| Channel 2 |
| Source name |
BC1_t30
|
| Organism |
Bacillus cereus ATCC 14579 |
| Characteristics |
treatment_protocol: OD600 0.5 exposed to Benzalkonium chloride 1 µg/ml for 30 min
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted as described by van Schaik et al., 2004
|
| 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.
