About the compound
What is Selank?
Selank is a synthetic peptide analogue of tuftsin, a naturally occurring immunomodulatory tetrapeptide. It is assigned CAS number 129954-34-3 and has a molecular weight of 751.87. The synthetic sequence extends the tuftsin fragment to improve its stability as a research molecule. In a laboratory catalogue Selank is classed within the nootropic research category. Selank UK material is supplied strictly for laboratory research use only.
As a tuftsin analogue, Selank is studied for its interaction with immune-signalling and neuropeptide pathways. Research has examined its association with the regulation of certain cytokines and with the expression of BDNF, as well as its influence on monoaminergic and GABAergic signalling in experimental models. These mechanistic observations are drawn from animal and cell-based studies that characterise biochemical responses under controlled conditions.
Selank is investigated in anxiolytic and nootropic research, where behavioural and biochemical models are used to characterise its activity in the laboratory. It is commonly paired with Semax in comparative studies, since both are short synthetic peptides developed in Russia and examined within similar research programmes. This body of work sits entirely within experimental contexts and describes findings in research systems only.
Sova supplies Selank as a lyophilised powder for use in controlled laboratory environments. Every batch is characterised by reverse-phase HPLC and electrospray-ionisation mass spectrometry, and the results are recorded on a batch-linked Certificate of Analysis. The material is sourced and held in the United Kingdom to give research customers dependable access. This material is sold strictly for laboratory research use only.

FAQ
Selank, answered.
What is Selank?
+
Selank is a synthetic peptide analogue of tuftsin, a naturally occurring immunomodulatory tetrapeptide (CAS 129954-34-3, molecular weight 751.87). The sequence is extended for greater stability and is used as a reference compound in neuroscience and immunology-focused research.
Is Selank legal to buy in the UK?
+
In the UK, Selank is supplied as a research chemical for laboratory research use only. It is not an authorised medicine and must not be marketed or used for human purposes. On that basis it may be purchased by researchers and institutions.
What is Selank studied for?
+
Selank is investigated in anxiolytic and nootropic research using behavioural and biochemical models. Studies have examined its association with cytokine regulation, BDNF expression and monoaminergic and GABAergic signalling, with all observations drawn from controlled laboratory systems.
How is Sova's Selank verified?
+
Each batch of Sova's Selank is analysed by reverse-phase HPLC to check identity and composition and by electrospray-ionisation mass spectrometry to confirm molecular mass. Results are recorded on a batch-linked Certificate of Analysis supplied with the material.
How should Selank be stored?
+
Selank is best stored as a lyophilised powder in a sealed, light-protected container under cold conditions, with a freezer suited to longer-term storage. Once reconstituted, solutions are typically kept refrigerated and used within a short window.
What is tuftsin, the peptide Selank is based on?
+
Tuftsin is a naturally occurring tetrapeptide with immunomodulatory properties. Selank is a synthetic analogue built on this sequence with modifications that improve stability, making it a useful research tool for studying tuftsin-related and neuropeptide pathways in the laboratory.
