Sample GSM7512288 Query DataSets for GSM7512288
Status Public on Jan 30, 2024
Title siDHX15_1 (biol rep 1)
Sample type SRA
Source name Flp-In T-Rex HEK293
Organism Homo sapiens
Characteristics cell line: Flp-In T-Rex HEK293
genotype: WT, siDHX15
Growth protocol Wild-type (WT) and GPATCH4 knockout (GP4KO) HEK293 Flp-In T-Rex cells or HEK293 Flp-In T-Rex cells transfected with non-target siRNAs (siNT) or those targeting DHX15 (siDHX15) were grown at 37°C in 5% CO2 in high glucose DMEM supplemented with 10% foetal calf serum .
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using TRI Reagent (Sigma-Aldrich) according to the manufacturer's instructions.
RiboMeth-seq: 5-10 ug of RNA was partially degraded by alkaline at denaturing temperatures. The size fraction 20-40 nt was purified on gels and linkers added using a system relying on a modified Arabidopsis tRNA ligase joining 2',3' cyclic phosphate and 5' phosphate ends. The library fragments were then sequenced on the Ion Proton platform. See Birkedal U, Christensen-Dalsgaard M, Krogh N, Sabarinathan R, Gorodkin J, Nielsen H.
