Title |
Rhododoccus jostii RHA1 cells were grown on membrane filter placed on W minimal solid medium with biphenyl, replicate 2 |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
solid-support dependent genes, Rhododoccus jostii RHA1 cells were grown on membrane filter placed on W minimal 2%-agar solid medium with vapor of biphenyl, replicate 2
|
Organism |
Rhodococcus jostii RHA1 |
Characteristics |
strain: Rhododoccus jostii RHA1 substrate: biphenyl medium: solid medium
|
Biomaterial provider |
none
|
Treatment protocol |
none
|
Growth protocol |
Rhodococcus jostii RHA1 cells were grown on membrane filter placed on W minimal 2%-agar solid medium with vapor of biphenyl at 30°C
|
Extracted molecule |
total RNA |
Extraction protocol |
Cell pellets were vortexed with glass beads, hot phenol, and SDS at final concentrations of 14.3% and 0.9% (vol/vol) respectively. Debris was precipitated with acetate followed by the addition of 4.0 mL phenol-chloroform (1:1, vol/vol). Nucleic acids were precipitated with acetate plus isopropanol, treated with DNase, and purified with an RNeasy mini column (Qiagen).

Label |
Cy3
|
Label protocol |
Cy-labelled cDNA was prepared by indirect labelling. the Cy3/Cy5 dyes were reversed to control for dye bias.

Hybridization protocol |
The microarray slides were pre-hybridized using 5X SSC containing 0.1% SDS and 0.2% BSA for 45 minutes at 48°C and used immediately for hybridization in a GeneTac HybStation (Genomic Solution). Equal amounts of differentially labelled cDNA – 50 million pixels as measured by ImageQuant 5.2 (Molecular Dynamics) – from T = 48 h and T = 0 cells were hybridized at 42°C for 17 h with agitation using 120 uL per slide of SlideHyb#1 hybridization solution (Ambion). The post-hybridization washing consisted of 3 cycles of 20 second incubations with each of the following solutions: 2X SSC plus 0.1% SDS (medium stringency) at 42°C; 0.1X SSC plus 0.05% SDS (high stringency) at 25°C; and 0.1X SSC (low stringency) at 25°C. Lastly, the slides were dipped in 0.2X SSC and dried by centrifugation at 225 x g for 5 min at room temperature.
|
Scan protocol |
Microarray slides were scanned with a GenePix 4000B scanner (Axon Instruments) and spot intensities were quantified using Imagene 6.1 (BioDiscovery, Inc.).
|
Description |
none
|
Data processing |
Expression ratios were normalized using GeneSpring version 7.3.1 (Silicon Genetics) by the intensity-dependent Lowess method, with 20% of the data used for smoothing. Replicate spots of the same type were combined to yield a single normalized ratio, which is output for the first ID_REF number representing that spot type.
