Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    BT474 and MDA-MB-361 tumor cell lines

  • Concentrations

    0-15 μM

  • Incubation Time

    72 h

  • Method

    Cell viability is measured by Cell Titer Glo assay after 72 hours of treatment with vehicle or drugs. For all experiments with fulvestrant, cells are grown in estrogen free conditions, and estradiol is added to a final concentration of 10-8 M prior to drug treatment.
