Lyophilized NGS Enzymatic DNA Fragmentation Kit enables precise time-controlled, enzymatic DNA fragmentation for NGS library preparation, with ambient-temperature (15-25C) storage that removes coldchain constraints and supports more flexible, decentralized sequencing workflows. The fully lyophilized, glycerol-free format reduces workflow complexity, enabling more consistent performance across sites and scales and is compatible with established short-read library preparation workflows and is designed to support integration into NGS assay development and kit formats.
