three practical points recur in method sections for this class of material:

Vehicle matters. Record the diluent, its preservative content and its pH alongside the concentration. Bacteriostatic and sterile water are not interchangeable in every assay, and benzyl alcohol can interfere with sensitive cell based readouts.
Adsorption is real. At low working concentrations, peptides adsorb to polypropylene and glass. Low-bind labware or a carrier protein in the dilution buffer keeps the delivered concentration close to the nominal one.
Cite the lot. Because purity, counter-ion and net content vary between syntheses, methods sections should name the supplier lot for Pinealon so a later replication can be matched to the same analytical record.

Where a study spans several weeks, aliquoting the reconstituted stock immediately and freezing single-use volumes avoids the freeze-thaw cycling that accounts for most of the potency drift observed in longitudinal work.

Choosing the right presentation

Pinealon is released at 10 mg, 15 mg. Larger presentations lower the cost per milligram but commit a laboratory to using or storing more reconstituted material; smaller vials suit pilot work, method development and screening plates where a single stock is consumed quickly. The 15 mg vial listed on this page is priced at $54.00. Whatever presentation you select, the underlying material comes from the same synthesis and release programme, so switching strength does not change the analytical profile.

Orders ship from our facility in Chase City, Virginia, within the United States only, and every shipment carries the research use restriction on the outer documentation. Vials travel at ambient temperature in a rigid insert; lyophilized peptide is stable for the transit window, and the material should be moved to its long term storage temperature on arrival. Research materials are non returnable once dispatched.

Quality programme and laboratory support

Every Pinealon release passes through the same programme: synthesis against a defined sequence, in-house RP-HPLC purity assay, independent third party HPLC and mass spectrometry confirmation, visual inspection of the lyophilized cake, and a documented fill and seal step under inert gas in USP Type I borosilicate glass. Material that fails any stage is not released, and the certificate published for a lot is the certificate generated for that specific synthesis – never a representative or historical document carried over from an earlier batch.

Laboratories evaluating Pinealon for the first time frequently ask for the raw analytical files rather than the summary certificate. Chromatograms, mass spectra and, where applicable, net peptide content data can be requested for any lot; our support team answers analytical questions directly rather than through a ticket queue. Institutional purchasing, repeat supply for multi-month studies and quotations for multiple strengths are handled the same way.

Terminology used on this page

Lyophilized: Freeze dried under vacuum. Removing water as vapour rather than liquid leaves a porous cake that dissolves quickly and is far more stable in storage than a peptide held in solution, which is why Pinealon is supplied this way rather than pre-reconstituted.
RP-HPLC purity: Reverse-phase high performance liquid chromatography separates the target sequence from synthesis-related impurities by hydrophobicity. The reported figure is the target peak area as a percentage of total integrated peak area; it is measured per lot and published on that lot’s certificate of analysis, against a release specification of ≥ 98%.
Mass spectrometry confirmation: An orthogonal identity check. Purity alone cannot distinguish the correct sequence from a co-eluting analogue of similar hydrophobicity; measuring the molecular ion against the expected 418.4 g/mol confirms that the peak being integrated is the intended molecule.
Net peptide content: The fraction of the vial mass that is peptide rather than counter-ion or residual water. It is the figure to use when converting a 15 mg fill into an exact molar stock concentration.
Research use only: The material is sold for in vitro and laboratory investigation by qualified personnel. It is not a medicine, supplement, food or cosmetic, carries no approval for human or veterinary administration, and must be handled under the purchasing institution’s own safety procedures.
