Sample GSM4050908 Query DataSets for GSM4050908
Status Public on Dec 31, 2020
Title sgu114vsby4743-1
Sample type genomic
 
Channel 1
Source name SGU114
Organism Saccharomyces cerevisiae
Characteristics strain: SGU114
Growth protocol strains were grown in YPD (1% Yeast Extract, 2% Peptone, 2% glucose) overnight at 30€™C in shaking.
Extracted molecule genomic DNA
Extraction protocol genomic DNA was extracted from over-night strains cultures with the phenol-chloroform protocol. DNA quality was checked through gel electrophoresis and photometric measurement.
Label Cy5
Label protocol The genomic DNA extracted was concentrated using the filter Microcon YM-30 (Millipore) and fragmented by sonication. The labeling of the DNA was performed, at 37°C for 2 hours, using the BioPrime DNA labeling Sytem (Invitrogen, Life Technologies), but using 100mM dNTP set (Invitrogen, Life Technologies) instead of the biotinilated nucleotides present in the kit, as well as the fluorescent nucleotides Cy3-dCTP and Cy5-dCTP of Amersham, GE Healthcare. Once finished the reaction, the DNA was purified with the Microcon YM-30 and the appropriate pairs of samples labeled with the different fluorochromes were combined in a single eppendorf in 450µL of TE (Tris-EDTA), pH 8.0 (Sigma-Aldrich). We used Human cot-1 DNA (Invitrogen, Life Technologies) to block non-specific hybridization, and Yeast tRNA (Invitrogen, Life Technologies) as coprecipitant.
 
Channel 2
Source name Wine grape
Organism Saccharomyces cerevisiae
Characteristics strain: BY4743
Growth protocol strains were grown in YPD (1% Yeast Extract, 2% Peptone, 2% glucose) overnight at 30€™C in shaking.
Extracted molecule genomic DNA
Extraction protocol genomic DNA was extracted from over-night strains cultures with the phenol-chloroform protocol. DNA quality was checked through gel electrophoresis and photometric measurement.
Label Cy3
Label protocol The genomic DNA extracted was concentrated using the filter Microcon YM-30 (Millipore) and fragmented by sonication. The labeling of the DNA was performed, at 37°C for 2 hours, using the BioPrime DNA labeling Sytem (Invitrogen, Life Technologies), but using 100mM dNTP set (Invitrogen, Life Technologies) instead of the biotinilated nucleotides present in the kit, as well as the fluorescent nucleotides Cy3-dCTP and Cy5-dCTP of Amersham, GE Healthcare.

We used Human cot-1 DNA (Invitrogen, Life Technologies) to block non-specific hybridization, and Yeast tRNA (Invitrogen, Life Technologies) as coprecipitant.
 
 
Hybridization protocol Hybridization took place at 65 °C for 16 h.
Scan protocol Fluorescent DNA bound to the microarray was detected with a GenePix 4000B microarray scanner (Axon Instruments), using the GenePixPro6.1 software package to quantify microarray fluorescence.
Description Arsenic-resistant strain
Data processing Data were normalized using the limma R package and DEGs (Differentially Expressed Genes) were identified with the RankProduct R package
