What Is Selank?
Selank is a seven-amino-acid peptide made by adding a Pro-Gly-Pro tail to tuftsin (Thr-Lys-Pro-Arg), a naturally occurring fragment of immunoglobulin G. The tail stabilises the peptide against enzymatic cleavage. Our Selank 10mg vial contains the sequence TKPRPGP, with a molecular weight of approximately 751.9 Da.
Selank was developed at the Institute of Molecular Genetics in Moscow and has been studied as a neuropeptide tool compound for several decades. The lyophilised format keeps the peptide stable in storage; researchers who need a ready-made solution can choose our Semax + Selank nasal spray.
Selank Research Areas
Laboratory studies of Selank cover the following areas of the published literature:
GABAergic Signalling
Selank is studied for its modulation of GABA-A receptor function and its interaction with benzodiazepine-site pharmacology in neuronal preparations. Published work can be explored on PubMed.
Anxiety-Related Behavioural Models
Preclinical behavioural research uses Selank in standard anxiety and stress-response paradigms.
Immune Signalling
As a tuftsin analogue, Selank is investigated for its effects on cytokine expression, interleukin balance and innate immune signalling in cell models.
Enkephalin Degradation
Selank has been examined for its inhibition of enkephalin-degrading enzymes, a mechanism relevant to its behavioural effects.
Selank vs Semax
Selank and Semax share the stabilising Pro-Gly-Pro tail but derive from different parent molecules: Selank from tuftsin, Semax from ACTH. Selank is primarily studied in anxiety-related and immune-signalling models; Semax in neurotrophin and neuroprotection models. Many laboratories study the two side by side.
