| Title |
Lactate_L_15 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Lactate_L t=0
|
| Organism |
Lactiplantibacillus plantarum |
| Characteristics |
time point: 0
strain: WCFS1
|
| Treatment protocol |
Harvested cultures were quenced in extraction mix containing Phenol/Chloroform, SDS, Na-acetate, glass-beads and TE buffer.
|
| Growth protocol |
Cultures were grown in batch fermentation on a chemically defined medium untill an optical density of 1.0 before being stressed with Na-L-lactate
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Cultures were lysed by beat-beating and total RNA was isolated by subsequent fenol extraction
|
| Label |
Cy5
|
| Label protocol |
10 µg of total RNA were primed with 2 µl of 100 µM T16N2 DNA primer at 70°C for 10 min, then reversed transcribed at 42°C for 3 h in the presence of 400 U SuperScript II RTase (Invitrogen), and 100 µM each dATP, dTTP, dGTP, with 25 µM dCTP, 25 µM Cy3-label

Lactate_L t=15 min
|
| Organism |

| |
| Hybridization protocol |
Hybridization buffer (Agilent In Situ Hybridization Kit Plus) was added, and samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers at 65 degrees Celcius for 17 h. After hybridization, slides were washed sequential
|
| Scan protocol |
Scanned on an Agilent G2565AA scanner. Images were quantified using Agilent Feature Extraction Software (version A.7.5)
|
| Description |
Lactate_L_15
|
| Data processing |
LOWESS normalized, background subtracted data obtained from log2 of processed Red signal/processed Green signal. Agilent software was used. Normalization across samples was performed by total signal correction
