Spadin
Based on 1 publication(s) in Google Scholar
Spadin, a natural peptide derived from a propeptide released in blood, is a potent TREK-1 channel blocker with IC50 value of 10 nM. Spadin enhances dorsal raphe nucleus 5-HT neurotransmission in mice and induces hippocampal CREB activation and neurogenesis. Spadin can be used for antidepressant research.

Biological Activity
Spadin (100 nM; COS-7 cells) has inhibitory effect of spadin on the TREK-1 channel and blocks 63% of the TREK-1 current stimulated by arachidonic acid[1].
Spadin (100 nM) blocks the TREK-1 channels activity in CA3 hippocampal neurons on brain slices of wild-type mice[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Spadin (0.01-100 μM; ICV, i.p. and i.v.; daily, for 7 days; male C57Bl/6J and TREK-1 deficient mice) has anti-depressant behavior in mice[2].

Solvent & Solubility
H2O : ≥ 100 mg/mL (49.69 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
