Sample GSM1093290 Query DataSets for GSM1093290
Status Public on May 22, 2013
Title REB1_ts [transcript profile]
Sample type RNA
 
Channel 1
Source name REB1 temperature-sensive strain grown at restrictive temperature
Organism Saccharomyces cerevisiae
Characteristics strain background: BY4741, MATa his3Δ1 leu2Δ0 met15Δ0 ura3Δ0 KanMX::reb1-212-URA3
genotype/variation: REB1 temperature-sensive strain
Growth protocol Temperature-sensitive strains were grown at 22°C (permissive temperature) until mid-log phase. An equal volume of hot medium was then added to equilibrate the culture to 37°C (restrictive temperature), followed by a further 3 to 7 hours incubation at this temperature until a difference in OD between the mutant strain and its corresponding wild-type control became apparent.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from yeast cells by vortexing with glass beads in the presence of hot acid phenol and cleaned by phenol:chlorophorm extraction followed by ethanol precipitation. After DNaseI (GE Healthcare) treatment to remove residual genomic DNA, 25 ug of total RNA was incubated with random hexamers at 70C for 10 min, incubated at 15C for 30 min and reverse transcribed to single-stranded cDNA for 2 hours at 42C with Superscript II (Invitrogen) in the presence of 6 μg/ml Actinomycin D to prevent antisense artifacts. RNA was subsequently removed by hydrolysis and cDNA was cleaned up and concentrated on MinElute PCR purification columns (Qiagen).
Label Biotin
Label protocol cDNA was fragmented by nuclease digestion in a solution containing 1X One-Phor-All buffer (GE Healthcare) and DNase I (GE Healthcare) at 37ーC until the average fragment size was approximately 70 bp. The fragmentation reaction was stopped by incubating at 95C for 10 min. Fragmented samples were biotinylated with Biotin-N6-ddATP (Enzo Life Sciences) using terminal deoxynucleotidyl transferase at 37C for 2 hours.
 
Channel 2
Source name total RNA from matched wild type control
Organism Saccharomyces cerevisiae
Characteristics strain background: BY4741, MATa his3Δ1 leu2Δ0 met15Δ0 ura3Δ0
genotype/variation: wild type
Growth protocol Temperature-sensitive strains were grown at 22°C (permissive temperature) until mid-log phase. An equal volume of hot medium was then added to equilibrate the culture to 37°C (restrictive temperature), followed by a further 3 to 7 hours incubation at this temperature until a difference in OD between the mutant strain and its corresponding wild-type control became apparent.

Hybridization protocol 6 μg of biotinylated cDNA was hybridized at 45C for 16 hours, and then washed and stained according to Affymetrix protocol EukGE-WS2v4_450 in an Affymetrix Fluidics Station 450.
Scan protocol Arrays were scanned in an Affymetrix 7G scanner.

REB1_ts
Expression profile for REB1 temperature-sensive strain grown at restrictive temperature compared to wild-type control
Data processing Raw data files were normalized with Affymetrix Tiling Analysis Software (TAS) v1.1. Treatment and control samples were quantile normalized in pairs using only perfect match probes with a bandwidth of 20. The files ending in 'forward.bar' and 'reverse.bar' correspond to normalized signals from the forward and reverse strand, respectively.
