Sample GSM5623137 Query DataSets for GSM5623137
Status Public on Oct 15, 2021
Title RNAseq - LS180 cells, GFP_dox_neg_rep2
Sample type SRA
 
Source name LS180
Organism Homo sapiens
Characteristics cell type: Colorectal Cancer cells
cell line: LS180
doxycycline induction: -
expression: No doxycycline induced overexpression of GFP control
Treatment protocol GFP, SOX9 and mutant SOX9 was induced by doxycycline (0.5 µg/ml) for 24h. Each experiment was performed in duplicates.
Growth protocol LS180 cell line was obtained from Millipore Sigma and cultured in DMEM + 2mM Glutamine + 15% Fetal Bovine Serum (FBS) + 1% (P/S).
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using RNeasy Mini kit (Qiagen) according to the manufacture`s instruction.
Matured mRNA fraction was captured and enriched via oligo(dT) beads, then mRNAs were fragmented randomly in fragmentation buffer and the first-strand cDNA is synthesized using random hexamer primers and M-MuLV Reverse Transcriptase (RNase H-). The second strand was subsequently generated by dNTPs, DNA polymerase I and RNase H. Double-stranded cDNA molecules were purified by AMPure XP beads and overhanging ends are repaired to blunt ends by exonuclease/polymerase. After 5’ phosphorylation and 3’ adenylation, the cDNAs were ligated with P5/P7 sequencing adapters, then size selection (insert fragment of preferentially 150~200 bp in length) and library purification was performed using AMPure XP system (Beckman Coulter, Beverly, USA). The final library was created by amplification and subsequent AMPure XP beads purification.
RNA-Seq was performed using 150-bp paired-end sequencing chemistry (Illumina) at Novogene core facility.
