The NEBNext UltraExpressDNA Library Prep Kit is compatible with high-quality human genomic DNA, cell-free DNA (cfDNA) and DNA from other species (e.g., microbial, plant, etc.).
We do not recommend this kit for use with FFPE DNA. For FFPE DNA, consider the NEBNext UltraShear FFPE DNA Library Prep Kit (NEB #E6655).
