Monitoring live cell viability: Comparative study of fluorescence, oblique incidence reflection and phase contrast microscopy imaging techniques.
The relative performances of fluorescence, oblique incidence reflection and phase contrast imaging techniques have been studied for the purpose of monitoring long-term cellular activity and cell viability of several types of normal and cancerous cells in cultures. Time-lapse movies of live cell imaging of untagged and green fluorescent protein (GFP) tagged cell lines are presented. Oblique incidence reflection microscopy is the simplest and least expensive method to implement, appears to be the least phototoxic to cells, and is recommended for use in long-term optical monitoring of cell viability.
