Sample GSM3782960 Query DataSets for GSM3782960
Status Public on Jan 14, 2020
Title A3_A3SLMut1_293
Sample type SRA
 
Source name HEK293t cells transfected with HIV-1 NHG A3SLMut1
Organisms Homo sapiens; Human immunodeficiency virus 1
Characteristics human cell type or cell line: HEK293t cell line
infection or transfection: transfected with HIV-1 NHG A3SLMut1
Treatment protocol DMS-treatment for RNA secondary structure analysis, between 0.5-2% DMS at 37C for 5 minutes. Shake during DMS treatment for suspension cells.
Growth protocol HEK293t were grown in T75 and cultured in DMEM+ 10% FBS + Penn/strep. Transfections were done in 6-well plates with X-tremegene9.
Extracted molecule total RNA
Extraction protocol DMS-treated cells were pelleted and resuspended in 1 mL Trizol, RNA was extracted by phenol-chloroform extraction and isopropanol precipitation.
3' Phosphorylation with rSAP, linker ligation with T4 RNA ligase truncated KQ, excess linker degraded with RecJ and 5'Deadenylase. rRNA was subtracted with RiboZero, and RT was performed with TGIRT-III. cDNAs were isolated by gel extraction on a 10% TBE-Urea gel and extracted by isopropanol precipitation. cDNAs were circularized with circLigase and amplified by PCR with phusion polymerase. PCR products were purified by gel extraction from an 8% TBE gel and isopropanol precipitation. Samples were quantified by Bioanalyzer.
