Sample GSM367221 Query DataSets for GSM367221
Status Public on Apr 01, 2009
Title S.cerevisiae and S.paradoxus at rich media (SC) repeat #2 Cy5
Sample type RNA
Source name S. cerevisiae (BY4741 ho::kanMX4 MATa), S. paradoxus (CBS432 ho::nat1 MATα)
Organisms Saccharomyces cerevisiae; Saccharomyces paradoxus
Characteristics strain: S. cerevisiae (BY4741), S. paradoxus (CBS432)
Growth protocol Synthetic Complete (SC) medium at 30°C
All samples were collected at log-phase growth. Starters were grown over night, dluted to OD(600)=0.1 in 10ml medium and harvested ~5 hours after dilution when OD(600)=~0.5
Extracted molecule polyA RNA
Extraction protocol Total RNA was extracted using MasterPure™ Yeast RNA purification Kit (EPICENTRE).
Label Cy5
Label protocol Agilent Low RNA Input Amplificarion Kit (LRIAK) plus, two color p/n 5188-5340
Hybridization protocol Agilent Gene Expression Hybridization Kit p/n 5188-5242
Scan protocol Arrays were scanned using Agilent Microarray Scanner (p/n G2565BA) with a 5 micron resolution and photomultiplier tube (PMT) set to 100 and then rescanned with PMT=10. The images analyzed were from the PMT=100 unless data has reached saturation. The raw images were analyzed and quantified using Spotreader software (Niles scientific).
Description Comparative analysis of gene expression in two yeast species and their interspecific hybrid
Data processing Raw hybridization intensities were background subtracted and log2-transformed. Results of different samples from the same condition were converted into the same distribution using percentile normalization. Probes were then sorted into 10 bins of similar %GC and the log-intensities of each bin were renormalized to the mean and Std of all probes. Finally, the normalized expression was averaged over the technical repeats of each probe (each probe was placed at 3-4 different positions on the array).
