Cell Assay
[1][2]

Phenol red is dissolved in 0.1% ethanol. To determine the effect of phenol red on cell proliferation, MCF-7 cells grown for 1 week before experiments in phenol red-free MEM supplemented are harvested and seeded into T-25 flasks (ca. 1.5 x 105 cells per flask). The following day, cells from three flasks are harvested and counted with a Coulter Counter. Then the medium is changed to phenol red- and insulin-free MEM, which contains various concentrations of dextran-coated charcoal-treated calf serum, phenol red (0-300 μM), tamoxifen, hydroxytamoxifen, estradiol, or ethanol vehicle (0.1%), and cell number is monitored as a function of time[1]. Phenol Red sodium salt is dissolved in distilled water as a 10 g/L stock solution[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
