Fig. 2From: Current status of ctDNA in precision oncology for hepatocellular carcinomaSchematic workflow of droplet-based digital PCR (dPCR) and next-generation sequencing (NGS). dPCR consists of sample isolation, limited dilution, separations of a single sequence into each microcompartment, individual amplification, and immunofluorescence staining for specific sequence. NGS method profiles target genes by fracturing the DNA molecules into small sequences and proceeds with massive parallel sequencingBack to article page
