An ideal library will represent completely and proportionally the sequence of the input RNA of interest. When library preparation is inefficient or when input amounts for a library are very low, there is a risk that the resulting library will lack this diversity, and that some sequences will be over- or under-represented. Correlation analysis shows that NEBNext Ultra II RNA libraries retain complexity even at low input amounts.

Libraries show superior complexity at a range of input amounts
