How does Pac Bio technology work?
At the core of Pac Bio's sequencing technology is the Single Molecule Real-Time (SMRT) sequencing method. Unlike traditional sequencing approaches that require DNA amplification, SMRT sequencing reads DNA in its natural state, providing more accurate and comprehensive results.
The process begins with the preparation of SMRTbell libraries, where DNA is circularized. These libraries are then loaded onto a SMRT cell, where sequencing takes place. The SMRT cell contains millions of zero-mode waveguides (ZMWs), which are tiny observation chambers where DNA polymerase incorporates fluorescently labeled nucleotides into a growing DNA strand. Each incorporation event emits a light pulse, which is captured in real-time, allowing for the sequencing of long, continuous reads.
