High-purity Pinealon (Glu-Asp-Arg) is available for procurement through accredited research suppliers such as PX1 Research. Intended strictly for in vitro assays and animal models, research-grade Pinealon requires HPLC/MS verification, endotoxin testing below strict analytical thresholds, and transparent lot-specific COAs to guarantee absolute batch-to-batch consistency in controlled laboratory settings.
When evaluating options to buy Pinealon for institutional or laboratory projects, establishing verified compound identity and purity is the primary prerequisite. Synthetic short peptides require precise solid-phase peptide synthesis (SPPS) protocols to prevent truncated impurities or racemic modifications that could introduce confounding variables into gene expression or oxidative stress assays. PX1 Research fulfills these requirements by providing verified reference standards supported by third-party analytical testing for every manufactured batch.

Pinealon is a synthetic tripeptide consisting of L-glutamic acid, L-aspartic acid, and L-arginine, represented by the amino acid sequence Glu-Asp-Arg (EDR). With a chemical formula of C15H26N6O8 and a molecular weight of approximately 388.38 g/mol, Pinealon belongs to the class of short-chain peptide bioregulators initially identified during investigations into pineal gland tissue extracts.
Due to its short amino acid sequence and net negative charge at physiological pH, Pinealon exhibits high solubility in aqueous buffers. The presence of side-chain carboxyl groups from glutamic and aspartic acid alongside the basic guanidino group of arginine creates a distinct zwitterionic balance. This chemical architecture facilitates conformational stability in liquid solutions while allowing the tripeptide to easily penetrate cellular membranes in cell culture models.
Understanding these structural parameters is essential when designing protocols for cell culture supplementation or binding studies. Investigators interested in similar short-chain regulatory peptides can access detailed chemical specifications across our peptide research database to compare molecular attributes and solubility kinetics.
Preclinical studies suggest that Pinealon operates primarily through epigenetic mechanisms, specifically interacting with chromatin and nuclear histone complexes to modulate gene transcription. In vitro models utilizing neuronal primary cultures demonstrate that EDR tripeptides can cross nuclear membranes and bind to specific canonical sequences in double-stranded DNA, altering chromatin accessibility for RNA polymerase II.
In rodent models of age-related neurodegeneration and oxidative injury, administration of Pinealon has been observed to alter mRNA expression levels for key antioxidant enzymes, including superoxide dismutase (SOD1) and catalase. By modulating the transcription of genes associated with cellular survival and apoptosis, Pinealon demonstrates marked cytoprotective effects against hydrogen peroxide-induced necrosis and glutamate excitotoxicity.
Furthermore, preclinical evidence indicates that EDR interactions reduce hyperphosphorylation of tau proteins and inhibit the cascade of caspase-3 activation in stressed neural tissue. These molecular findings position Pinealon as a prominent research tool for studying epigenetic gene regulation, cellular aging mechanisms, and localized neuroprotection in vitro.
Within short-chain peptide research, Pinealon is frequently evaluated alongside other synthetic bioregulators and neuroactive agents. A comparative evaluation highlights key differences in sequence length, primary targets, and functional pathways in preclinical literature:
While Pinealon (Glu-Asp-Arg) focuses heavily on chromatin binding and localized neuronal mRNA transcription, Epithalon (Ala-Glu-Asp-Gly) is predominantly studied for its role in telomerase activation and pineal-hypophyseal endocrine regulation. In contrast, non-bioregulator peptides such as Semax target central neurotrophic factors like BDNF and NGF through distinct receptor-mediated pathways. Evaluating these complementary compounds side-by-side allows research groups to select the optimal peptide candidate based on specific cellular targets and experimental endpoints.
In vitro assays investigating central nervous system pathology heavily utilize Pinealon to model cell survival under induced oxidative stress. Primary cortical neurons and PC12 cell lines exposed to toxic concentrations of reactive oxygen species (ROS) exhibit significantly improved cell viability when co-incubated with EDR tripeptides.
Assays measuring mitochondrial membrane potential (MMP) indicate that Pinealon helps maintain the inner membrane gradient during metabolic insult, preventing the leakage of cytochrome c into the cytoplasm. Preclinical data further show a down-regulation of pro-inflammatory cytokines, including TNF-alpha and IL-1 beta, in microglial cell lines exposed to lipopolysaccharide (LPS) challenges after Pinealon treatment.
These cellular outcomes provide valuable insights into the biochemical cascades governing microglial activation, mitochondrial maintenance, and ROS neutralization, making Pinealon an indispensable reagent for neurobiology laboratories.
When procurement officers and principal investigators choose to buy Pinealon, verifying analytical purity is non-negotiable. Substandard synthesis can yield deletion sequences, residual coupling reagents, or heavy metal contaminants that invalidate experimental findings.
Every lot of Pinealon tripeptide supplied by PX1 Research undergoes strict dual-stage analytical testing. Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) verifies a chemical purity equal to or exceeding 98.0%, ensuring that chromatographic peaks representing peptide impurities are minimized. Concurrently, Electrospray Ionization Mass Spectrometry (ESI-MS) confirms the exact molecular mass (388.38 Da) to rule out sequence errors or incomplete deprotection.
Additionally, endotoxin testing via Limulus Amebocyte Lysate (LAL) assays guarantees endotoxin levels well below the industry standard threshold of <0.01 EU/mg. This level of purity ensures that cell culture models remain free from bacterial lipopolysaccharide contamination, preventing unwanted inflammatory signals during sensitive bioassays.
Proper handling and reconstitution protocols are vital to preserve the structural integrity of Pinealon prior to experimentation. As a lyophilized powder, Pinealon maintains high stability, but once dissolved in liquid media, correct handling techniques must be observed under sterile laminar flow hoods.
To reconstitute Pinealon for in vitro work, researchers typically utilize sterile bacteriostatic water or phosphate-buffered saline (PBS, pH 7.4). Gentle agitation should be applied to fully dissolve the cake; aggressive vortexing should be avoided to prevent shear stress on the peptide backbone. For stock solutions intended for long-term storage, aliquoting into sterile polypropylene tubes minimizes adsorption to container surfaces.
To review additional technical specifications on solvent compatibility, researchers can consult our comprehensive wholesale lab support resources or download batch-specific handling guides.
Lyophilized Pinealon should be stored at -20°C or -80°C in a desiccated environment to prevent moisture absorption and hydrolytic degradation. Under these frozen, desiccated conditions, the unconstituted peptide maintains chemical stability for up to 24 months.
Upon reconstitution, liquid aliquots should be kept at 2°C to 8°C if intended for immediate use within 7 to 14 days. For extended experimental timelines, reconstituted solutions must be stored at -20°C or below and protected from light. Repeated freeze-thaw cycles must be rigorously avoided, as temperature fluctuations cause physical degradation of peptide chains and precipitation out of solution.
