Protocol

Cell experiment [1,2]:

Cell lines

Rat dorsal root ganglion neurons, bladder

Preparation method

Soluble to 0.70 mg/ml in sterile water. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

10-100 nM

Applications

Iberiotoxin (IbTX) (10-100 nM) increased the myogenic activity of bladder, but not portal vein. IbTX caused a sustained contracture of aorta. In rat dorsal root ganglion neurons, IbTx (100 nM) reduced whole-cell outward currents in 67% of small and medium size neurons. IbTx significantly prolonged the duration of action potential and increased firing frequency of afferent neurons.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
