Sample GSM653842 Query DataSets for GSM653842
Status Public on Jan 07, 2014
Title 181P
Sample type genomic
 
Channel 1
Source name Total DNA from sample 181P labeled with Cyanine-5 (red).
Organism Homo sapiens
Characteristics tissue: Amniotic Fluid
Extracted molecule genomic DNA
Extraction protocol QIAamp DNA Mini Kit
Label Cy5
Label protocol Between 300 and 400ng of total genomic DNA were labeled using Cy5-modified dCTP by random priming method, according to a slightly modified Bioprime Kit protocol (Invitrogen). Absorbance measures at 532 and 650nm. determined the amounts of dye incorporated to the DNA.
 
Channel 2
Source name Total DNA from reference sample 20M labeled with Cyanine-3 (green).
Organism Homo sapiens
Characteristics tissue: fresh peripheral blood
Extracted molecule genomic DNA
Extraction protocol Chemagen magnetic beads. Chemagic DNA Blood Kit special (cat. num 703, Chemagen)
Label Cy3
Label protocol Between 300 and 400ng of total genomic DNA were labeled using Cy3-modified dCTP by random priming method, according to a slightly modified Bioprime Kit protocol (Invitrogen). Absorbance measures at 532 and 650nm. after removing unincorporated dye determined the amount of dye incorporation.
 
 
Hybridization protocol Hybridisation was performed as described in Wang. NJ. et al, Am. J. Hum. Genet, 75(2), 267-81, 2004.
Scan protocol Agilent Microarray Scanner (G2565CA - Agilent Inc., Palo Alto, CA). Images were extracted with Genepix Pro 6.0 (Axon, Inc) using the irregular spot finding features with default flagging settings.
Description biological sample used as control/testing purposes in the study.
Data processing In order to extract information from the GenePix generated files, we used an in-house developed pipeline called Bacanal (Lozano et al, unpublished). For lowess normalization of spot signals it relies on a bioconductor package called LIMMA. Values provided correspond to the log2 Cy5/Cy3 (test/reference) ratios.
