| Title |
KT_KT_with_cation_2 |
| Sample type |
RNA |
| |
|
| Source name |
cDNA prepared from KT2440 incubated in CF buffer with cation
|
| Organism |
Pseudomonas putida KT2440 |
| Characteristics |
strain: KT2440
|
| Treatment protocol |
The cells were suspended in 4 mL CF buffer and the turbidity of donor and the recipient was adjusted to 2.0 at 600 nm. As for the mixture samples of donor and recipient, each 4 mL suspension was mixed in the 50 mL tube. For the donor and recipient samples, the 4 mL of each culture was mixed with another 4 mL CF buffer in 50 mL tube. The concentration of the cations was set to 0 μM or 400 μM (CaCl2 and MgSO4), respectively. The mating duration was 24 h.
|
| Growth protocol |
Donor (Pseudomonas fluorescens Pf0-1) and recipient (Pseudomonas putida KT2440) were grown overnight in 1/2LB. The cells were harvested by centrifugation and washed five times by CF buffer.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
The cells were treated with RNA Protect Bacteria reagent (Qiagen, CA, USA). Total RNA was extracted using NucleoSpin RNA II (Macherey-Nagel, Düren, Germany) and RNeasy Midi kit (Qiagen). The eluted RNA was treated with RQ1 RNase-free DNase (Promega, Madison, WI). After inactivation of DNase by the addition of the provided stop reagent and subsequent incubation, total RNA was repurified using NucleoSpin RNA Clean-up (Macherey-Nagel). cDNA was synthesized using SuperScript II (Invitrogen, Carlsbad, CA) in the presence of actinomycin D (Sigma, St.Louis, MO) to prevent generation of spurious second-strand cDNA.
|
| Label |
biotin
|
| Label protocol |
Labelling of the cDNA was achieved using a GeneChip WT Double-Stranded DNA Terminal Labeling Kit (Affymetrix, Santa Clara, CA).
|
| |
|
| Hybridization protocol |
The labelled samples were hybridized individually with each chip using a GeneChip Hybridization Oven 640 (Affymetrix) at 60 rpm and 50°C for 16 h. The chips were then washed and stained using a Hybridization, Wash and Stain Kit (Affymetrix) according to a modified version of the FleX450-0005 protocol of the GeneChip Fluidics station 450 (Affymetrix)
|
| Scan protocol |
Signals were detected using a GeneChip Scanner 3000 7G (Affymetrix).
|
| Description |
This is an Affymetrix custom-commercial tiling array that covers the Pseudomonas putida KT2440 chromosome (RefSeq: NC_002947) at 11-bp density. BPMAP files are provided as supplementary files. KT2440b520511FR-3.bpmap represents the forward strand of KT2440 chromosome, and KT2440b520511FF-3.bpmap represents the reverse strand of KT2440 chromosome.
|
| Data processing |
The CEL files were generated using Affymetrix GCOS. Data was quantile normalized and analyzed with Affymetrix Tiling Analysis Software v1.1, which uses non-parametric quantile normalization and a Hodges-Lehmann estimator for fold enrichment.The intensities were linearly scaled so that the median was 100. Each CEL file was converted into the BAR files using KT2440b520511FR-3.bpmap for the forward strand and KT2440b520511FF-3.bpmap for the reverse strand; the BAR files with F indicate the forward strand and with R indicate the reverse strand of KT2440 chromosome. Bandwidth: 30, Threshold: 0, MaxGap: 30, MinRun, 30.
