Sample GSM2492341 Query DataSets for GSM2492341
Status Public on May 02, 2017
Title S3 HeLa cells CF25Im KD
Sample type SRA
 
Source name HeLa Cells in culture
Organism Homo sapiens
Characteristics cell line: HeLa
treatment: CF25Im KD
Extracted molecule total RNA
Extraction protocol TRIzol Extraction from cells in culture
Poly(A)-ClickSeq (PAC-seq) libraries where generated using oligo-dT primers carrying partial p7 Illumina adaptors in RT-PCR reactions supplemented with azido-terminating nucleotides (AzVTPs). Azido-blocked cDNAs covering the junction of the 3'UTR and poly(A) tails were thus generated and were 'click-ligated' to p5 Illumina sequencing adaptors using the 'ClickSeq' methodology. These cDNA libraries were amplified by PCR to fill-in the Indexing sequences and the rest of the p7 adaptor.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 1500
 
Data processing CASAVA or MiSeq Reporter demultiplexing
Custom trimming and filitering to remove poly(A) tails (See Routh et al)
Mapping of processed reads to hg19 with HiSat2
Custom Scripts to extract poly(A) site and frequency (see Routh et al)
Genome_build: hg19
Supplementary_files_format_and_content: BEDGraph (4 tab-delimted columns: chromosome number \t start coordinate \t end coordinate \t read count)
