| Title |
7_CK07_30S_2 |
| Sample type |
SRA |
| |
|
| Source name |
CK07_30S
|
| Organism |
Escherichia coli |
| Characteristics |
genotype/variation: {delta}7prrn-BBB
dms concentration: 100 mM
treatment time: 4 minutes
molecule subtype: Purified ribosomes; 30S ribosomal RNA
|
| Treatment protocol |
Ribosomes were treated for 4 min with 100mM DMS, and quenched with βME buffer.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Modified ribosomes were isopropanol precipitated, phenol extracted, reprecipitated.
rRNA was fragmented with Zinc Chloride for 5' @ 94C. 3' ends were resolved by treatment with T4 PNK, and RNA was size-selected by gel for ~60-70nt fragments.Preadenylated IDT miRNA cloning linker 2 was ligated with T4 PNK, and the ligated products gel purified. RT was performed with TGIRTIII RT @ 60C for 1 hour, and full-length RT products were gel purified. cDNA was circularized with circ ligase, and amplified by 11-13 cycles of PCR.
