Pacific Biosciences has launched new sequencing kits that increase average read lengths to more than 4,300 bases and increase throughput to between 200 and 250 megabases per SMRT cell.

The higher average read length and throughput are a result of new chemistry, including a modified enzyme, and an increased movie time from 90 minutes to 120 minutes.

The new chemistry, dubbed XL, is available to customers now, and the company is currently in the process of rolling out upgrades for its installed base.
