| Sample type |
RNA |
| |
|

| 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: C38113
cell type: PBMC
time: Day -8 pre-infection

|
| 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 |

sample type: Universal Human Reference RNA (Stratagene)
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.
