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.

Is Selank naturally occurring?
No. Selank is a synthetically engineered peptide, although it is structurally derived from tuftsin-related research. It does not occur naturally in this exact form.
How does Selank differ from Semax?
Selank and Semax are structurally distinct peptides studied in neuropeptide research. Selank is commonly investigated for GABAergic and immune-related signaling models, while Semax is more often studied for neurotrophic factor and monoaminergic pathway interactions.
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
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Gently swirl to mix; avoid vigorous agitation
Does Selank require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, verifying peptide identity, purity, and analytical testing results to ensure research quality and traceability.
Is Selank FDA-approved?
No. Selank is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
