Advantages | • Long reads • High quality | • Long reads • Fast run time | • Highest throughput • Low per-base cost | • Unmodified nucleotides • No optical scanning necessary, and thus no photo damage • Fast run time | |||
Limitations | • Low throughput • High costs | • High error rates in homopolymer regions • Low throughput • High costs • Cumbersome emPCR | • Short reads • Random dispersion of clusters can cause poor sequence quality • Underrepresentation of AT-rich and GC-rich regions | • High error rates in homopolymer regions • Cumbersome emPCR | |||
