Microwell displacement amplification system (MIDAS), a parallel polymerase cloning system for single-cell genome sequencing

MIDAS enables massively parallel polymerase cloning, which decreases bias and improves efficiency in single-cell genome sequencing. Single cells are seeded in microarray wells in 12 nL reaction volumes, subjected to single-round amplification and extraction for library generation and DNA sequencing analyses. In proof-of-concept analyses of Escherichia coli, MIDAS decreased amplification bias and increased efficiency compared with conventional methods. Next steps include using the system to explore the possibility that genetic mosaicism in adult neurons influences cognitive function or neurodegenerative disease.
