Biological Activity

DIDS is a ClC-Ka chloride channel blocker (IC50 = 100 μM). Blocks the maxi chloride channel in apical membranes from human placenta. Displays antagonistic activity at TRPM4 and TRPC4 channels; potentiates agonist-induced TRPV1 currents (IC50 = 4.88 μM in rat DRG neurons). Inhibits RAD51 recombinase activity (KD = 2 μM).

Technical Data

Soluble to 5 mM in Potassium bicarbonate (0.1M)
Store at +4°C
