Sample GSM4490923 Query DataSets for GSM4490923
Status Public on Nov 24, 2020
Title Sso-RNAseq rep3
Sample type SRA
 
Source name S. solfataricus P2
Organism Saccharolobus solfataricus
Characteristics density: OD600 of 0.8
Treatment protocol Individual-nucleotide resolution crosslinking and immunoprecipitation (iCLIP) analyses were performed as described in König et al. (2010) (PMID: 20601959), with the following alteration that were necessary for the application in S. solfataricus. Cell pellets were washed with PBS, and 0.8 g were resuspended in 40 ml PBS at 4°C, and spread on a large petri dish swimming on an ice-water bath. The cell suspension was crosslinked four times at 254 nm, 300 mJ/cm², cells were mixed in between. Crosslinked cells were harvested as before and stored at -80°C.
Growth protocol S. solfataricus P2 was grown as previously described in a 10 l bioreactor (Evguenieva-Hackenberg et al., 2002) (PMID: 12359717). Cells were cultivated until an OD600 of 0.8 and harvested by centrifugation at 6,000 g and 4 °C for 10 min.
Extracted molecule total RNA
Extraction protocol The total RNA samples were first fragmented using ultrasound (4 pulses of 30 sec at 4°C). Each sample was used for three independent cDNA synthesis. First, an oligonucleotide adapter was ligated to the 3' end of the RNA molecules. First-strand cDNA synthesis was performed using M-MLV reverse transcriptase and the 3’ adapter as primer. The first-strand cDNA was purified and the 5' Illumina TruSeq sequencing adapter was ligated to the 3' end of the antisense cDNA. The resulting cDNA was PCR-amplified to about 10-20 ng/μl using a high fidelity DNA polymerase. The cDNA was purified using the Agencourt AMPure XP kit (Beckman Coulter Genomics) and was analyzed by capillary electrophoresis.
