U1 RAP-RNA-Seq analysis of A2Lox mouse embryonic stem cells treated with a control or Srrt-specific siRNA. U1 RAP-RNA-Seq analysis of A2Lox mouse embryonic stem cells treated with a control or Srrt-specific siRNA

The experiment was carried out to examine the effect of Srrt knockdown on the U1 snRNP/pre-mRNA interaction pattern. A2Lox mouse embryonic stem cells were transfected with either an Srrt-specific or a non-targeting siRNA. 48 hours post transfection the cells were cross-linked using 2% formaldehyde and lysed. RNA was partially fragmented by sonication, hybridized with U1 snRNA-specific biotinilated probes and pulled down. U1-associated RNA sequences were then purified and RNA-seq libraries were generated using a NEBNext® rRNA Depletion Kit and NEBNext® Ultra8482 II Directional RNA Library Preparation kit. Paired-end sequencing was performed using a HiSeq4000 75bp platform.
