, Introduction
Determination of precise order of nucleotides
within a DNA molecule.
Make things bigger, better, faster, cheaper:
• less input DNA, simpler library preparation, less
reagents (no “washing”)
• smaller, less expensive machines
• reduced run time
• longer reads
• better quality
• higher throughput
