What is PacBio?

PacBio, short for Pacific Biosciences, is a biotechnology company that specializes in developing sequencing technologies capable of producing long reads. Their technology, known as Single Molecule, Real-Time (SMRT) sequencing, allows for the observation of DNA synthesis in real-time, providing detailed insights into genetic sequences. By producing longer reads, PacBio technology helps overcome the limitations associated with short-read sequencing methods.

How Does PacBio Sequencing Work?

PacBio sequencing operates using SMRT technology, which involves the use of zero-mode waveguides (ZMWs). These are small holes that allow light to illuminate a single DNA molecule as it is being synthesized. By observing the incorporation of fluorescently labeled nucleotides in real-time, PacBio can generate long-read sequences with high accuracy. This process provides a comprehensive view of the genome, making it ideal for analyzing complex genetic regions.
