| Title |
cwc21-null expression profile |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Total RNA from a cwc21 null mutant
|
| Organism |
Saccharomyces cerevisiae |
| Characteristics |
strain: Y3656
|
| Growth protocol |
Cell cultures were grown to an early mid-log phase (OD600 0.8) in rich medium (YPD) at 30C while shaking.
|
| 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.

|
| |
| 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.
|
| Description |
cwc21-null expression profile
|
| 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.
