Development of a media cell-free DNA direct digital PCR method for cell viability estimation

Accurate estimation of cell viability is crucial in various applications such as cytotoxicity testing and routine cell culture on both industrial and laboratory scales. For this, the real-time monitoring of cell status would be beneficial. Conventional cell-based assays for cell viability have limitations in sensitivity and time-effectiveness. Analysis of cell-free DNA (cfDNA) in (culture) media is a good alternative as cfDNA release are a well-known phenomenon during cell death.
