Sample GSM877351 Query DataSets for GSM877351
Status Public on Dec 30, 2018
Title sigW_B.plsY_1
Sample type RNA
 
Source name sigW_B.plsY
Organism Bacillus subtilis subsp. subtilis str. 168
Characteristics genotype: B. subtilis sigW mutant amyE::spaRK pNS8910::B.plsY
Growth protocol The strains listed were grown in Luria Bertani broth O.D. 600nm 1.0, at which point subtilin was added to a final concentration of 1%. The cells were grown for a further two hours at which point the cells were harvested for RNA isolation.
The complete description of the growth protocols can be found in Zweers et al., to be submitted
Extracted molecule total RNA
Extraction protocol Total RNA was isolated by the method described by Eymann et al. (PMID: 11948165) with minor modifications. The quality of the RNA preparations was assessed by means of the Agilent 2100 Bioanalyzer.
Label Cy3
Label protocol 10 µg of RNA were converted into Cy3-labeled cDNA by Roche NimbleGen (Madison, WI, USA) using the BaSysBio protocol for strand-specific hybridization (Rasmussen et al., 2009).
 
Hybridization protocol Hybridization was performed by Roche NimbleGen (Madison, WI, USA) following their standard operating protocol. See www.nimblegen.com.
Scan protocol Scanning was performed by Roche NimbleGen (Madison, WI USA) following their standard operating protocol. See www.nimblegen.com.
Description sigW mutant with B.plsY in overexpression plasmid_rep1
Data processing An aggregated expression value was computed for each Genbank annotated CDS and newly defined transcribed region as the median log2 expression signal intensity of probes lying entirely within the corresponding region.
The expression intensity was computed from the raw intensity data using a model of signal shift and drift and correcting for probe affinity variations as described in (Nicolas et al., 2009, Bioinformatics 25, 2341-2347)
To control for possible cross-hybridization artefacts the sequence of each probe was BLAST-aligned against the whole chromosome sequence and probes with a SeqS value above the 1.5 cut-off were discarded (Wei et al., 2008 Nucl. Acids Res. 36, 2926-2938).
