Flow cytometry assessment of cell viability in 3D cell cultures
Flow cytometry provides a versatile assay for analyzing proportions of different cell populations within dissociated spheroid cultures. At Biotect Services, we provide a validated flow cytometry-based assessment of the percentage of live cells in spheroids derived from tumor cell lines treated with drugs of interest. This assay can be used to evaluate drug susceptibility of tumor spheroids and to benchmark against control treatments.
Spheroids are seeded 5,000 cells / well in ultralow attachment plates and treated with Staurosporine. Spheroids are then dissociated and stained with viability dye for flow cytometry analysis to quantify the proportion of live cells. Dose-response curves from two independent experiments are shown for U251 spheroids treated with Staurosporine.
