Objective:
To introduce a rapid colorimetric method for assessing the viability of osteosarcoma cells after chemotherapy.
Methods:
Colorimetric assay and automatic microplate scanning spectrophotometer were used for assaying the viability of osteosarcoma cells.
Results:
Close correlation was found between the absorbance at 570 nm of the formazan products and the number of viable osteosarcoma cells.
Conclusion:
An effective, sensitive and convenient colorimetric assay has been established to assess the survival of osteosarcoma cells following chemotherapy.
