Biological descriptionFirst selective small conductance Ca2+-activated K+ channel (SK) activator. Selectively opens SK2 and SK3 channels (EC50 values are 5.6 and 14 μM, respectively). Shows no activity at SK1 and IK. Additionally reduces activity and excitability of dopamine neurons. Active in vivo.
Storage instructionsStore at +4°C. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 100 mM and in ethanol to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
