Here, we present a workflow that combines two technologies, cellenONE and QIAcuity Digital PCR, which accelerate and streamline high-throughput analyses of target copy numbers in cultured cells. The workflow starts with detecting and sorting defined populations of cells as well as individual cells using cellenONE, followed by multiplexing dPCR on the QIAcuity platform. Copy number variations of target regions are then analyzed using the QIAcuity Software Suite, providing an intuitive and fast interpretation of results.
