Sample GSM1908669 Query DataSets for GSM1908669
Status Public on May 31, 2016
Title BHI+Bipy_t12 over BHI_t12 (2)
Sample type RNA
 
Channel 1
Source name BHI+Bipy_t12: cells grown with iron starvation in BHI+Bipy until t12
Organism Bacillus cereus ATCC 10987
Characteristics strain: ATCC 10987
Treatment protocol Cells were harvested at t5 and t12 hours of growth.
Growth protocol Liquid cultures of B. cereus ATCC 10987 were grown in BHI, BHI+Fe, BHI+Bipy and BHI+Fe+Bipy in 12-well plates statically at 30°C. 3ml was grown in each well and 8 such wells were pulled together for RNA isolation.
Extracted molecule total RNA
Extraction protocol Cultures were spinned down, resuspended in 1 ml TRI reagent (Ambion) and snap frozen in liquid nitrogen. RNA was extracted according to the RNAwiz (Ambion) protocol using Chloroform/isopropanol extraction. Residual DNA was enzymatically removed using the TURBO DNA-free (Ambion) kit following the instructions of the manufacturer.
Label cy3
Label protocol Cy3 and Cy5 labeling of the cDNA was performed with CyScribe Post-Labeling kit (GE Healthcare)
 
Channel 2
Source name BHI_t12: cells grown in BHI as control until t12
Organism Bacillus cereus ATCC 10987
Characteristics strain: ATCC 10987
Treatment protocol Cells were harvested at t5 and t12 hours of growth.
Growth protocol Liquid cultures of B. cereus ATCC 10987 were grown in BHI, BHI+Fe, BHI+Bipy and BHI+Fe+Bipy in 12-well plates statically at 30°C. 3ml was grown in each well and 8 such wells were pulled together for RNA isolation.

Residual DNA was enzymatically removed using the TURBO DNA-free (Ambion) kit following the instructions of the manufacturer.
Label cy5
Label protocol Cy3 and Cy5 labeling of the cDNA was performed with CyScribe Post-Labeling kit (GE Healthcare)
 
 
Hybridization protocol Hybridization was performed as described in Mols et al., 2013.
Scan protocol Slides were scanned with Agilent G2505C scanner
Description Expression patterns were studied with and without iron starvation
Data processing Data were normalized using Lowess normalisation as available in MicroPrep and corrected for inter-slide differences. Median intensity of the different probes per gene was selected as the gene expression intensity.
