Sample GSM2233489 Query DataSets for GSM2233489
Status Public on Feb 16, 2018
Title TAW5, Replicate 14
Sample type RNA
 
Channel 1
Source name TAW5
Organism Bacillus subtilis
Characteristics replication genotype: oriC- oriN+
dnaa, sda, and spo0a genotype: Pspank-dnaA
Growth protocol Cells were grown to mid-log phase in batch culture at 37 °C in minimal media supplemented with 1% (w/v) arabinose, 0.5% (w/v) xylose, 0.1 mM IPTG, 40 µg/ml tryptophan, and 40 µg/ml phenylalanine.
Extracted molecule total RNA
Extraction protocol Cultures were fixed with an equal volume of -20C methanol. RNA was extracted using the Qiagen RNeasy kit according to the manufacturer's instructions.
Label Cy5
Label protocol 10 µg of each RNA sample was reverse transcribed using Superscript II reverse transcriptase (Invitrogen), random hexamers, and aminoallyl-dUTP (Ambion). The cDNA was labeled by conjugation to monofunctional Cy3 or Cy5 dyes (Amersham) for reference or experimental samples, respectively. Each experimental sample was mixed with an aliquot of reference sample.
 
Channel 2
Source name Reference RNA
Organism Bacillus subtilis
Characteristics reference rna: Includes pooled total RNA from B. subtilis cultures grown in defined minimal medium and cultures treated with DNA-damaging agents, as described in PMID 19737352
Growth protocol Cells were grown to mid-log phase in batch culture at 37 °C in minimal media supplemented with 1% (w/v) arabinose, 0.5% (w/v) xylose, 0.1 mM IPTG, 40 µg/ml tryptophan, and 40 µg/ml phenylalanine.

Label Cy3
Label protocol 10 µg of each RNA sample was reverse transcribed using Superscript II reverse transcriptase (Invitrogen), random hexamers, and aminoallyl-dUTP (Ambion). The cDNA was labeled by conjugation to monofunctional Cy3 or Cy5 dyes (Amersham) for reference or experimental samples, respectively. Each experimental sample was mixed with an aliquot of reference sample.
 
 
Hybridization protocol Salmon testes DNA and yeast tRNA were added, and each cDNA sample was hybridized to a DNA microarray at 42 °C overnight.
Scan protocol Scanned on a GenePix 4000B scanner. Images were quantified using GenePix 3.0 (Axon Instruments).
Data processing Loess normalized and background subtracted using the R statistical software package Linear Models for Microarray Data (LIMMA). [RGbkgd <- backgroundCorrect(RG, method=normexp, offset=50); normalizeWithinArrays(RGbkgd)]
