| Title |
20 Min Treated Cy3 vs. Control Cy5 Rep. 3 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Streptococcus mutans, untreated, 20 min
|
| Organism |
Streptococcus mutans UA159 |
| Characteristics |
treatment: untreated
cell type: biofilm
genotype: wildtype
time point: 20 min
|
| Treatment protocol |
biofilm cells were treated with 0.25 µg/ml carolacton, control wells without treatment
|
| Growth protocol |
biofilms were grown in THBS medium for 3.5 hours (initial OD600 = 0.05) in 24 well polystyrene plates (Greiner, Germany), than the medium was exchanged against fresh THBS supplemented with and without carolacton (0.25 µg/ml)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
total RNA was extracted using the RNeasy Mini Kit (Qiagen, Germany)
|
| Label |
Cy5
|
| Label protocol |
RNA samples were labelled either with Cy3 or Cy5 using the ULS fluorescent labelling kit (Kreatech, Germany)

|
| Organism |
Streptococcus mutans UA159 |

|
| Label |
Cy3
|
| Label protocol |
RNA samples were labelled either with Cy3 or Cy5 using the ULS fluorescent labelling kit (Kreatech, Germany)
|
| |
|
| |
| Hybridization protocol |
760 ng of each Cy3- and Cy5 labelled RNA was fracmented and hybridised to the microarray at 65°C for 16 h using the Agilent Hybridisation Chamber and Agilent Hybridisation Kit according to the manufacturer`s instructions.
|
| Scan protocol |
the array was scanned using the Agilent DNA Microarray Scanner at 5 µm resolution and the raw data were extracted using Agilent Feature Extraction software (V9.5)
|
| Description |
20 Min DyeSwap 2/2, Repl. 3
|
| Data processing |
The data were processed by Bioconductor packages written in R language (http://www.r-project.org). The linear models for microarray analysis (LIMMA) package was used for background correction, Loess normalisation of the two chanels of one array, quantile-normalisation between different arrays and identification of differentially expressed genes.
