Application

Bis(dimethylamino)-dimethyl silane was used to silanize pH-sensitive microelectrodes, used to measure the membrane potential in oocytes, in an experimental procedure aimed towards cloning and characterising human electrogenic Na+-cotransporter isoform (hhNBC). It was also used for microelectrode measurements, in a study conducted to measure carbon dioxide transport through membranes.
