| Title |
BF638R_fur_mut High iron Rep1 |
| Sample type |
RNA |
| |
|
| Source name |
Bacteroides fragilis 638R fur deletion mutant
|
| Organism |
Bacteroides fragilis 638R |
| Characteristics |
genotype: fur deletion mutant
growth condition: high iron
|
| Treatment protocol |
Bacterial cultures were grown to mid-logarithmic phase (O.D. 550 nm of 0.3-0.4) and submitted to total RNA extract by the hot phenol method.
|
| Growth protocol |
Overnight cultures of Bacteroides fragilis 638R wild type or mutant strains were diluted into minimal defined media supplemented with 5 microgram/ml protoporphyrin IX containing 100 micromolar iron sulfate, 50 micromomolar 2,2-bipyridyl, 5 microgram/ml hemin, or 0.1 microgram/ml hemin.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated by the hot phenol method and treatd as described by Sund et al., 2008, Mol. Microbiol. 67:129-142.
|
| Label |
Cy3
|
| Label protocol |
Labeling was peformed by at the FSU Nimblegen Microarray Facility using standard protocols as described previously (Sund et al., 2008, Mol Microbiol. 67:129-142).
|
| |
|
| Hybridization protocol |
Hybridization was performed by at the FSU NimbleGen Microarray Facility, using standard protocols as described previously (Sund et al., 2008, Mol. Microbiol. 67:129-142)
|
| Scan protocol |
Scanning was performed by at the FSU NimbleGen Microarray Facility, using standard protocols as described previously (Sund et al., 2008, Mol. Microbiol. 67:129-142)
|
| Description |
This sample is of the Bacteroides fragilis 638R fur deletion mutant first of two independent biological replicates from two separate cultures in high iron conditions.
|
| Data processing |
Raw data (pair files) were subjected to RMA (Robust Multi-Array Analysis; Irizarry et al. Biostatistics 4(2):249), quantile normalization (Bolstad et al. Bioinformatics 19(2):185) using NimbleGen Systems DEVA 1.1 software as described on their web site. The RMA processed data was averaged and log2 transformed (see *.calls files).
