Sample GSM2138455 Query DataSets for GSM2138455
Status Public on Jun 21, 2017
Title Roemerine_60min_rep2
Sample type RNA
 
Source name (-)-Roemerine treatment, 60 min, replicate 2
Organism Escherichia coli
Characteristics strain: TB1
Treatment protocol When OD600 of the culture reached 0.54±0.06, cells were treated with 100 µg/ml of (-)-Roemerine. Since the alkaloid was dissolved in DMSO, control cells were also treated with the same amount of DMSO.
Growth protocol The pre-culture was the overnight propagated cells in 5 ml of LB medium at 37ºC and 180 rpm. The main bacterial culture was prepared by 1% inoculation from pre-culture when optical densities at 600 nm (i.e., OD600) reached 0.7. Growth was achieved in 50 ml of LB medium.
Extracted molecule total RNA
Extraction protocol Total RNA extraction was carried out based on the protocols given in the manual of QIAGEN - RNAprotect Bacteria Reagent Handbook, QIAGEN - RNeasy Mini Kit and QIAGEN - RNase-free DNase set. The concentration of each RNA sample was measured by Qubit® RNA BR Assay Kit (Invitrogen).
Label Cy3
Label protocol Cyanine-3 (Cy3) labeled cRNA was prepared from 100 ng RNA using the One-Color Low RNA Input Linear Amplification PLUS kit (Agilent) according to the manufacturer's instructions, followed by RNAeasy column purification (QIAGEN, Valencia, CA). cRNA was quantitated using NanoDrop ND-1000 UV-VIS Spectrophotometer version 3.2.1.
 
Hybridization protocol 10X Blocking Agent supplied with the Agilent Gene Expression Hybridization Kit and 2x GEx Hybridization buffer HI-RPM were used in preparation of hybridization assembly by following manufacturers instructions.Hybridization was carried out at 65oC for 17 hours. After hybridization, microarrays were washed 1 minute at room temperature with GE Wash Buffer 1 (Agilent) and 1 minute with 37°C GE Wash buffer 2 (Agilent), then dried immediately by brief centrifugation.
Scan protocol Slides were scanned immediately after washing on the Agilent C Scanner using one color scan setting for 1x44k array slides (Scan Area 61x21.6 mm, Scan resolution 3 µg, Dye channel is set to Green and Green PMT is set to 100%).
Description Gene expression after 60 min. in Roemerine treated E.coli cells
Data processing Raw Microarray data evaluation including preprocessing, normalization, grouping the differentially expressed genes and statistical analyses with Moderated T-test and Bonferroni FWER was carried out with GeneSpring 13.0 Software.
