Assay Method Information

Assay Name:  Lactate Transport in MCT4-Expressing MDA-MB-453 Breast Cancer Cells
Description:  MCT4 may be stably expressed in MDA-MB-453 breast cancer cells that do not express native MCT1 or MCT4. MCT4 activity may be assessed by monitoring the intracellular pH change that accompanies lactate/proton symport, using the pH-sensitive fluorescent dye 2',7'-bis-(carboxyethyl)-5(6)-carboxyfluorescein (BCECF), in a manner similar to that previously reported for MCT1 and MCT4. The following is an exemplary procedure for assaying MCT4 activity of the compounds of Formula (I).
