Sample GSM5436903 Query DataSets for GSM5436903
Status Public on Jun 08, 2022
Title Non_targeting_1
Sample type SRA
 
Source name DNA
Organism Escherichia coli str. K-12 substr. MG1655
Characteristics tissue: bacterial culture
sample: Sample without nuclease
biological replicate: 1
Extracted molecule genomic DNA
Extraction protocol Library was transformed in cells with or without Cas13a and backdiluted 1:100 in LB with antibiotics to reach OD 0.06 and let grow for 12 hours shaking at 37°C. Finally, the library was midi-prepped with ZymoPure II Plasmid Midiprep Kit (Zymo Research, D4200).
The library prep was amplified with Kapa Hifi polymerase (Kapa Biosystems- Roche, 7958889001) according to the provider protocol. The reactions were purified using Ampure beads and further amplified to add the appropriate indexes and illumina adaptors. The resulting product was again purified with Ampure beads and run on a gel to verify the presence of the correct amplicon. The samples were sent for Sanger sequencing to make sure to get the expected sequence and then their quality was checked at the Bioanalyzer. Finally, they were sent for sequencing at the Next Seq sequencer (Illumina) with a 150 bp paired-ends kit (130 million reads) to get 1000x coverage. To increase the library diversity, 20% of phiX phage was spiked-in.
