Sample GSM1517774 Query DataSets for GSM1517774
Status Public on Apr 02, 2015
Title H3A_shBRG1_rep1
Sample type SRA
 
Source name Hermes 3A
Organism Homo sapiens
Characteristics cell line: Hermes 3A
cell type: melanocyte
knockdown: shBRG1
Extracted molecule total RNA
Extraction protocol Total RNA isolation from 501M or Hermes3A cells was performed according to standard procedure (Qiagen kit). 1,5 μg of RNA was reverse transcribed using a mix 1/1 of SuperScript II RNase H-reverse transcriptase (Invitrogen) and AMV retrotranscriptase (Roche) with 500 ng of oligodT22 primer, hexanucleotides or specific primers according to the manufacter’s instructions
Total RNA-seq libraries were prepared following the Illumina protocol with some modifications. Briefly, 2 µg of total RNA was hybridized with rRNA sequence-specific 5’biotin labeled oligonucleotide probes to selectively deplete ribosomal RNA. The rRNA/5’biotin labeled probe was removed from the sample with streptavidin-coated magnetic beads. (Ribominus Eukaryote kit for RNA-seq, #A10837-08, Invitrogen Corporation). The rRNA depleted RNAs were then fragmented using divalent cations at 95°C for 5 minutes and used to generate a reverse transcribed cDNA library. 100 ng of each DNA library was then denatured at 98°C for 2 minutes, incubated at 68°C for 5 hours and then incubated in the presence Duplex-Specific thermostable Nuclease enzyme (DSN, #EA001, Evrogen) for DSN normalization following the Illumina protocol. DSN treated libraries were purified using Agencourt AMPure XP beads, enriched by PCR (30 sec at 98°C; [10 sec at 98°C, 30 sec at 65°C, 30 sec at 72°C] x 6 cycles; 5 min at 72°C) and purified again using Agencourt AMPure XP beads.
