P-GSE29879-1
normalization data transformation protocol
MAS 5.0 Expression Analysis Default Setting ID_REF = VALUE = Single intensity accepted from the probeset ABS_CALL = Probeset signal: absent or present DETECTION P-VALUE = Probeset signal: p-value (shows the coherency of the results)
P-GSE29879-5
array scanning protocol
Following affymetrix protocol. After washing and staining, the probe array was scanned using Affymetrix Genechip scanner GCS3000 7G system and the software GenomeChipOperating Software (GCOS).
P-GSE29879-4
hybridization protocol
Following affymetrix protocol. cDNA was synthesized first using Promega M-MLV Reverse transcriptase (cat# M1705). After removing RNA, DNA fragmentation was performed to obtain and 50-200 base cDNA fragments. The fragmented cDNA was labelled with Biotin-ddUTP using Enzo BioArray Terminal Labeling Kit (Affymetrix, P/N 900181).
P-GSE29879-3
labelling protocol
Following affymetrix protocol. cDNA was synthesized first using Promega M-MLV Reverse transcriptase (cat# M1705). After removing RNA, DNA fragmentation was performed to obtain and 50-200 base cDNA fragments. The fragmented cDNA was labelled with Biotin-ddUTP using Enzo BioArray Terminal Labeling Kit (Affymetrix, P/N 900181).
P-GSE29879-2
nucleic acid extraction protocol
The overnight culture (2.5 ml) was used to inoculate 250 ml of fresh LB medium with 10 g of submerged glass wool (Corning Glass Works, Corning, NY) for forming biofilm. After incubation for 15 h at 37°C with shaking (250 rpm), the glass wool was carefully and quickly removed and rinsed with 100 ml of sterile 0.85% NaCl solution at 0°C. Biofilm cells were removed by sonicating the glass wool in 200 ml of sterile 0.85% NaCl solution at 0°C. After breaking the cells with a bead beater, and the total RNA was isolated with Qiagen RNeasy mini Kit (Cat# 74104)
