Sample GSM345014 Query DataSets for GSM345014
Status Public on Nov 25, 2009
Title Bc10987 pH5.0 t0_t60
Sample type RNA
 
Channel 1
Source name Bc10987 pH5.0 t0
Organism Bacillus cereus
Characteristics Bc ATCC 10987 OD600 0.5 exposed to pH5.0 for 0 min
Extracted molecule total RNA
Extraction protocol RNA was extracted as described by van Schaik et al., 2007
Label Cy3
Label protocol Complementary DNA was synthesized and labeled using 15 μg of total RNA, and the CyScribe Post-Labeling kit (Amersham Biosciences Europe GmbH) according to the supplier's instructions.
 
Channel 2
Source name Bc10987 pH5.0 t60
Organism Bacillus cereus
Characteristics Bc ATCC 10987 OD600 0.5 exposed to pH5.0 for 60 min
Extracted molecule total RNA
Extraction protocol RNA was extracted as described by van Schaik et al., 2007
Label Cy5
Label protocol Complementary DNA was synthesized and labeled using 15 μg of total RNA, and the CyScribe Post-Labeling kit (Amersham Biosciences Europe GmbH) according to the supplier's instructions.
 
 
Hybridization protocol The target was denatured by boiling for 1 min and immediate cooling on ice prior to hybridization. A total of 200ng of both samples was mixed and applied with the Agilent hybridization buffer to the microarray, according to Agilent manual. Hybridization was performed at 60 °C. The slide was washed according to the Agilent microarray wash protocol.
Scan protocol Microarrays were scanned with the Agilent DNA Microarray Scanner, Model G2565BA, according to the Agilent protocol at 50% laser intensity, and 10 micron scan resolution.
Description No extra description.
Data processing Lowess-normalization, performed in Feature Extract, Agilent. Subsequently normalized data was processed with the Vampire webbased microarray suite.
