6-甲氧基-N-乙基喹啉碘化物

MEQ是细胞膜不可渗透的氯化物指示剂。可将其还原以产生可透过细胞的二氢-MEQ（DiH-MEQ），可将其被动加载到细胞中，然后氧化为对氯敏感的MEQ。用于监测脑片中氯化物的变化并测量GABA受体的活性。

MEQ is a cell membrane impermeable chloride indicator. It can be reduced to create the cell-permeant dihydro-MEQ (DiH-MEQ) which can be passively loaded into cells and subsequently oxidized to the chloride-sensitive MEQ. Used to monitor changes in chloride in brain slices and measure GABA receptor activity.
