General description

T47D/TR-1 cells are ER alpha positive and express progesterone receptor, although at reduced level compared to parental T7D/S2 cells. T47D/TR-1 cells are growth inhibited by fulvestrant. Oestrogen receptor.

Cell Line Description

The T47D/TR-1 is a breast cancer cell line resistant to tamoxifen. The T47D/TR-1 cell line has been established by long term treatment of T47D/S2 cells with 1 μM tamoxifen. Clonal selection was performed in medium without tamoxifen. After growth in presence of 1 μM tamoxifen for 10 months, the growth rate was similar to the parental cells.

Subculture Routine

Split sub-confluent cultures (70-80%) 1:3 to 1:6 i.e. seeding at 2-4 x 10, 000 cells/cm² using 0.05% trypsin/EDTA; 5% CO2; 37°C. Recommend media changes every 2-3 days.
