Selank is synthesized using solid-phase peptide synthesis (SPPS), followed by HPLC purification. Lyophilization enhances shelf life and transport stability.
Storage recommendations:
Lyophilized powder: Store at −20 °C, protected from light and moisture.
Reconstituted solution: Store aliquots at −80 °C; avoid repeated freeze-thaw cycles.
A reliable Selank supplier should provide:
Certificate of Analysis (CoA)
HPLC chromatogram and MS data
Batch number and synthesis date
Statement of research-use-only compliance
Selank’s structure confers exceptional stability and resistance to enzymatic degradation, making it well suited for long-term in-vitro studies and neuropeptide modeling.
Selank’s mechanisms and neuroactive properties make it relevant to multiple research domains:
Selank is studied for its influence on GABAergic and serotonergic pathways, key targets in anxiety and mood research.
