Sample GSM1405914 Query DataSets for GSM1405914
Status Public on May 11, 2015
Title MARV PBMC, Mky 071840 Day 1
Sample type RNA
 
Channel 1
Source name blood samples taken from the animals at different timepoints over the course of the infection, PBMCs isolated from whole blood over a Ficoll-gradient
Organism Macaca fascicularis
Characteristics animal id: 071840
cell type: PBMC
time point (days post-infection): 1
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using TRIzol reagent following the manufacturer's instructions
Label Cy5
Label protocol RNA samples were amplified and labeled with Cy dyes using the Agilent Low-Input Quick Amp Labeling kits
 
Channel 2
Source name Universal Human Reference RNA (Stratagene), commercially available
Organism Homo sapiens
Characteristics vendor: Agilent Technologies
catalog #: 740000
rna source: 10 different human cell lines
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using TRIzol reagent following the manufacturer's instructions
Label Cy3
Label protocol RNA samples were amplified and labeled with Cy dyes using the Agilent Low-Input Quick Amp Labeling kits
 
 
Hybridization protocol Labeled reference RNA was added to each experimental sample, then samples were hybridized to arrays in Agilent SureHyb-enabled hybridization chambers. After a 17-hour hybridization, arrays were washed with the Agilent gene expression wash buffers and then placed in Agilent scanner slide holders with ozone-barrier covers.
Scan protocol Arrays were scanned using the Agilent High-Resolution Microarray Scanner and raw microarray images were processed using Agilent's Feature Extraction software
Description commercially available human reference RNA from Agilent (Stratagene), used as a consistent control in dataset comparisons
Data processing Data were first background-corrected to remove noise from background intensity levels, and then normalized within the arrays using the Limma package in R (R development core team 2010). Following normalization, the reference and experimental samples were compared to generate log fold-change values that represent a change in mRNA expression (either positive or negative). Data were further processed by zero-transformation, where the normalized values of the pre-infection samples were subtracted from the subsequent timepoints of each monkey, in order to remove animal-intrinsic variables and focus on gene expression changes due to infection only.
