Physical Properties
Selank is a synthetic heptapeptide derived from the endogenous immunomodulatory peptide tuftsin. Its short chain length supports efficient aqueous solubility and practical laboratory handling. As a linear peptide, it remains susceptible to enzymatic degradation in biological environments, making lyophilized storage under cold, dry conditions important for maintaining stability. Protection from moisture, light exposure, and repeated freeze–thaw cycles helps preserve structural integrity and analytical consistency during research applications.

How is Selank supplied?
Selank is typically supplied as a lyophilized (freeze-dried) powder in sealed research vials to preserve stability during storage and shipment.
How should unreconstituted Selank be stored?
Lyophilized Selank should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
How should reconstituted Selank be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
