Selank Peptide: What In-Vitro Research Shows
Selank (TKPRPGP), a synthetic tuftsin analogue: its GABA and BDNF research profile in preclinical models. In-vitro laboratory research framing only.
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro, TKPRPGP) developed as a stabilised analogue of the endogenous immunopeptide tuftsin. It is studied in the laboratory as a water-soluble research peptide.
Structure and identity
Selank adds a proline-rich extension to the tuftsin core, which improves its stability in solution relative to the parent peptide. It is supplied as a lyophilised powder for reconstitution under laboratory conditions.
What the research literature examines
Preclinical and in-vitro studies have examined Selank in the context of GABA-ergic signalling, BDNF expression and monoamine pathways in model systems. This research is exploratory and conducted in laboratory and animal models. Vivera Labs makes no claims regarding effects in humans; the compound is supplied strictly for in-vitro laboratory research.
Why purity matters for this peptide
Receptor- and expression-level assays are sensitive to impurities. Independent third-party HPLC analysis and a batch-specific Certificate of Analysis help ensure the peptide in the vial matches the intended sequence.
- Identity confirmed by mass spectrometry
- Purity quantified by HPLC
- Batch-specific documentation
- Lyophilised for stability

It is studied in the laboratory as a water-soluble research peptide and supplied as a lyophilised powder for reconstitution under laboratory conditions.
What does Selank research examine?
Preclinical and in-vitro studies have examined Selank in the context of GABA-ergic signalling, BDNF expression and monoamine pathways in model systems. This research is exploratory and conducted in laboratory and animal models. Vivera Labs makes no claims regarding effects in humans; the compound is supplied strictly for in-vitro laboratory research.
How is Selank different from tuftsin?
Selank adds a proline-rich extension to the tuftsin core, which improves its stability in solution relative to the parent peptide. It is supplied as a lyophilised powder for stability.
Why does purity matter for Selank research?
Receptor- and expression-level assays are sensitive to impurities, so independent third-party HPLC analysis and a batch-specific Certificate of Analysis help ensure the peptide in the vial matches the intended sequence. Identity is confirmed by mass spectrometry and purity is quantified by HPLC, with batch-specific documentation.
