T47D-182R2 Cell Line

T47D-182R2 is an adherent human breast cancer cell line that exhibits resistance to fulvestrant (Faslodex). It was developed from the parental T47D/S5 cell line through long-term exposure to 100 nM fulvestrant.

Product description: T47D-182R2 is an adherent human breast cancer cell line that exhibits resistance to fulvestrant (Faslodex). It was developed from the parental T47D/S5 cell line through long-term exposure to 100 nM fulvestrant. The cells retain an epithelial morphology. As resistance to fulvestrant—a common second-line endocrine therapy—is a clinical challenge, T47D-182R2 represents a valuable model for studying acquired resistance mechanisms. It serves as a robust tool for identifying targeted therapies against resistant tumor cells, as well as for evaluating strategies to prevent or delay resistance emergence.
Production details: Human breast cancer cell line derived from T47D/S5 by long term treatment with 100 nM fulvestrant.
Cellosaurus ID: CVCL_1D35
Parental cell line: T47D/S5
disease: Cancer
Format: Frozen
Shipping conditions: Dry ice
Growth medium: Phenol red free RPMI 1640 + 5% FCS + glutamax + 8ug Insulin/ml + 100 nM fulvestrant. Fetal Calf Serum (FCS) typically contains less estrogen than Fetal Bovine Serum (FBS) and is the preferred supplement for this cell line.
Subculture routine: Following thawing and counting, dilute the cell suspension with sufficient medium and distribute 5 mL each into T25 flasks to achieve a seeding density of 1.8 – 2.0 x 10^4 / cm2. Place in 37°C, 5% CO₂ incubator. Change medium after 24 hours to remove residual DMSO and then every 2-3 days. Subculture routine: Split 1:7 weekly (slow growing cell line) with Trypsin-EDTA for detachment at 37 °C for 5 minutes. Please also see detailed protocol within the Product Datasheet in the Documentation section below.
Temperature: 37°C
Atmosphere: 5% CO₂
Storage medium: 10% DMSO in FCS
