Pinealon (Bioregulator) from Xcel Peptides

Xcel Peptides supplies Pinealon as a lyophilized bioregulator peptide for laboratory use. We test every batch independently before release, and we publish the certificate of analysis on this page, matched to the batch number on your vial.

What Is Pinealon

Pinealon is a synthetic tripeptide made of three amino acids: glutamic acid, aspartic acid, and arginine (Glu-Asp-Arg, or EDR). Its molecular weight is about 418.4 g/mol, and its CAS number is 175175-23-2. It belongs to the short-peptide bioregulators developed by Vladimir Khavinson and colleagues in Russia. Researchers first characterized the EDR sequence from Cortexin, a polypeptide preparation derived from bovine cerebral cortex.

Specifications

The product is a lyophilized powder at research grade. We verify every batch through third-party HPLC and identity analysis, and we document it with a matched COA. Store the powder frozen and protect it from light. We ship every order cold-chain with tracking.

Research Applications

Researchers study Pinealon in cellular stress and gene expression research. Typical work examines how the EDR sequence affects free radical levels and cell viability in cultured neuronal cells, and how short peptides interact with DNA and chromatin-associated proteins in cell-based models. Scientists also use it as a reference peptide when comparing Khavinson-class bioregulators.

These describe research applications, not therapeutic claims. The FDA has not evaluated this product, and researchers should not use it to diagnose, treat, cure, or prevent any condition.

Why Buy Pinealon From Xcel Peptides

Short peptides look alike on paper, and suppliers sometimes confuse one bioregulator with another. Xcel Peptides lists the exact sequence and CAS number for Pinealon and tests each batch to confirm identity, so your records match the material you receive.

We also publish our results openly. You can match the batch number on your vial to the COA before you start work, instead of relying on a generic purity claim.

Storage and Handling

Store the lyophilized vial frozen and protected from light before reconstitution. Once reconstituted, refrigerate the solution and use it within a short window, since peptide stability drops considerably outside the dry state. Avoid repeated freeze-thaw cycles, since each cycle degrades the peptide structure further.

Verifying Your COA

Check three things on the COA before you use this product. First, confirm the batch number matches your vial. Second, confirm the test date is recent. Third, confirm the HPLC purity and the identity result match the EDR sequence and the 418.4 g/mol mass for your size. If you need archived data for a previous lot, contact our team and we’ll pull it for you.

Frequently Asked Questions

What is Pinealon? It’s a synthetic tripeptide (Glu-Asp-Arg, or EDR) from the Khavinson family of short-peptide bioregulators. Xcel Peptides supplies it as a research-grade lyophilized peptide.

Is Pinealon the same as Epitalon? No. Pinealon is the tripeptide EDR, while Epitalon is the tetrapeptide AEDG. The names are similar because both relate to pineal research, but they are different compounds.

What is a bioregulator peptide? It’s a short peptide, usually two to four amino acids, designed to match a fraction isolated from a specific tissue. Researchers study how these peptides affect gene expression in cell models.

Does Pinealon come with a COA? Yes. Xcel Peptides ships every vial with a batch-matched certificate of analysis confirming identity and purity.

How should I store Pinealon? Store the lyophilized powder frozen and protected from light. After reconstitution, refrigerate the solution and avoid repeated freeze-thaw cycles.

How fast does Xcel Peptides ship this product? We ship most orders within 1 to 2 business days, with cold-chain packaging and tracking included.
