Lipoic acid is a selective, small molecule large-conductance Ca(2+)-activated K(+) channel (BKCa, KCa1.1, MaxiK) positive modulator with EC50 of 11 uM. Lipoic acid shows a favorable selectivity profile on Nav, Cav, SK, and IK channels. Lipoic acid causes distinct activation from a concentration of 0.3 and 10 µM Lipoic acid left-shifted the voltage activation curve by 60 mV. Lipoic acid reduces spontaneous phasic contractions in guinea pig urinary bladder strips at 1 uM, while having only a modest effect on contractions evoked by electrical field stimulation (EFS) and no effect on high K+-induced contractions.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
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.
