NEBNext Ultrashear® FFPE DNA Library Prep Kit

FFPE DNA poses many challenges for library preparation, including low input amounts and highly variable damage from fixation, storage, and extraction methods. Regions of interest are often enriched using hybrid capture-based approaches, and these workflows require a high input of diverse, uniform DNA library.

The NEBNext Ultrashear™ FFPE DNA Library Prep Kit incorporates enzymatic fragmentation of FFPE DNA using NEBNext UltraShear, a new enzyme mix optimized for use with FFPE DNA that increases library yields and quality, while improving scalability and ease of use. The kit also repairs damage to DNA caused by the FFPE process and includes reagents and a protocol optimized for library prep of FFPE DNA. The workflow is streamlined and user-friendly, with minimal hands-on time, and the kit improves yields and quality of libraries from a range of FFPE DNA sample input (5-250 ng) and quality.
