This original version of the Ultra Directional RNA Library Prep Kit enables strand-specific RNA library preparation in a streamlined workflow. However, we now recommend the new NEBNext Ultra II Directional RNA Library Prep Kit for Illumina (NEB #E7760), which has been further optimized to provide increased yields of high quality libraries from a broader range of input amounts.
