Overview
This is Selank supplied as a ready-made solution rather than a lyophilized powder: 10 mg of peptide in 10 mL (1 mg/mL), filled into a metered spray bottle that delivers 100 mcg per actuation, about 100 actuations per bottle. The peptide is the same heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) as the 10mg vial in this catalog. Supplied for laboratory research use only; not for human or veterinary use.
In experimental systems, Selank has been investigated for its interactions with GABAergic, serotonergic, dopaminergic, and enkephalin-related signaling, as well as its reported modulation of brain-derived neurotrophic factor expression. It serves as a reference tool compound in research examining anxiolytic mechanisms, nootropic activity, and neuro-immune crosstalk. This material is supplied strictly for in vitro and laboratory research applications and is not intended for human or veterinary use.
Research areas
- Anxiolytic mechanism studies
- Cognitive and nootropic models
- GABAergic neurotransmission research
- Serotonergic signaling pathways
- Neuro-immunomodulation studies
- Peptide stability and metabolism
