Sample GSM8756958 Query DataSets for GSM8756958
Status Public on Feb 10, 2025
Title 1h/LB_G1_xxx-rep2, SVb3-12
Sample type SRA
 
Source name bacterial
Organism Vibrio cholerae C6706
Characteristics cell type: bacterial
genotype: Wild type
treatment: LB + 0.125 µM anti-OSP G1
Treatment protocol Bacterial cultures were diluted to sub-agglutinating conditions of an optical density at 600 nm (O.D.600) of ≤ 0.1 in either LB or LB containing 1% w/v mucin (LBM) and exposed to human monoclonal immunoglobulin (Ig) G1 targeting V. cholerae O-specific polysaccharide component of LPS (clone G1 - CF21.2.G01) and flagellin (clone B12 -AT11.1.B12) for one hour at room temperature
Growth protocol Prio to exposure to antibody, V. cholerae El Tor O1 strain C6706 were grown in toxin-inducing-conditions in AKI media (1.5% Bacto-Peptone, 0.4% yeast extract, 0.5% NaCl) supplemented with sodium bicarbonate to a final concentration of 0.3% w/v without agitation at 37 ºC for four hours.
Extracted molecule total RNA
Extraction protocol Bacterial cultures were then pelleted, and total RNA was isolated using Lysozyme and RNeasy (Qiagen) per manufacturer’s instructions.
RNA was depleted of ribosomal RNA using a ribosomal depletion kit (NEB) and RNA-seq libraries were constructed using NEBNext Ultra II Directional kit per manufacturer’s instructions.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model NextSeq 2000
 
Description Library name: SVb3-Sample 6
Data processing Sequencing reads were mapped to V. cholerae O1 biovar El Tor strain N16961 chromosome I and II separately by using the program Rockhopper.
For differential expression analysis, we used EdgeR, and classified genes as differentially expressed based on the cutoffs of 1.5-fold change in expression value and false discovery rates (FDR) below 0.05.
Assembly: N16961_v2
