Description

Selank is a synthetic heptapeptide and analogue of the naturally occurring peptide tuftsin. It has been investigated in experimental research involving peptide signaling, receptor interactions, and neurobiological mechanisms.

This research material is supplied as a lyophilized powder for laboratory research, analytical testing, and related scientific applications.

The specifications above correspond to the Selank free-peptide form documented by PubChem. Selank diacetate is a separate salt form with a different molecular formula and molecular weight, so the batch documentation should be used to confirm the exact chemical form when applicable.

Research & Scientific Context

Selank was developed as a synthetic analogue of tuftsin, a naturally occurring tetrapeptide. Unlike tuftsin, Selank is a seven-residue peptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro.

Research has examined Selank using biochemical, receptor-binding, and animal models. A published review discusses its interaction with GABA-related signaling, while experimental studies have examined its effects in specific rodent models. These findings are preclinical and should not be interpreted as established clinical effects.

Selank and Tuftsin

Selank is structurally related to tuftsin but is not the same peptide. Tuftsin is a naturally occurring tetrapeptide, whereas Selank contains seven amino-acid residues and has its own defined sequence and molecular structure.

Analytical Documentation

A Certificate of Analysis (COA) is included in the product image gallery. Researchers should review the batch-specific documentation to confirm reported purity and other available analytical characteristics.

The exact chemical form should also be confirmed from the applicable documentation, particularly when distinguishing the free peptide from salt forms such as Selank diacetate.

Frequently Asked Questions

1. What type of peptide is Selank?

Selank is a synthetic heptapeptide, meaning it contains seven amino-acid residues. Its sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro.

2. Is Selank derived from tuftsin?

Selank was developed as an analogue of tuftsin. It shares the Thr-Lys-Pro-Arg-Pro portion of the sequence but contains additional residues that give Selank its distinct seven-residue structure.

3. What is the molecular weight of Selank?

PubChem reports a molecular weight of approximately 751.9 g/mol for the Selank free peptide. Salt forms can have different molecular weights.

4. What is the CAS number for Selank?

The CAS number associated with the Selank free peptide is 129954-34-3.

5. What has Selank been studied for?

Published research has examined Selank in areas including peptide signaling, GABA-related mechanisms, and experimental neurobiological models. Some studies have used rodents, so these findings should be distinguished from established human clinical evidence.

6. How should the Selank COA be used?

The batch-specific COA can be used to review the reported purity and analytical information for the material. Researchers should confirm the chemical form and applicable specifications against the documentation supplied with the individual batch.
