ERCC transcript correlation
Dir_RNA_Complexity_Figure2
Poly(A)-containing mRNA was isolated from Human Universal Reference RNA (Agilent #740000) with recommended amounts of ERCC RNA Spike-In Mix I (Thermo Fisher Scientific #4456740), 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 0.4.0 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 ERCC spike-ins. The curved fit is a consequence of log transformation.
