The ultra II DNA library prep kit for Illumina meets the challenge of constructing high quality libraries from ever-decreasing input quantities.

• Get more of what you need, with the highest library yields
• Use to generate high quality libraries from a broad range of input amounts, from 500 pg to 1 µg
• Prepare libraries from all your samples, including GC-rich DNA and FFPE DNA samples
• Improve yields and quality for target enrichment applications
• Save time with streamlined workflows, reduced hands-on time and automation compatibility

The reagents for each step in the library preparation workflow have been reformulated to enable high yield preparation of high quality libraries from 500 picograms to 1 microgram of input DNA. This new generation of NEBNext reagents uses a fast, streamlined, automatable workflow and enables use of fewer PCR cycles while also improving GC coverage. The kit is also compatible with PCR-free workflows and is effective with challenging samples such as FFPE DNA.
