| Title |
Dbat vs. bat+ |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
wild type
|
| Organism |
Halobacterium salinarum NRC-1 |
| Characteristics |
strain: NRC-1
genotype: wild type
|
| Treatment protocol |
Cells were chilled prior to nucleic acid extraction.
|
| Growth protocol |
Cells were grown to early log phase for all samples except the bat cultures, which were grown to log phase, in CM+ or modified CM+ media (see DasSarma, S., and E. M. Fleischmann. 1995. Halophiles. Cold Spring Harbor Laboratory Press, Plainview, N.Y.)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was isolated immediately after cell harvest using spin columns (Agilent, Palo Alto, Calif.).
|
| Label |
Cy3
|
| Label protocol |
Total RNA was combined with 500 ng of random hexamers (Qiagen) and reverse transcribed to Cy3- or Cy5-dCTP (Amersham Pharmacia)-labeled cDNA using SuperScript II RNase H_ reverse transcriptase (Invitrogen).
|
| |
|
| Channel 2 |
| Source name |
knockout of bat gene
|
| Organism |
Halobacterium salinarum NRC-1 |
| Characteristics |
strain: NRC-1
genotype: bat knockout
|
| Treatment protocol |

|
| Label |
Cy5
|
| Label protocol |

|
| |
|
| |
| Hybridization protocol |
Labeled cDNA targets were mixed with hybridization buffer (Agilent) and hybridized to microarray slides, which were assembled into a hybridization chamber (Agilent) for 17 h at 65°C in the dark.
|
| Scan protocol |
Slides were scanned for the Cy3 and Cy5 fluorescent signals using an Agilent DNA microarray scanner.
|
| Description |
This Sample represents 2 replicate samples.
bat1.txt: Cy3=wild type, Cy5=bat knockout
bat2.txt: Cy3=wild type, Cy5=bat knockout
|
| Data processing |
Image processing was carried out using Agilent Feature Extraction software. Data from replicate arrays were analyzed using the Agilent microarray data analyzing software GeneSpring version 11.5.1. Green and red signal intensities of the probes were imported using a custom-created single-color technology.
