Twist's rationally sculpted libraries are unparalleled in quality and composition

Building a high-quality next generation sequencing (NGS) library starts long before sequencing. The Twist Mechanical Fragmentation Library Prep Kit workflow is engineered to give you precise control at every step, from how your DNA is fragmented, through adapter ligation and indexing, to a clean, amplified, sequencing-ready library. Whether you're starting with mechanically sheared genomic DNA (gDNA) or letting enzymatic chemistry handle fragmentation, both paths converge on the same outcome: consistent, reproducible libraries with exceptional on-target performance.
