GoSlo-SR-5-69 is a potent high-conductance calcium-activated potassium channel (BK channel) agonist, with an EC50 of 251 nM. GoSlo-SR-5-69 significantly shifts the voltage required for half-maximal activation in a negative direction (ΔV1/2 = −104 mV), thereby enhancing channel open probability. Widely used in studies of neuronal excitability, vasodilation, smooth muscle regulation, and ion channel pharmacology, it elucidates BK channel function under physiological and pathological conditions.

DMSO
| |||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
