How to Store Selank: Temperature, Shelf Life & Handling

Storage requirements for Selank follow from what the molecule actually is — synthetic heptapeptide, tuftsin analogue. The conditions below reflect that chemistry rather than generic peptide guidance.

Synthetic heptapeptide, tuftsin analogueCognitive & Neurological

In plain English

Freezer for the powder, fridge once mixed, and it holds up for three to four weeks — a longer window than most molecules its size. The reason is simple: it contains none of the amino acids that react with light or oxygen, so those clocks never start.

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.

Storage conditions for Selank

Lyophilized powderSealed at -20 °C for long-term storage; short 2–8 °C periods are acceptable.
ReconstitutedRefrigerate at 2–8 °C. Selank contains no methionine, cysteine, or tryptophan, so it is notably less oxidation-sensitive than Semax.
Working windowCommonly worked with for 3–4 weeks at 2–8 °C — a longer window than most peptides of comparable size, precisely because it lacks oxidisable residues.

Why these conditions, specifically

Selank is chemically one of the more forgiving peptides here. Its handling risk is physical loss to surfaces rather than molecular breakdown, which means the countermeasure is low-bind labware rather than light protection.

The main route to be aware of: adsorption to glass and untreated plastic — the practically significant loss route for this cationic peptide at low concentration, not a chemical degradation at all.

All 3 degradation routes for Selank

Freeze–thaw

Tolerant, but aliquoting is still the correct default for a multi-week study.

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.
