Sample GSM325756 Query DataSets for GSM325756
Status Public on Sep 28, 2009
Title Bexp_Kexp_rep1
Sample type RNA
 
Channel 1
Source name REL606, exponential phase, LB
Organism Escherichia coli
Characteristics REL606, exponential phase, LB
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from cells grown in LB medium using the Qiagen RNeasy column.
Label Cy3
Label protocol Fluorescently-labeled cDNA was synthesized by reverse transcription of total RNA with aminoallyl-dUTP and random primers followed by the coupling of Cy3 or Cy5 dyes (Amersham Pharmacia).
 
Channel 2
Source name MG1655, exponential phase, LB
Organism Escherichia coli
Characteristics MG1655, exponential phase, LB
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from cells grown in LB medium using the Qiagen RNeasy column.
Label Cy5
Label protocol Fluorescently-labeled cDNA was synthesized by reverse transcription of total RNA with aminoallyl-dUTP and random primers followed by the coupling of Cy3 or Cy5 dyes (Amersham Pharmacia).
 
 
Hybridization protocol Hybridization and washes were performed according to the instruction of the manufacturer (Digital Genomics).
Scan protocol The hybridized slides were scanned with GenePix 4000B (Molecular Devices) and scanned images were analyzed by GenePix Pro 6.0.
Description The microarray contains two large blocks, onto each of which the probes were spotted in duplicate. The data is for one of the blocks.
Data processing Following background subtraction, spot signal intensities were calculated as percentages of total signal intensities of Cy-3 or Cy-5 signals on each microarray, as a means of normalization. Spots with low intensities were excluded.
