Overview
Selank is a synthetic heptapeptide analog of the immunomodulatory tetrapeptide tuftsin, extended with Pro-Gly-Pro for peptidase resistance. It is used as a reference standard in anxiolytic, GABAergic and neuroimmune signaling research.
Mechanism
Published work describes modulation of GABA-A receptor expression and of enkephalin-degrading enzyme activity, stabilising endogenous enkephalin levels. Its tuftsin backbone also gives it documented effects on interleukin expression, linking the anxiolytic and immune literature.
Research applications
- GABA-A receptor expression and binding assays
- Enkephalin degradation and stability studies
- Anxiolytic behavioural models
- Interleukin (IL-6, IL-1beta) expression panels
- Serotonin and monoamine metabolism research
Reconstitution
Allow vial to reach room temperature before opening (at least 20 minutes). Reconstitute with 1.0 to 2.5 mL of sterile bacteriostatic water (0.9% benzyl alcohol). Inject solvent slowly down the inner wall of the vial; do not direct the stream onto the lyophilized cake. Swirl gently for 30 seconds. Do not vortex. Allow to dissolve for 5 minutes; clarity should be complete with no visible particulates.
Storage & handling
Reconstituted solution is stable for 28 days at 2 to 8 C in the original vial. For longer storage, aliquot into low-binding tubes and hold at -80 C; avoid repeated freeze-thaw cycles. Discard if turbidity, color change, or particulate matter is observed.

Selank questions
- What is Selank?
- Selank is a synthetic heptapeptide analog of the immunomodulatory tetrapeptide tuftsin, extended with Pro-Gly-Pro for peptidase resistance. It is supplied as a lyophilized research reference standard.
- What purity is Selank, and is there a COA?
- Every lot of Selank is independently verified by Janoshik (reverse-phase HPLC for purity, mass spec for identity) to a ≥99% purity floor. The lot-specific Certificate of Analysis is tied to the number on the vial label and available on request.
- How is Selank shipped in Canada?
- Selank ships domestically across Canada, dispatched within 24-48 hours via Canada Post Xpresspost and arriving in about four days. No border to cross, no customs. Flat $25 CAD shipping, free over $200.
- How do I reconstitute Selank?
- Allow vial to reach room temperature before opening (at least 20 minutes). Reconstitute with 1.0 to 2.5 mL of sterile bacteriostatic water (0.9% benzyl alcohol). Inject solvent slowly down the inner wall of the vial; do not direct the stream onto the lyophilized cake. Swirl gently for 30 seconds. Do not vortex. Allow to dissolve for 5 minutes; clarity should be complete with no visible particulates.
- How should Selank be stored?
- Reconstituted solution is stable for 28 days at 2 to 8 C in the original vial. For longer storage, aliquot into low-binding tubes and hold at -80 C; avoid repeated freeze-thaw cycles. Discard if turbidity, color change, or particulate matter is observed.
- Is Selank legal to buy in Canada?
- Selank is sold as a laboratory research reference standard, for laboratory research use only. It is legal to sell for that purpose and is not approved by Health Canada as a drug.
