What Does Selank Dissolve In? Solvents Explained

Solubility behaviour is where compounds in this library differ most sharply from one another. For Selank, the determining factors are structural: synthetic heptapeptide, tuftsin analogue.

Synthetic heptapeptide, tuftsin analogueCognitive & Neurological

In plain English

Very water-friendly, thanks to a strong positive electrical charge. That same charge is a double-edged thing — it makes the molecule dissolve readily but also makes it cling to container walls, which quietly removes material from weak solutions.

What Selank actually is

Selank came out of the same Moscow programme as Semax, built from tuftsin — a tiny natural fragment released from antibodies — with the same stabilising tail added. Its research literature centres on anxiety-related behaviour and the brain signalling systems associated with it.

Supplied for laboratory research use only — not for human or animal use.

Research-grade Selank

Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

How Selank behaves in solution

Freely water-soluble. Two basic residues (Lys, Arg) give the molecule a strong net positive charge at neutral pH, which drives high aqueous solubility but also makes it the most adsorption-prone short peptide in this catalogue at dilute concentrations.

Structural basis

Selank is synthetic heptapeptide, tuftsin analogue. Selank was developed at the Institute of Molecular Genetics in Moscow by extending the immunomodulatory tetrapeptide tuftsin (Thr-Lys-Pro-Arg) with the same Pro-Gly-Pro stabilising motif used in Semax. It is, in effect, the anxiolytic-research counterpart to Semax from the same design programme.

What Selank is studied for

Anxiolytic models

The most-populated area of the Selank literature, examined in behavioural anxiety models.

GABAergic and serotonergic modulation

Studies have investigated interaction with both systems without the sedative profile of classical anxiolytics.

Tuftsin lineage and immune signalling

Its parent tetrapeptide is immunomodulatory, and some research follows that thread.

Memory consolidation

Investigated in learning and memory paradigms alongside its stress-response work.
