DIDS (sodium salt)

DIDS is a stilbene sulfonate that inhibits anionic transport. It has been used to inhibit Cl- uptake through plasma membrane-localized Cl- channels in order to study chloride transport. It also effectively inhibits various sodium-coupled bicarbonate transporters.Formal Name: 2,2'-(1,2-ethenediyl)bis[5-isothiocyanato-benzenesulfonic acid], disodium salt. CAS Number: 67483-13-0.
