How Does SMRT Sequencing Work?

SMRT sequencing, the cornerstone of Pac Bio's technology, operates on a simple yet powerful principle: observing DNA synthesis as it happens. The process begins with the preparation of SMRTbell libraries, where DNA fragments are circularized and loaded onto a sequencing chip known as a SMRT Cell. Each SMRT Cell contains thousands of tiny wells, each hosting a single DNA molecule. As DNA polymerase enzymes incorporate fluorescently labeled nucleotides, the system records the emitted light in real-time, generating a continuous read of the DNA sequence. This real-time capture allows for the detection of methylation and other epigenetic modifications, providing a comprehensive view of the genome.
