Sample GSM5939442 Query DataSets for GSM5939442
Status Public on Jan 31, 2023
Title dC11a_2_min_stat_RNAPChIP [R144a_2_min_stat]
Sample type SRA
 
Source name Bacterial culture
Organism Escherichia coli
Characteristics strain: dC11 lrp at thyA
lineage: A
biological replicate: 2
media: Min
growth_phase: Stat
chip antibody: RNAP
Growth protocol Cells were grown in M9 Minimal media (Min) or the same media supplemented with 0.2% each of L-leucine, L-isoleucine, and L-valine (LIV) at 37 degrees Celcius until OD600 = 0.2 (log-phase) or 12 hours after log-phase (stat phase) and crosslinked with 1% formaldehyde
Extracted molecule genomic DNA
Extraction protocol Cell pellets were lysed and sonicated. Input samples were set aside and the remainder of each lysate was split in half where the Lrp-DNA complexes and RNAP-DNA complexes were isolated with their respective antibodies; Neoclone W0023 (the RNA polymerase antibody), lot # 2019G15-002, Lrp antibody is NeoClone custom antibody clone# 1G4D9A10, Lot# 2016E25-001.
ChIP-seq libraries were prepared for sequencing with the NEBNext UltraII DNA kit using an OpenTrons2 robot
 
Library strategy ChIP-Seq
