Sample GSM1139164 Query DataSets for GSM1139164
Status Public on Jun 20, 2013
Title Water column DNA_Arabian Sea_Station 1_150m
Sample type mixed
 
Channel 1
Source name Universal Internal Standard + 70-mer
Organism synthetic construct
Characteristics sample type: reference
Extracted molecule other
Extraction protocol DNA was extracted from the filters using the PureGene DNA kit (Gentra, Minneapolis, MN) or the AllPrep DNA/RNA Mini Kit (Qiagen Sciences, Maryland, USA) with slight modifications (as in Ward 2008).
Label Cy5
Label protocol Hybridization targets were prepared by digesting environmental DNA with a four cutter restriction enzyme. The digested environmental DNA were labeled with amino-allyl-dUTP (Ambion) during linear amplification using random octamers and a Klenow polymerase (Applied Biosystems). The reaction contained 3.96 mM d(AGC)TP, 0.44 mM dTTP, and 4.84 mM dUaa and was amplified for 3 h at 37°C. The Klenow product was purified and conjugated with Cy3. The Cy3-labelled target (1000 ng) was combined with 2x hybridization buffer (1x final concentration; Agilent) and 0.25 pmol of a Cy5-labelled complementary 20-mer standard oligonucleotide and incubated at 95°C for 5 min before being cooled to room temperature.
 
Channel 2
Source name Total DNA from water column, Arabian Sea station 1, 150m
Organism marine metagenome
Characteristics location: Arabian Sea Station 1
depth: 150 m
sample type: environmental
Extracted molecule genomic DNA

Hybridization protocol Samples were hybridized to duplicate arrays by overnight incubation at 64°C and washed.
Scan protocol The arrays were scanned with a laser scanner (Molecular Devices 4200).
Images were analyzed with GenePix Pro 6.0 software (Molecular Devices).
Description AS1.150m
This Sample represents 2 replicates.
DNA extracted from sterivex filter used to create 2 targets to run on duplicate arrays.
Data processing Quality control was employed to remove noise by eliminating features 1) in which the Cy3 signal was not at least twice the value of the control probes, and 2) in which the Cy3/Cy5 could not pass a Z test to find out the outlier values. The Z test was performed by calculating Zi = ri/(s/square root of 3), i = 1, 2, or 3, where ri represents Cy3/Cy5, s the standard deviation of the triplicate Cy3/Cy5 values. A feature is considered as an outlier if the Z is greater than 1.9 (CI = 80%).
Cy3/Cy5 fluorescence intensities were standardized to the highest Cy3/Cy5 fluorescence across the AOA probe set (normalized fluorescence ratio; FRN).
