Title |
yeastcells_control6hrsafterO.D.1.0_control2. |
Sample type |
RNA |
|
|
Source name |
Saccharomyces cerevisiae cells
|
Organism |
Saccharomyces cerevisiae |
Characteristics |
Saccharomyces cerevisiae, wt, maintianed on YPD plates, started from 48 hrs growth on a new YPD agar plate
|
Treatment protocol |
Cells were grown to O.D. of 1.0 and grown for 6 hours, then collected by centrifugation, frozen in liquid nitrogen, thawed before proecessing.
|
Growth protocol |
Cells were grown in YPD media at 30 degrees Celsius at 250 rpm shaker.
|
Extracted molecule |
total RNA |
Extraction protocol |
SDS/double phenol RNA extraction of total RNA was performed according to the manufacturer's instructions.
|
Label |
biotin
|
Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 6 microg total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
|
|
|
Hybridization protocol |
Following fragmentation, 10 microg of cRNA were hybridized for 16 hr at 45C on GeneChip YeastS98 Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
|
Scan protocol |
GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A.
|
Description |
We have examined the transcriptional response of S. cerevisiae to exposure to pyocyanin at 25 and 250 ?g/ml concentrations. Our analysis indicates that the changes are consistent with an oxidative stress response, as observed in other studies of the mode of action of pyocyanin toxicity.
|
Data processing |
The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 100.
