Which NEBNext Product Format Should I Choose?
Ultra II Directional RNA Library Prep with Sample Purification Beads delivers significantly increased sensitivity and specificity from your RNA-seq experiments, from ever-decreasing amounts of input RNA. In conjunction with ribosomal RNA (rRNA) depletion or poly(A) enrichment, the kit enables the production of high quality libraries from 5 ng or 10 ng of Total RNA, respectively, up to 1µg.
This kit contains NEBNext Sample Purification Beads (SPRIselect® beads from Beckman Coulter) for size selection and enzyme reaction cleanup.
Strand-specific/directional methods for sequencing RNA provide information on the DNA strand from which the RNA strand was transcribed. This is useful for many reasons including: Identification of antisense transcripts, determination of the transcribed strand of noncoding RNA, and measurement of expression levels of coding or noncoding overlapping transcripts. Overall, the ability to determine the originating strand can substantially enhance the value of a RNA-seq experiment.
The NEBNext Ultra II Directional RNA Library Prep Kit derives its directionality from the “dUTP” method for strand-specificity, with proven superiority for this application.
