Sample GSM7703758 Query DataSets for GSM7703758
Status Public on Aug 08, 2024
Title NitrogenMinus, RNA-seq, Replicate 1
Sample type SRA
 
Source name archaeal cell
Organism Methanosarcina mazei Go1
Characteristics cell type: archaeal cell
growth condition: NitrogenMinus
fraction: rRNA-depleted, fragmented total RNA
Treatment protocol No treatment applied during growth.
Growth protocol M. mazei Gö1 was cultivated either under nitrogen sufficient (+N) or nitrogen limited conditions (-N) as described (Ehlers et al. 2002). Cells corresponding to 60 OD600 equivalent units were harvested rapidly by fast-chilling in an ice bath to halt cell growth and translation, without the use of antibiotics
Extracted molecule total RNA
Extraction protocol RNA was extracted from fractions or cell pellets for total RNA using hot phenol-chloroform-isoamyl alcohol (25:24:1, Roth) or hot phenol (Roth), respectively, as described previously (Sharma et al. 2007).
Total RNA was first rRNA-depleted, fragmented then subjected to cDNA library preparation. Size selcted RNA for Riboseq samples were directly subjected to cDNA library preparation. The obtained small RNA samples were first treated with Antarctic Phosphatase and re-phosphorylated with T4 Polynucleotide Kinase (PNK). Then, oligonucleotide adapters were ligated to the 5' and 3' ends of the RNA samples. First-strand cDNA synthesis was performed using M-MLV reverse transcriptase and the 3’ adapter as primer. The resulting cDNA was amplified with PCR using a high fidelity DNA polymerase.
