Sample GSM3059546 Query DataSets for GSM3059546
Status Public on Apr 26, 2019
Title A549 BoRed-Seq Ctrl Rep 2
Sample type SRA
Source name A549 human lung adenocarcinoma cell line
Organism Homo sapiens
Characteristics cell line: A549
sample type: Control (non-reduced) RNA
Treatment protocol Total RNA, including miRNAs, was extracted from mammalian cells. m7G residues were specifically reduced by treatment with NaBH4 in the presence of high concentrations of free m7GTP. Control samples were treated with acid-quenched NaBH4. The reduced m7G residues were subjected to nucleoside hydrolysis at low pH. A biotin-coupled aldehyde reactive probe (ARP) was covalently bound to the abasic RNA sites resulting from m7G reduction and hydrolysis, allowing pull-down with streptavidin-conjugated beads.
Growth protocol A549 cells were cultured in DMEM (Invitrogen), supplemented with 10% FBS and 1% penicillin/streptomycin/glutamine.
Extracted molecule total RNA
Extraction protocol Cells were lysed in Qiazol (Qiagen) and total RNA was purified using the miRNAeasy mini kit (Qiagen)
Libraries were prepared using the NEBNext SmallRNA kit (NEB) according to the manufacturer’s recommendations
