AMPA Receptor |
NASPM selectively suppresses the inwardly rectifying and Ca2+-permeable AMPA receptors expressed in type II neurons. It has no effect on AMPA receptors in type I neurons. At -60 mV, NASPM suppresses AMPA receptors in type II neurons with an IC50 value of 0.33 μM. The blocking effect of NASPM on the Ca2+-permeable AMPA receptors is use and voltage-dependent[1].

Solvent & Solubility
H2O : 50 mg/mL (104.19 mM; Need ultrasonic)
DMSO : 6.4 mg/mL (13.34 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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.
