Library preparation for Illumina sequencing. S2 cells expressing the inducible Hsp70 reporter were treated with dsRNA as indicated in the text. Reporter gene transcription was induced with CuSO4 for 1 h, and total RNA was isolated. After barcoded linker addition, PCR was performed as indicated. A size selection (bracket) was performed for products of 200–300 nt, which were subsequently analyzed by Illumina sequencing.
