Sample GSM2538162 Query DataSets for GSM2538162
Status Public on Mar 15, 2017
Title MtbRaGyr
Sample type SRA
 
Source name Log/exponential phase Mtb H37Ra cells
Organism Mycobacterium tuberculosis H37Ra
Characteristics chip antibody: anti-gyrA (generated in-house, lot# VNMUH1996)
growth phase: Exponential
Treatment protocol M. tuberculosis cultures, either in exponential or stationary phase, were cross-linked with 1% formaldehyde for ten minutes at 37°C.
Growth protocol Mycobacterium tuberculosis H37Ra was grown at 37°C in 7H9 broth (Difco) supplemented with 0.2% glycerol, 0.05% Tween 80 and 10% albumin-dextrose-catalase (ADC, Middlebrook) or on 7H10 plates supplemented with 0.5% glycerol and 10% oleic acid-albumin-dextrose-catalase (OADC, Middlebrook). Logarithmic-phase cultures (exponential phase) were harvested at an optical density (OD600) of 0.4-0.6.
Extracted molecule genomic DNA
Extraction protocol Crosslinked bacteria cells were sonicated and protein-DNA complexes were isolated with No antibody (Mock) or anti-TopoI or anti-gyrA antibodies.
Libraries were prepared according to Illumina's instructions.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer IIx
