We have streamlined the SMRTbell library generation protocols with improved workflows to deliver seamless end-to-end solutions from sample to analysis. A key improvement is the development of a single-tube reaction strategy that shortened hands-on time needed to generate each SMRTbell library, reduced time-consuming AM Pure purification steps, and minimized sample-handling induced gDNA damage to improve the integrity of long-insert SMRTbell templates for sequencing. The improved protocols support all large-insert genomic libraries, multiplexed microbial genomes, and amplicon sequencing. These advances enable completion of library preparation in less than a day (approximately 4 hours) and opens opportunities for automated library preparation for large-scale projects. Here we share data summarizing performance of the new SMRTbell Express Template Kit 2.0 representing our solutions for 10 kb and >50 kb large-insert genomic libraries, complete microbial genome assemblies, and high-throughput amplicon sequencing. The improved throughput of the Sequel System with read lengths up to 30 kb and high consensus accuracy (> 99.999% accuracy) makes sequencing with high-quality results increasingly assessible to the community.
