Low input NEBNext Ultra II Directional RNA libraries retain superior complexity
Dir_RNA_Complexity_Figure1
Poly(A)-containing mRNA was isolated from Universal Human Reference RNA (Agilent #740000), and libraries were made using the NEBNext Ultra II Directional RNA Kit (plus the NEBNext Poly(A) mRNA Magnetic Isolation Module), Illumina TruSeq Stranded mRNA Kit, Kapa Stranded mRNA-Seq Kit and Kapa mRNA HyperPrep Kit. Libraries were sequenced on an Illumina NextSeq® 500 using paired-end mode (2x76 bp). Salmon 0.6 was used for read mapping and quantification of all GENCODE v25 transcripts. TPM = Transcripts Per Kilobase Million. R2 values for the linear fit are shown. Correlation analysis of the transcripts indicates superior transcript expression correlation between the different inputs for Ultra II Directional RNA libraries.
