Pac Bio
•No amplification required
•Single molecule
•Several thousand base reads
(4 to 20 kb)
• Least GC-biased sequencing
•Run time 30 minutes
Applications
•Genomes: Finish Genomes and improve assembly with
extra long reads (4000bp average and up to 20,000)
• Genomic Complexity: Allow haplotype expansion, full
length transcripts and splice variants, repeat expansions,
minor variants
•Epigenome: Detects base modifications using kinetics
